  1. update: i got a lucky 1 day delivery, just finished installing the new pump. works great, even though as i expected, flow is bit lower than my old one. just in case someone else needs info about the pumps, here it is: Old pump - crystal maxi pump (no idea, but i think it was about 15-20l/min as new) New pump - https://www.amazon.de/gp/product/B001CV02U4 (10l/min) - Yes it's not UK one, but anyone outside UK, this pump has exact same fittings as the old one, so I guess they're all standard. Wire was bit longer, but who cares, better longer than shorter. you can always cut it. as I said, it works fine, but pressure is not that good. I had to re-adjust the pressure switch, otherwise it wouldn't turn off. I think by about 1 and a half turn or bit less. I tested shower too and it's ok. I'm not much of a pressure fan anyways. when I wash hands, i prefer lower pressure, so water won't splash all over and when i take shower, i also prefer lower pressure so that hot water lasts longer. ofcourse you can adjust it from tap, but it's so much easier to just turn the tap onto max than slooooowwwlyyy turning it on until you got right pressure. so for a pump worth about 15 quid, I think it's good enough result.
  2. yeah I know how basic physics works, it's just that I couldn't find any specs on my current pump. It felt like 5-6l per minute. I didn't notice significant change in shower, I mean that shower's tap is about same level as sink and basin and if i lower the shower from near ceiling to below basin level, then I see no visible increase in flow, so I assume that 10l pump will do the trick. I know it's about 50w power and says "crystal maxi pump" on it, that's all I could find. anyway now it's too late, already ordered the 10l/min one. Thanks everyone for all the info and ideas. I'll try to come back in few days and let you all know how well that 10l pump works.
  3. Yeah i know it should turn freely, but water doesn't run thru the pump. If it did, it would short circuit. There are water tight seals everywhere. That's why i'm having hard time opening it. I was counting on it, but thought I ask anyway. But well, I have nearly no hope in fixing it, do you or anyone else know how much flow rate should I be looking at? I just looked on google and they saying that standard ones are about 10l / min. There's a cheap one on amazon, might just grab that one and see how it works. From experience, I think mine might have actually been bit below 10l/min. Took me more than 2-3 mins to fill 15l washing machine, so I guess 10l/min should work better than the old one. Edit: couldn't bother waiting, I ordered the cheap 10l/min pump, should arrive by tomorrow. For 15gbp, if it gets me water out of shower, that's good enough.
  4. Well I might have overstated a bit, it does move, but very, very hard. I popped the bottom "cap" off so I was able to access the head of the pump, i can turn it with fingers, but it feels very stiff. So I assume bearings, but I'd like to give it a go with oil ... that is if i can get it open. and yes, I meant the fuse. sorry I'm tired, was gonna take a shower and go to sleep and then this happened
  5. my camper was made in 2003, but I have no idea if it has been replaced or not. I bought it from second hand caravan dealer who refurbishes them. pump looked quite new to me. and no thx, those services cost a fortune. I already looked on amazon, i can get replacement for like 15 - 25 gbp. It's not same and probably bit less power, but looks identical. I just rather fix it if there's a way. I got the bottom cap off, but don't think it can be opened any further. It's just stuck. putting power thru does make it click, so I'm thinking if i can get oil in the right place, it might actually start working. I've seen same thing with PC fans, where it gets completely stuck, but PC fans have that rubber cap on back, you pop it off and squirt some oil in it, give it 10 mins and spin it a bit and it will be good as new. but problem with submersible one, is that obviously it's protected against water, therefore also oil. So I can't get oil into the motor itself.
  6. Hi. My pump just failed, is there any way to open it? I know that you're able to open bigger submersible pumps, but this 12v one seems quite sealed and I can't find any screws or other clips to take it apart. Are they built in a way so you can't repair them or do I have hope of fixing it? Basically what happened, is that it just stopped and 12v breaker broke too. I took the pump and instantly found a issue, it's completely STUCK and won't move at all. I tried moving it bit with pliers and it's very hard to move it. I tried squirting some oil into it (with very little hope) and as I expected, it had no effect. I also tried powering it from 12v DC adapter and something just clicks in it, but it won't move at all. I assume the ballbearing broke or it's just very dry. Either way, I'd like to take it apart, so is there any non destructive way of opening it and attempt repairs? I forgot to mention, it's older whale pump, but I really think there's no difference as they're all some sort of standard pumps that are built in same way. I looked some up on amazon and there are lots, but they all look alike with same connectors. Thanks.
