I installed one last fall to replace a dead PAR. I've read poor reviews of Jabsco pumps, but it was onboard, new in the box. I didn't try it until spring, when I refilled my tanks. It leaked. I tightened the fittings and clamps. It leaked. Tightened again, broke the outlet port. Bought a new port, reassembled, it leaked. Looking carefully, I see that the leak is from the pressure switch. Removed, tightened, reinstalled. It leaks. Removed, tightened the bottomplate screws. Reinstalled, no leak! I don't know how well the pump will last, but I'm not encouraged by the lax assembly procedure.
