Water problems (Again) (1 Viewer)

[oozzie]

Hi, Having problems with Hymer 544 (2004) water pump. Had trouble with the water emptying back into the tank previously, so bought a new Reich twin pump with NRV and also fitted a non return valve directly into the water pipe.

The water comes through the taps with good pressure most of the time, Then maybe next morning nothing so i have to go through bleeding the system again which seems to take ages.

Can anybody think of whats going wrong?

Thanks.

hya you must have a small leak in pipe or joint thats draining down over night

That would have to be a large leak I think. I have to go through whole process of filling/bleeding the system so over 10 litres to fill boiler and pipes. On checking, I don't seem to be losing any level out of the tank.

hya .. you have two new NRV so the water must be getting out of the system ..are the NRV in the tank ? i know one is on top of pump also to check is the boiler dump Vv isnt letting water out if you switch 12v at night??

I fitted the extra NRV on top of the tank before buying the new pump, then bought the new pump so only the NRV on the pump in the tank. Away in the van again this weekend so will do some more investigating!

Thanks..

You must have a pressure drop after both the nrv's. If you leave the pump switched on overnight do you ever hear it run?
I had a slight leak after the water heater that brought the pump in during the night but it was a bugger to find.

Hi @Badknee. The pump is always switched on, but never hear it running. Think I'll start having a look tomorrow and see if I can find any leaks.

Ok, so where is the pressure switch I wonder? We have in line tank- filter-pump-pressure switch-cold taps/water heater-hot taps.
My leak was just after the water heater so the pressure switch picked up the drop in pressure and fired the pump up. I wonder where yours is that doesn't bring the pump on?

I thought the pump was a non return valve type, maybe you gave the wrong pump.
In my hymer pump operated when tap switched on by microswitch.

it seems odd that you lose the contents of the boiler as well, or have I misread that, or is possibly that is all you are losing, but when you try to draw water it goes back to there first?

Best of luck I really hate odd faults like this, give me some thing properly broken every time.

hya i am sure that model hymer has micro switches on each tap so the pump only comes on when a tap is opened hence the thought must be a leak somewhere ....happy hunting

hya just had a thought after reading Davids post there is a none return Vv on side of boiler that will dump outside look under van when tap is on see if any water is coming out
