OK so I have a 1hp jet pump and a hunded foot well. I checked the wate level and it was good. I tried a new pump and foot valve and had the same poblem... the problem is that the preasure is only getting up to 30 psi. it just started happening after a years use of the pump with no previous problems. Any ideas??

Could be a leak in the suction line.

It's a plugged jet I bet. I just replaced my 1 HP pump and I had to do the jet also at the same time because of a plug... and the pump guy said not too good of an idea to mix and match pumps and jets... if a pump can't get past 30 psi it is most likely the jet.