  7. I have no idea, but with the original I always had higher pressure bursting out of hot water tap when I heated it from cold to hot. I had no idea about it at first, but after first couple of times, I started manually venting it 1-3 times while it was heating as pressure seemed bit too much (turning tap on / off for a second) Before it broke, it no longer did that. I used it 2-3 times before it broke and it didn't build up the pressure anymore, it should be other way around, but go figure. . no idea. I just finished installing the new one and didn't have any pressure build up issues. I filled it with cold water and heated all the way up to like 65C (max is 70). It is advertised as "electrically pressure resistant". I have never heard such term before, but common sense tells me it has some sort of expansion tank that is operated electrically. Also my pressure switch on camper is turned to quite low, so there should be more than enough room for expansion + the drain / pressure valve. My camper actually has quite long pipework. It runs all around the edges .. there's at least a good 20 meters of cold pipe there and another 15 of hot. Water comes from right side near front, then it goes all around from front to the kitchen area (other side, middle) and then from other side it runs all the way to shower and bathroom basin. Total lenght of my camper is about 5.9 meters inside. I don't think there will be any issues. However what I don't understand, how would that valve help me anyways if it's only installed between cold water? It would only make it worse as all the pressure would be forced into hot water pipe, but without the 1 way pressure valve, it can also go back into cold water pipe. Just took a shower and 5-10 mins after shower it was already fully heated up again, I'm glad I chose not to fix the old garbage, 10 liter 450w is just not enough, but 15 liter 1500w does excellent job with low pressure! I replaced the EU plug with UK one and connected it into smart plug, so I can set schedules or operate it remotely. Also actual wattage is 1365 (as seen on the screenshot). Thanks again @everyone who helped me figure out the pipes and connectors. Here are some pictures of my "frankenstein".
  8. it doesn't say much at all. it has only couple pictures and that's it. i think it's pointless too to include it as camper ones are lower pressure anyways, so there's no risk to "blow" the pipes. I tried the metal one on shower and it restricts the flow even more, so i think it's bad idea to have it. I mean pump is not powerful enough to freely flow that metal valve.
  9. It's also a pressure reducer, if pressure gets too much, it will push the spring up (as when you do it manually by moving the lever into open position) and it relieves the pressure. Or why does it have that release there for? it's under sink tank, so turning the valve on does absolutely nothing as all the water is below the valve. But can you please answer my question, is it needed or not? Personally I don't see any use for it in my case, but I'd like to be sure. thanks.
  10. Quite sure I got everything I need, however I have one quick question. Do I need to install this 1 way valve for new heater? (pls read below before replying). I ask, because I already have similar thing between the current cold water pipe. It's about 60cm from where I want to install the new heater. This is what i have: Would just like to know if the current one is enough. I would install both, but space is quite limited and it would be better if I don't have to install it. Thanks.
  11. hmm indeed it's 450w in manual, I don't know why I remembered 500w, maybe because when I checked via smart plug, it went up by 500w. I guess not everything is as precise as it says in manual. anyway I got my new heater just today and I also ordered simple flexi pipes from 1/2 to 10mm, just matter of installing now. Before I go on installing it, do I need that 1 way / pressure reducer valve? I refer to this valve my heater came with one and it indicates I should put it on input (cold water) and as I understand in normal house hold it's needed for over pressure and to prevent hot water from going back into cold pipe as it heats up, but my camper already has one built into the cold water pipe and the drainage pipe goes straight outside through the floor, so do I still need it? Thanks.
  12. Thanks @ everyone who have given me valueable info regarding the connectors and pipes. However I decided not to take any risks and took the pipe off and measured it. It was far easier than I thought, the fittings were basically hand tightened and refitting gave me no problems or leaks. Indeed it's 12mm outside and 10mm inside. I'll get some extra pipe and correct fittings and will try to remember to come back and post some pics once I have fitted the new heater.
