3' up is a long way. That's equivalent to -1.3 psi. The way I figured out I had a suction leak was... after I put an inline strainer (with a clear bowl) on the pump, I would see bubbles that never completely cleared up. Maybe you can put something clear, ahead of your pump so you can see for sure if it's an air leak. Craig
Actually, the line into the water pump from the freshwater tank was clear enough that I could see the steady march of bubbles. That's what tipped me off that I had an air leak on the supply side in the first place. Put the new strainer on yesterday, and no more air in the line. So all is good. As for the 2 or 3 foot rise, I also turned the flow/pressure adjustment on the water pump up a quarter turn when I had it out on the bench, which improved the flow a bit. Only downside of that is that it seems that the pump runs a bit louder than before, which is certainly livable. All is well, and we're ready to head out to Cape Cod and Vermont this coming weekend.
