Low Pressure/no Water In Taps

Recommended Posts

Hello and good evening everyone,

 

I'm having a tough time getting water to flow from taps both in bathroom and sink. it just trickles out and then stops. if I dump some water out of the hot water tank the submersible pump kicks in and I assume tops up the tank and naturally clicks off.

 

There appears to be two pressure valves/switches one on the inside of the submersible pump unit, the other one a large white one with a twisty top that, is inline about two foot into the cold water supply coming into the caravan.

 

Would I be correct is assuming that one or both of these needs to be adjusted? and if so how would I do it?

 

all help greatly appreciated, caravan is 04 Bailey Ranger 5 series.

 

Many thanks,

 

Barry

If the pump refills the hot water tank and the pressure switch shuts the pump off when it's full then leave the pressure switch alone as it sounds like the pump is producing enough pressure to operate the switch and the switch is working OK. Having a tweak just to see what happens will mask any other problems that you may have.

 

Check all the cabling for bad or corroded connectors, especially where the pump connects to the van.

 

If the tank is filling then the pump is obviously managing to pump water. Are all the taps having a problem, kitchen, bathroom, shower, both hot and cold. We need a bit more info.

 

Have you made sure that the pump is fully submersed and that you've bled all the air out of the system.

 

Start by dunking the pump up and down in the aquarolll to dislodge any bubbles before plugging the pump into the van. Make sure the O ring on the inlet connector is in good condition and lubricated with Silicon grease, olive oil or even margerine. Dont use oil or vaseline as they'll damage the rubber.

 

Close all the taps and shower then open the kitchen hot tap and turn the pump on to fill the hotwater tank and bleed the air out, when the water is flowing with spitting and spurting shut the hot and do the cold when that's OK do the bathroom sink and shower.

 

If that doesn't sort it then check for limescale in the taps or any filters than may be in the system. The pumps usually either work or they don't, I've never had one that doesn't produce enough pressure unless the wiring or battery voltage is low,

 

Have you checked your battery voltage, are you running it from the mains. See what voltage you've got at the pump connections when the pump is running, it should be well above 12 - nearer 13 if you are connected to the mains.

 

If the voltage at the pump connections is say 0,5 of a volt or less than the voltage across the battery then I'd have a good look at the wiring & fuses.

This may be way off but we had a similar problem in our Bailey. The water pressure coming out of the taps was poor. Both kitchen and bathroom hot and cold but the shower was ok. It came to a head first outing this year immediately after a service so I thought everything should have been ok.

Anyway the mixer taps have a combination of plastic and mesh filters removed by unscrewing the end of the taps, the filters in both taps were well blocked. I binned the plastic ones and cleaned the mesh ones and bingo lovely pressure again.

Worth a look.

Hi Guys,

 

Thank you for taking the time to reply. I've drained the tank and it has refilled pump clicks on tank fills up and pump clicks off, so that appears to be working,

 

turned on the electric heater, left it twenty minutes then drained it it was lovely and hot, refilled the tank. took off the red pipe and it kinda has a T junction with a small clear pipe draining outside there is a one way valve in there sucking on the small/narrow end shuts the valve, blowing on the small end opens the valve. is this functioning correctly?

 

All my taps kitchen and bathroom both hot and cold don't work, would these two valves be malfunctioning ? following both pipes there are the same as they were put in in the manufacturing process, all neat and straight.

 

I will try and look at the taps, perhaps as you suggest may all be blocked do I have to take out the tap units or can I access the filters by taking off the knobs?

 

Many thanks once again. ....

I also forgot to mention with the red pipe and valve removed when I turn on a hot tap water comes back out of the pipe. .... puzzled I am. ....

This red valve does it look similar to this one, if so its a breather valve and it should let air into the tank

I think the tap filters are at the outlet end of each tap.

@Paul_B

Thank you for your reply, the valves are different styles, I will upload pictures shortly and perhaps experienced eyes like you guys have something may jump out at you that I'm missing.

 

@Milky Way appreciate you taking the time to reply. .......

 

Going away this weekend for the last outing before winter bites, will have all winter to figure it out, but would have loved to have had it working. ... perhaps there is time yet.

Its the same thing and it needs cleaning or preferable a new one, when draining down the hot water tank, always open the taps first to let the water out of the system.

The breather valve in your case the white one lets air into the tank when draining down, if you open the yellow handled dump valve first its possible that it can suck dust into the tank through the clear pipe and clog the valve, allowing water out when the tank is filled again.

@ Paul B thank you once again for your interest and input.

 

But I think I've found out what the problem is. I believed that with my caravan plugged into the mains all was being powered by mains however that is not so. this evening my leisure battery died and with the water heater, water pump, and most internal lights.

 

so now the mains is powering all my sockets, two pull cord lights, fan heater and fridge, now I know why my taps would not work.

 

Is this normal (it cant be surely) or does it sound like part of my control panel is acting up? attached picture.

 

Please help an idiot. .....

It sounds like the charger, sometimes the lead can come out of the back of the charger on some types

Quite possibly could be Paul as when I took out the battery from its housing both wires coming from the internal charger were just loosely wrapped around the battery terminals. that would certainly account for systems slowly failing in the caravan.

 

I'll replace charger tomorrow and ensure good contact with terminals.

 

is my electrical set up bazzar, or would it be factory standard, the caravan looks untouched from DIy'ers and all looks professional and tidy.

 

Indebted for you assistance

I'd wire it up properly and check the chargers fuse/s first

Hi Paul B. ........

 

Just stopping by to say a very big 'THANK YOU' and to everyone else that assisted me.

I wired up the charger properly, found that there was no fuse inserted in the plug, charged the battery overnight and today EVERYTHING works just as it should, lashing of hot and cold water with great pressure, all lights and equipment work just as it should.

 

So relieved, happy and grateful for the advice, we are now really looking forward to our last two nights away in our caravan before winter bites.

 

regards,

 

Barry Sullivan.
