Help! Deep well pump pressure - again?
Please help! Without water for ten days now.... Previous thread below, but similar to GoofyMonkey's also. Had to replace previous 1hp waterAce deep well jet pump with new one (exact same pump). Been fighting with it for a week now. Well pipe 4" - two pipes into well seal. Both pipes are completely full of water. Filled pump several times completely. When I close off pressure regulator completely and start pump, pressure gauge screwed directly into pump housing goes right to 40 psi. As soon as I crack the pressure regulator vavle open, even just a tiny bit, pressure plummets to zero. By just barely opening it I am able to keep it around 15 psi while running, but I cannot tell if any water is going into galvanized displacement tank or not (tapping on it for sound doesn't help). I have air valve on top of displacement tank open so it can fill - - should I close it? Question two - would it be easier on the pump if I manually fill the displacement tank? Question three - with regulator closed should pressure be a lot higher than 40 psi? If so what could be the issue - Could the pump actually be defective? Looking for any suggestion? Thanks greatly!
Galvanized almost certainly
The pipes coming through the well seal are definitely galvanized - I can't imagine they would have changed over to poly below the seal. You're saying jet certainly shot if galvanized because of corrosion I assume? Well is minimum 35 years old and probably much older than that - - my wife bought the house in 1973 in terrible shape (money pit ever since we met ten years later!) and was built in 1950 or so... so I'm guessing they didn't even use poly back then? and I'm just as certain the previous owners never even serviced the system, as they were pretty clueless college English professor types - - haha....
I guess I can open up the well seal and check the pipes below it for material - don't seem to have much choice at this point? Any other guesses? And thanks for all your help! Would it be cheaper to have a new well dug in another location rather than servicing old well? I'm also assuming real well guy would have to check the old well to see if still providing ample water through screens, etc.?
