Noisy Water Pump On A S6

Recommended Posts

Hi

We have a 2009 Virginia caravan which when using the water pump makes a loud noise, almost like someone with a hammer banging on the van. It may be that this is normal on Baileys but on our other vans the water pump operation was not anywhere as loud, I would appreciate anyones experiences.

 

Overall we are pleased with the van though its sadly let down by some very poor finishing. Such as mouldings not stuck down properly, silcone aimed at the general direction of the van in places. Whilst on the other hand there is a missing section of silcone by the sink. Why is it also an industry standard in caravans to leave pencil marks, I do not need these marks as an optional extra.

 

Regards

The problem is most likely your pressure switch it needs adjusting. Check in your Bailey manual it tells you how to do it.

My Senator 6 on board pump makes a loud noise. On the Senator 6 there is not pressure switch to adjust unless someone can tell me I am wrong?

Mark,

 

Try the search option for this one as it has been discussed at length, personally I don't think you will silence the pump but if you do please let me know how you did it.

During the 2 years I've had my Arizona I have attended a number of large rallies and had the Whale engineers out to try and sort the noise problem. They have been very helpful even replacing the pump, piping, surge protector and external fitting. Still noisy but not as bad as used to be. This is the main downside to an onboard pump.

I think the important thing to remember is Whale did not design a noisy pump, I've got one and we have to be very quite to check it's not running

Today as it happens I asked Linda 'has the water run out?' because I thought I could hear the pump, no she replied and she was sitting over it!, had to put the tele on mute before we could be sure!!

 

Having said that, it was as noisy as hell when I first installed it but once I understood the problem it was easy to solve

 

I found air being sucked into the pump with the water is the main cause of noise and poor mounting transmits this noise to the floor and the floor then acts like a loud speaker, cure the air leak though and the floors got nothing to amplify.

Semi rigid pipe attached to or touching the floor/walls will have the same effect as air in the water makes them vibrate the same as the pump.

I've got a series 7 Pageant and Whale replaced the pump FOC. This did NOT solve the noise. The noise is slightly better and I've tried everything. After speaking to the chap next to me on site (in a Abbey) he said his had been noisy from day one and now he was in the second year of ownership.

I've put it down to that's the way it is. There was a note in my caravan from Bailey when I collected it to the effect that this type of pump is noisy anyway.

The green light showing when the pump is running stopped working months ago (and I can't be bothered to take the van back to the dealer until it's first service) and because the pump is so noisy at least I know whenh it's running.

Don't worry that's just the way it is!

I am on my 5th Bailey and overall find the brand very good. Last year we bought a new S7 Burgundy and had our first experience of an onboard pump. I believe that the on board pump spoils an otherwise superb caravan. I know that most other makes are fitting these with similar complaints from users.

The problems I had with the pump included excessive noise, hot water contaminating cold supply causing taste problems and trapped air causing the hot tap to spit. By the end of the first day the hot water pipe had kinked where it passed around the rear of the hot water tank. I fitted a 90 degree bend which slightly improved the situation but did not bring a solution. Part of the problem seems to be that under certain condition the filter floats in the tank letting air in.

After about 3 weeks use I decided that I had had enough. So I investigated changing from the inboard back to the older external pump system. Fortunately from many years of caravanning I had most of the parts I needed. It was easy to convert the wall socket to electric by adding the probes from an old unit. I found that the newer socket did not have a none return valve but by changing tha back plate I added a valve. I positioned a pressure switch which added another none return in the line where the internal pump had been. I cut the line to the water tap and inserted a new filter with a renewalable element. and installed a 'pump on' light near the tap.

The external submerged pump works like a dream. Cold water is drinkable. The hot contaimating cold problem has disappeared. The taps no longer spit and the noise problem is gone. Water pressure is fine.

The internal pump seems to be a higher pressure pump but the energy is spent drawing water and air through the filter which appear to lack sufficient weight. The lack to a non return valve at the socket seems to cause additional air entrapment when the water is changed. Whilst the internal pump overcomes the Winter freezing problem I spend most of my caravanning time in the warmer weather.

Personally, I fail to see any advantage of using an internal pump other than maybe an increase in pressure. I also fail to see any advantage in having a pressurised system rather than a microswitch system. I am dreading the day when I change the 'van and am confronted with an internal pump and pressurised system.

Gerry,

 

There is no need to dread the day, the noise from the pump really is not worth mentioning, it isn't like the old internal pumps used to be, when in use they would wake up the whole site, in fact many years ago that was the reason I changed to a submersible.

