Hello all,
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 comes out.
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?
Thanks!
Ernesto
