Sorry its me again, Having faied to get a replacement filter housing I decided to just replace the pipe inside the tank for the time being so as to have a tap working, I spent the whole evening trying to get the water up, occassionaly the pressure bottle would fill but when the taps were opened this drained and refused to refill, even though the pump was working. Do you think it is just a weak pump not having enough suck to get the water or could it be the water draining back or lastly, is it just a matter of getting all the air out of the system.

What I do not understand is that if i remove the pipe from the tank to the inlet side of the pump, no water is coming out, I would have thought this at least would be full, this is why i wonder if it is just draining back and the pump is on its last legs.
I think the original filter housing had some sort of one way valve on it, perhaps this is to stop the water going back
Any thoughts would be appreciated, i am getting just a little 'tense'
regards
David

Hi,

Do you know what sort of pump you have as diaphragm pumps are quite robust at self priming (with or without a foot valve. aka - non return valve). However is you have an inline centrifugal, they do work best with a foot valve as Merlin has pointed out. When pushing the pickup pipe in to the tank, are you sure its not curving back up out of the water? If you have had the plumbing apart, are you sure you haven’t got the two pipes on the pump mixed up – easily done. As a starter, get a bucket of water and run a pair of pipes from the pump into the bucket to make sure the pump is actually working, plus it will clearly identify which is the inlet and outlet ports of the pump. Once you’ve established the pump is working and which port is what, it should all be plain sailing.

With regards to your filter, send me a pickie and I’ll have a look around for you.
