We recently launched our new-to-us 1982 Hunter
33 and are having problems with the water
pressure pump. If we turn on the breaker, the pump starts to run but doesn't seem to build up any pressure. We've tried opening one faucet, two, or all at the same time. No water
Other things we've tried:
- Disconnected the pump's intake and blew really hard into it. My wife confirmed that bubbles come out from the pick up pipe in the tank (which, BTW, is full). So we assumed there're no blockages in that line.
- Placed thumb in pump's intake while running. I expected to feel some suction on the thumb, but nothing at all. I'm not sure this is a valid test, though. Is it?
- Dissassembled the pump and made sure it was clean. I've never seen the insides of a diaphragm
pump, so I can't really tell if everything is in good working order.
- After re-assembly, I blew into both ends of the pump and wasn't able to get any air through. Can I assume that means there's no leaks
in the pump?
We're going to get a rebuild
kit, but we're really not sure that's the problem. One thing we should've done is to make sure there's no air leaks
downstream of the pump.
Another piece of information you may find useful is that the pump also feeds a water heater. The line coming out of the pump goes to the faucet in the head
, the faucet in the galley
, and the water heater.
For the extra curious, the pump is a SHURflo PRO Blaster, built in Sep/2000.
Can I get an education, please?
