Had the pump fitted new September 2015 used maybe four times .went away first time this year two weeks ago, pump running very quietly, but no water coming through, have checked filter,no kinks in pipes, checked diaphragm, water in tank ,pipes not blocked, any ideas what the problem could be

Do you have a winter drain down valve fitted, if so has it been left open. If it has then water will running out under the van when the pump is pumping but a may take a time for that to show.

 

[Joanne55]

No bother valves are shut ,there seems to be no power to sucking the water through, hence the pump running more quieter than normal ,been on shurflo troubleshooting sites but don't seem to have my problem listed

If the pump is accessible I would suggest that you remove it and test it on a short pipe into a bucket of water and a good battery, also test by blocking off the outlet to make sure the pressure switch is doing it's job. If it performs ok then the problem lay on another part of the system. If fails to pump well then just replace it as it's out of warranty.

if you have acces to a hose try back filling open all taps conect one to a hose when you have water at all taps turn of hose but dont close taps

Remove the shower head, turn on cold tap and turn on pump.
Now suck hard on the shower hose.
Unusual for a diaphragm pump but may be air-locked.
Could also be a stuck open poppet valve in the pumps valve block allowing water back out the inlet valve.

Hi everyone tryed all your suggestions but no luck ,took pump out hooked up two pipes in a bucket of water ,there is absolutely no suction on the inlet side of the pump checked again inside the diaphragm just doesn't seem to be anything wrong ,going to order new pump and hope it solved my problem, thanks everyone for your help.

Could be you need an inline "non return valve" fixed just before the pump.We did when we changed ours.
