Goulds pump pressure problem

SOURCE: Gould Water pump Problem

sounds like cavitation in the pump due to the introduction of air. Check for leaks or cracks in the suction line so air isnt being induced into the pump.

Sounds like the injector nozzle is plugged. This nozzle is directly inside the influent line on single line jets and down in the well on two-line jets. I'm assuming you have it primed correctly. If this happened suddenly the it'd definitely the injector nozzle. It it was a gradual process over time then I would say it's either a badly worn nozzle or worn impeller.

My first thought was that of a water logged tank which causes short cycling, from your notes the tank is good (the tank may be partially water logged though) If the tank is ok and your getting short cycling (and the switch is good) I would guess your check valve down the well has failed. As the pump creates pressure then shuts off the water may be going right back down the well causing the pump to cycle again. This could also account for the poor water pressure as the check valve may be stuck slightly open allowing the system to loose pressure but only allowing a small amount of flow by when running. There could be a leak within the pumps drop-pipe and your loosing pressure through this leak. I expect you'll have to have the pump pulled.
I hope this may have helped,
Tom

You have a pressurized system using a pressure tank.This is a case of an air logged pressure tank. Meaning there is more air than water in the pressure tank. The pressure tank must hold 2/3 water and 1/3 air of its total volume. Installed at the tank is the air volume control to take care of this proportion. Should the air volume control malfunction or becomes defective, the air-water ratio is affected. And then,
the pressure tank becomes either air logged or water
logged.
SOLUTION:
1. Shut the power off, and open the discharge line
gate valve to flush the water in the pipe lines.
2. Open the drain plug of the pressure tank to empty
all the water at the pressure tank.
3. Close the drain plug, and put the power on.
4. Start the pump, and set the flow control valve 1/4
open.
5. The pump will normally run.

Yeah, if it won't shut off the pressure tank is not getting pressure to it or leaking out, first the cheapest ideas to try would be have someone turn water on when you are looking at the pressure gage, what psi is it, you want atleast 60, then, havet them turn off water, keep watching the gage for a minute see what it does if pump still runs its not building pressure so, is this a new install, or has it just started happening, if its new did you prime the pump? if you did the pressure gage may need replacing this is cheap, if that doesn't fix the problem, then you need to check your pressure tank the bladder may be worn out, so if I was you, I would also check for air leaks make sure all fittings are tight, you can take your hand and place on pump when running, turn water on to do this, or you may be able to hear air leaking, definate sign that your not building pressure so pump cant work with pressure tank, now if your bladder is still good once airleaks are fixed the bladder will build the pressure it needs then your done.