  13. Sorry for so many questions, would this work? https://www.amazon.de/gp/product/B07NW4W8CY If not, can someone please take a look at the different types this listing has and point me to right one. One I linked is 12mm to 1/2 female, BUT my caravan pipe is 12mm from outside right? so it means 10mm inside? One seen on the pictures above, is 12mm to 3/8 and as seen above, it looks like 12mm would fit my pipes. My guess is that I should go for the 10mm one as inside of pipe is smaller, but I'm not sure if I'm able to push that pipe onto 12mm. I can't afford to order wrong stuff at this point. Thanks again.
  14. Yeah I just realized it's from side to side and easier to measure. But I also realized I might actually have the fittings, I started looking on amazon for 12mm to 1/2 and all I find is garden hose connectors, it seems like it's same as regular garden hose? While ago I did my aquaroll and I bought regular EU filling device (don't know what it's called, the thing inside aquaroll) and it uses the regular tap connector (1/2 inch?). It looks like 12mm slide on, but I'm not sure if caravan pipes go around it, i'd have to actually disconnect my current heater, but it would mean no water .. so I can't do that yet. Can anyone please take a look at the pictures and let me know if that's what I need. Thanks. EDIT: sorry nvm. It's 1/4 thread, but same seller has 1/2 to 12mm (same one as on my pics). So I guess that's the one?
  15. I think it's same then, visually it looks same too. How would I go about measuring if my pipes are also 12mm? Can I just wrap piece of something around the pipe and make a mark on it with marker or pencil and then put it flat on tape measure? I mean is the 12mm the outside diameter? I'm guessing inside doesn't really matter if I'm gonna get a push fit, since push fit goes around it and not inside, right? and well yes, I don't plan on removing the old tank, I just want to disconnect pipes from it and put them into new one. should be easy enough. Thanks for confirming. I think that's safe to say that rest of EU uses same then. Thanks again everyone for the info, I think I have enough info to get the parts! I'm going with the 1500w 15l tank and 12mm to 1/2 push fits. Just in case I'll wait couple more days to see if i get reply from Coachman. I also contacted the person who sold me caravan (small refurbishing / repair company) and hopefully they'll confirm that it's 12mm.
  16. Thanks, that's quite close to what i'm looking for, but are you 100% sure it's BSP? Someone above just said that 1/2 is not same as 1/2 BSP. Take a look at this one https://www.amazon.de/en/dp/B00VU032WC It says 1/2 inch connection and since it's EU standard, I assume all of those hot water heater tanks are same connectors. You can tell from images, that they all look same. The image of that valve thing, it's same on both, so I'm 100% sure they're all 1/2 inch, but someone said it's not same as 1/2 BSP. The push fit you linked, does look like it will fit tho. So your idea would be to directly put the pipe into it? What about the overflow, or whatever it is, I'd need a T connector too then? Sorry if I ask too many questions, but you thinking that my caravan pipes are 12mm? thanks again.
