hi guys
i have 2 pumps in a van (2 man system)
on last day at work (23rd dec) one pump stopped working - i think it was frozen - so put the van away since them with a heater in the back, turned up quite high.
today neither pump works - the van has constantly be well above freezing and even warm at times - i haven't turned the heater off.

i have disconnected the hoses and the water flows great into the pumps but not through them - i have also checked for air and that seems fine.

both pumps make a whirring noise so i assume all fuses are good.

any ideas / help appreciated

thanks
rob

I had a pump go on me over the Xmas period,    my system is an Ionics but the fault was just a fuse which I bought from halford and its its working fine again now  so may be worth checking your fuses

Is it a shurflo pump if so could possible be the pressure switches.
If so only costs a couple of quid from maplins.
Bypass the pressure switch go test them

thanks for your help guys

strange thing is why both pumps ?


i will have another look tomorrow in day light

[mark dew]

try tapping them with a hammer.

[anderclean]

just on the off chance there was another possible solution to try,

i've tried and done all suggested remedies and no good.

the pumps are only about 3 and 6 months old - so if i can't sought it i'll be back to the supplier asap..

(like i said - funny thing is it's both pumps, not just one - you'd think
it'd be some thing simple like a fuse - but they're all good.)

any other suggestions ?!

thanks
rob

take your pump off your tank and let it thaw out.....its likley to be frozen

[Frankybadboy]

alrite rob im having the same problem too keep me posted if you come up with anyfin?? mine doesnt even seem to be making a whirring noise!!

We have that problem one or 2 times a year and not exactly sure why. 

We've now learnt (the hard way) that if we turn on the release valve, it releases pressure somewhere in the system and it runs fine again.

Our sytem - 650 litre tank which has purified water (previously held in a 1000 litre tank in our workshop, which goes through a merlin purifier first takes about 10 hours to fill the 1000 litre tank, but only about 6 minutes to transfer to the 650l) - pumped by 12v battery though a 100psi pump, through a DI tank and before the water goes to the 2 sets of hoses & brushes we have a valve which can reduce the pressure if too much water comes out of the brush jets - there never is too much pressure as we have 2 men working off the one pump. When the valve is opened the pressure is released, and the excess water is put back into the tank. Anyway, the valve has also proved useful a couple of times in sorting out the broken pump problem. Before we learnt that we tried changing the battery, cleaning up all electrical points, switches, clearing hoses etc.

May not be relevant, but thought I'd throw in my 2 bob's worth.

Cheers