Have to agree, the noise from my pump is barely noticeable, its a moving part, it must make some noise, but it certainly does not bother us in the slightest.

Like you mines a series 7 Burgundy and we are delighted with it.

Just a quick pointer to beware of, check the connections at the hot water tank, mine were both leaking where the cold and hot pipes are clipped just befoe the tank.

Also does your pump running light work, cos mine stopped after about two weeks?

Also and this applies to all Series 7 owners, check the water pump in the Thetford toilet compartment that it doesn't drip onto the holding tank. If like me you wondered where the flush fluid was coming from, check the connections, there has been a common problem with the pump next fracturing allowing the flush fluid to drip out. You will note this is not connected using a Jubilee clip which is part of the problem. Thetford are aware and kindly sent me a new pump which I fitted msyelf this time using a Jubilee clip

Happy caravanning and it pays to be a competnent DIYer

We've got a S6 and found the pump to be noisy especially compared to an external submersible - then we tried a different way to bleed the pipework - basically follow the instructions in the Bailey handbook. Firstly, ensure that the "O" ring on the inlet is in good nick and that it's lubricated with silicone grease so that air can't be sucked in. Open the hot water tap in the kitchen and then turn the pump on and let the tap run until all the air has been dispersed, open the cold tap and do the same. Then let the air out of the bathroom taps - problem solved. I can hardly hear the pump now. The pump running light works as well.

I to have had a noisey pump, which I felt was because of the mounting on a raised box on the Senator series 6 and the raised box acting as an echo chamber. After trying all the other fixes described to no avail i made a simple change.

 

Removed the four screws that mount the pump to the Echo Chamber and I had some High Density Foam about 10mm thick that (The sort of Foam that Circuit boards are usually packed in) Cut a 15mm square of foam for each mounting point and placed it under each mounting.

Replace the screws but (DO NOT OVER TIGHTEN) Tighten just enough to trap the foam so to let the foam act as a shock absorber and voila quiet pump just a slight hum as it whirrs away.

Just need to sort out the shortage og Hot Water in the shower now.

This pump issue appears to be problem across several caravan makes.

They all appear to say they supply subcontract suppliers with some form of specification or user requirement and just assume all is well.

Does anyone. ..from any manufacturer actually test or site test the componants they are installing in caravans that can now cost more than the car towing them ?

My Flojet pump was put together in China. ..Flojet say it is engineered for life !!!

Mine appears to be failing after 12 months !

No doubt the major manufacturers will eventually " wake up to reality " that if you pay good money for a product you expect it to work.

There is now a new mood in the Country.

From day one by new Wyoming s5 2006 had a noisy pump!

and more or less got the reply “Yes they are” “ some thing to live with”

 

The hammering effect seamed to me, to point to the pressure switch….. but could not find it! …… So contacted Bailey had this reply

 

 

The pressure is not adjustable.

 

A noisy pump would suggest air is being trapped in the system.

 

The priming procedure is extremely critical with this type of pump

 

Details on P3. 2 of the handbook

 

Please refer to your retailer if you experience no improvement

(she was having a laff…)

Well I follow the above to the letter. . but still had the hammering noisy pump. ....which seem to get louder when turning the water tap off at the basin.

After a six week touring was about to change the whole unit, back to a pump that fits in the outside water tub….for a bit of peace.

But on inspection appeared to be a big job. (So plan B)

 

So I replace the mounting board that holds the change over taps attached to the pump. .. and replace this with a solid block of wood ( to try to the remove banjoing hammering effect ) while doing this I had to remove the pump from the floor fixings.

 

I dececided to remove the front end of the pump (4 screws) to ensure that it was not blocked. .... once removed it appeared to be a seal unit in which the impellor is mounted. ... however I could now view the pressure switch, there was a small amount of plastic swaff around. ..... and on inspection found this to be from the trigger end that operate the switch. This had the effect of the pump working overtime to reach a higher pressure point in order to switch off. The cure was to remove the white plastic cap on the end of the trigger valve (the part that fits into the impellor side) and place a small washer inside the cap and refit, this has the effect of added a tad more length to the trigger valve.

I place a small amount of Vaseline to avoid wear again on the other end of trigger valve.

Reassemble the unit back on to the pump house motor ( a little care need) and replace the four screws and tighten (if at this stage you hear the click of the trigger, then the washer need to be thinner)

 

Refitted the pump to the water pipes. .... and tested. ......Hammering gone. Magic

 

So noisy pump cured… just a slight humming when running no problem!

 

Hope this helps