  17. thanks, but unfortunetely that's too expensive for me. As I linked above, I'm 99% sure i'll buy this - https://www.amazon.de/en/dp/B01L22S8OE Yeah 10l is not too bad when it's fully heated up, but 500w heating is horrible. at winter I had to wait minimum of 50 mins to get warm water and it was gone very fast. I could barely wash my hair and it started getting cooler. I also have portable washing machine (15l?) and that doesn't really work. I can barely get it half full with warm water (not even hot, just warm). It's ok and been doing ok with it, but ok is not fine. If it worked, I probably wouldn't bother .. but as it broke, now it's good time to upgrade. Same as I already linked https://www.amazon.de/en/dp/B01L22S8OE I don't think I can find a better one. I literally spent 2-3 hours looking thru 1500w tank heaters and this seems the best option. There are some cheap chinese ones for like 60 eur, but they have 1-4 reviews, I can't rely on stuff like that. I've bought some cheap chinese stuff before and it's more headaches than it's worth. I rather pay bit more and get a decent one. This one has good reviews and is in the cheaper price range. And yes, my plan is to put it next to the old one. I'm not expert on boilers / heater tanks, but does it matter which way the heater tank is? I can turn it on its back or upside down and it will work the same right? I just want to be sure, because I think I might have to put it on its back. Either way, I'm not really worried about finding place for it, my biggest concern right now is finding the right connectors. Thanks again everyone for feedback and ideas, but it would be absolutely brilliant if someone could tell me 100% which connector type would fit the existing caravan pipes (maybe someone here has same heater or caravan or has done work on one?). I refer to the part that connects to the existing tank (One I took picture of, hot and cold connecting to tank). I want to undo those fittings and connect them directly to new one. I'm hoping I can find a flexipipe (or whatever it's called) where one end fits the pipes on caravan and other end would directly go to the heater (1/2 inch). At some point I plan on selling this camper, could be few months, could be years .. so I don't want to go too crazy with DIY. In meanwhile I also contacted Coachman via official website and asked about the fittings, but I have very little faith in getting any help from them. I will sit on it for a day or two, but I'm 99% sure I will order the heater tank that I already linked above, as it seems like best option in my case.
  18. oh no no, sorry for confusion, I mean I want to disconnect the water from the tank / boiler, so I can take a water fitting with me and go to local store and show what I need. But there are no valves to turn water off at the tank. Also I looked other water heater tanks on amazon and 100% sure that all the connectors on the EU boilers / tanks are 1/2 inch. So my missing link is what goes into my caravan. I guess worst case scenario .. I have to turn pump off, drain it and take it apart and then be without running water until I can figure out what's the missing link. Unfortunetely I don't have any propane left. I did set it up to take EU bottles, but I have no car and it's not like you'd walk on the street with the gas bottle or even worse .. take it on a bus or train, it would be bit .. odd lol. I wanted the 1500w heater anyways .. so maybe it was good thing that this piece of Rubbish broke. Now I have a really good reason to get a new one.
  19. new heater / boiler should have 1/2 inch. At least this seems like standard in EU. I spent few hours on looking for a new suitable heater, that is no more than 15l and 1500w (to keep size, weight and power consumption down) and most say in description that it's 1/2 inch. That's not even the biggest issue, I have plumber friend here who would know exactly what type of connector the new EU heater uses, but he has no clue about UK standards or caravans. So biggest problem is the caravan side, I have no clue what I should be looking for. If someone would know solid answer to what the connector is called, I could easily search for converter on amazon, but not knowing the type of connector, makes it very hard to even search. Additionally, as my heater is busted, does anyone know if there's a way to disconnect it and still have running water? I don't see any valves I can turn off to isolate the tank. If i could remove some fittings, I could go to local shop and just show what I need .. but I can't remove anything as I still need running water. I was thinking to just smush something in the pipe and use that clip to tighten it back up .. but not sure if that's a good idea?! Thanks again for trying to help me out. I think I will just order the new heater tank and then figure out what goes where.
  20. thanks, that's a start, but I still need more specific answer. I mean what kind of connector do I need exactly, is there some flexpipes or do I have to get EU flexpipes and then a converter to fit from caravan to that flexpipe? Or is there a simple solution, like a converter/flexpipe 2 in 1, where one end fits caravan and other end fits EU standard (heater)? The ones I looked on amazon (EU standard), say that it's 1/2 inch, which translates to 12.7mm, so I guess that's the 13mm you referred to? At this point I'm staying in my camper and as of yesterday I have no hot water, so I need the simplest solution possible, I don't care if it looks right or not, as long as it functions, that's all I need. Hope someone can link me a specific connector / converter that would do the trick, it would be great help. thanks again. EDIT: I mean something like this https://www.amazon.de/-/en/dp/B00HYXOEQW Obviously that's not the correct one, but it would be perfect if someone here could link me the correct one that goes directly from my caravan pipes to the the heater I want to buy (one I linked above). So I can just unscrew the old one and put them directly to new one and that's it. Thanks.
