Whale Universal Pump Failures

I was just getting my motorhome ready for a few days away before Christmas. The water system had been drained down and on refilling, my water pump will not prime. I have been suspicious the water pump seals have been on the way out for a few months now and the drain down and 6weeks of inactivity seems to have been the last straw.

This is the fourth time I have had a pump failure and I only seem to get about 2years life out of the seals.

I have been in touch with Whale who did on the first occasion provide me with a free replacement pump. The second time I bought a replacement pump and on the third occasion I tackled them again about pump performance and they sent me a set of free replacement seals. So I have no axe to grind about their customer service but I remain unhappy about the pumps performance.

Its a good job the pump is easily accessed and I can in fact change it and the seals quite rapidly.

Does anyone else have this problem or can anyone advise what is the likely cause. 2 years is a very short life in my view!

Too short in my opinion, I recommend replacing it with a Shurflo, I've just replaced ours, it was 10 years old and it had a hard life ..

No problem with seals but the micro filter blocks occasionally, like you PD I know how to fix it now, takes no time at all.

Has no one else had any problems with a Whale Universal pump?
Surely I am not the only one?

Not so far Peedee, by by the Lord Harry will you get a rollicking if I check mine tomorrow and it's knackered!

Mr Sod (he of The Law) has been having a go at me lately, so if my pump has had it you will get the blame for alerting him to another possibility for mayhem and mischief!

Have a good trip (envy, envy) we can't get away again until late Jan.

Cheers, and a Very Merry etc.

Well if it is only me I start thinking it must be something I am doing???
Cannot think it is the water because that varies so much with the areas you go to and in any case Whale claim even salt water will not do any damage. So that would only leave chemical treatments when flushing the tank, I only ever use Puriclean and it is claimed to be perfectly safe for this purpose, so I am mystified.

It's Mr Sod again. It's obviously not just me the bu**er is having a go at.

It couldn't be plastic swarf in your system could it, dating right back to when it was new? Just a thought, but that was the cause of a problem I had with a leaking dump valve, and it was a swine to flush it all out.

Cheers

There is an in line filter which should take care of any foreign matter which creeps into the system. In any case, I have never found any trace of any foreign matter in the pump housing. What seems to happen is the seals harden and lose their elasticity and then do not seat down firmly. The first signs of the seals failing is pressure in the system is not being maintained and the pump will cycle now and again. There are no leaking taps and what is happening is water is draining slowly back into the tank until there is a sufficient drop in pressure tap side to start the pump again. Eventually the pump fails completely and will not prime. You can quite easily prove it is faulty because you can blow in both directions through the pump. You cannot do this with good seals and you can only blow through in one direction (the direction of flow). I have just changed a set of seals and the new ones were definitely softer and solved the problem.

I fitted new seals to the pump before spending a brilliant few days in the Cotswolds. Cold but a fitting place to visit for a bit of early Christmas spirit!
(read that how you like) The new seals look like they are a different compound to those previously fitted, I guess only time will tell if they last any longer.

I have just updated my motorhome "Live in Report" for the end of the seventh year. If you want to read the whole story click on the link below my signature.

Drink whiskey instead!!

Seriously, we have never had any complaints about Whale seals although there are some posts about toilet seals getting hard and can be softened by immersing (I think) in olive oil.

Fit a F iamma pump £58 and your problems solved. We have plenty of those,

Regards