  21. @Silversurf please refer to my new topic that I made here - https://www.caravantalk.co.uk/community/topic/150119-i-want-to-install-new-electric-water-heater-need-help-with-connectors-please/ I have explained everthing in detail and included pictures. Yes it's electric / gas hybrid, but I don't plan on removing it. I just want to disconnect water and put a new one next to it, there's enough room. definetely not. It says 500w in manual and I also have smart plug in between the main cord that comes into camper and it confirms the 500w.
  22. Thanks, but I already opened new topic as it's more related to installing a different heater tank than trying to fix this one. I won't bother trying to fix this heater (unless someone tells me that I could buy new and more powerful heating element for it, 1500w instead of 500w would work). I was already thinking about getting a more powerful heater as 500w is just not enough, so here's the new topic about new heater - thanks, but amazon UK won't deliver anything outside UK, so it's rather useless to me. Same with caravan spares, EU places have parts only for EU campers, not UK ones. caravan engineer is out of the question, I would not be living in caravan if I had money to throw around. engineer would easily charge 300+ eur for a simple repair. I do everything myself and I know how, only things I don't know, is name of each connector and pipe that I need. That's why i'm asking here. electrics and plumbing is kids play if I have connectors that I need. anyways I won't bother with this garbage heater, I already opened new topic. I want to get a new and more powerful heater and install that one instead. Please refer to the new topic I made. Thanks.
  23. Hiya. Recently my built-in 500w water heater broke and I decided not to even try to repair it, because 500w 10l is just not enough for decent shower anyways. I have 2003 Coachman Amara 580, but I'm not in UK at the moment so I plan on buying something like this - https://www.amazon.de/en/dp/B01L22S8OE But it seems like connectors are not going to fit, or do they? I don't know if UK and EU standard connectors are same or not, it looks like it might fit. Can anyone please tell me which convertors / connectors I need (if any) in order to connect that new water heater in my camper and make it all work? I have taken pictures of the connectors and pipes that my camper uses (see the pics below). My original plan was to leave built-in tank as it is and install the new one in bathroom's closet, so it would work only for shower, but now I think it's easier to disconnect the pipes from built-in tank and connect them directly to new one instead, any ideas? Either way, I need help with converters / connectors, it would be great help if someone could give me ebay or amazon links to needed converters / connectors that I need in order to make it work. Thanks. These are shower pipes.
  24. Those who wonder about the breaker, it kicked out the one in camper and also the one in the house. I tried several times and as soon as i turn water heater on, breaker goes out. definetely something broke. Anyway I have decied that I want to install a more powerful one anyways, this 500w is just taking too long to get hot water anyways. I'll open new topic regarding connectors, as I don't know which connectors I need to convert camper connectors to regular ones.
  25. I literally stated in the post which camper I have and I said i'm in EU. EU has same regulations everywhere. only UK has different plugs and connectors, rest of EU has exactly same standards. I'm not talking about European Union, I mean EU standards. We have 3 major standards in world, EU, UK and US. I thought it's common sense and everyone knew what EU standards mean. Just like UK sockets are different and they're called UK standard, while EU sockets / plugs are different and they're called EU standard, same goes for everything else. Plumbing, windows, gas ..etc. EU standard is same in any country that is considered as EU standard. Common sense to me. I just don't know if UK standard pipes and water connectors are same as EU ones. Visually they look same, but thread and size could be slightly different. that's why i'm asking. Also how does tow vehicle help with any of this? not like I can take my car's radiator and use it as water heater. And if you must know, i don't have a car! Camper is parked in yard and won't be moving any time soon, so I don't understand how any of this info helps you understand the issue with my heater? Also how do you know I don't have multiple campers? Maybe i'm a camper dealer / refurbisher and I own several campers, I can't exactly list them all in my profile, can I? So I explain specific post what I have and what I need help with ... but you seem to get mad because I put all this info in a post instead of on my profile. I don't mean to be rude, but it's just odd that you're not able to read it out of the post I made. Yeah I'll try to take it out soon ... but I think i'm going to just buy electric boiler and put it in bathroom closet. looking some on amazon right now. maybe 30l 1500w is good idea, not sure if i need 30l tho, it takes longer to heat it. so maybe I go with 15l 1500w, should be good enough. current one is only 10l and 500w. Still not sure about connectors.
