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.

SOURCE: gould 1/2hp submergible well pump cycles on and

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,

SOURCE: jet pump - 100 '

Sounds like it could be low water, but here is a few questions to help me diagnose the problem

Is the pressure gauge showing any pressure ? If its holding at 25-30 psi and wont shut off, its probably the jet pack in the well. The jet pack has a nozzle and venturi that creates the suction to pull the water out of the well and into your house. If you pull this out of the well you have to replace the lines or else it will keep plugging up.

How old is the pump ?

What brand of pump ?

Take the cover off of the well casing and put string with a small weight on the end of it. Its easy to buy a roll of kite string and lower it into the well until it hits the bottom of the well. Mark the string when it bottoms out, then you can pull it out and see how much of the string is wet. This will tell you the water level in the well.

It could be the impeller in the pump. If this is the case, get another pump. Its not worth the time and effort to fix the old one and then have it go out on you again.

You said you primed it and it was ok ? If that's the case, it could be the check valve. This is a one way valve that lets the water up from the well, but wont let it back down into the well. To check this shut the water off to the house and see if it holds pressure. If it does not than either the check valve is bad or you have a pin hole in the line going down into the well.

I hope this helps you. Let me know if you get it fixed or need more help !

Pressure switch clicks off and on will not stop

could be several things that cause this. I would first try increasing the spread between the upper and lower limits. it they are set too close together you can get this kind of bouncing on and off. Also, how old is the switch? as they age they get less and less accurate at reading the pressure accurately and this could be the problem. Longer shot, could be a leak in the well check valve. Water leaking back down into the well and that keeps turning the pump back on when there are no faucets open.

Goulds j5s pump discharging rusty water and green moss particles. how do i flush

If its discharging all the time, I would say its sucking up contaminated water but if only occasionally, that would suggest something is rusting / deteriorating in the system and it "grows" when the pump is not in use. I would have a close look at the source tank(s), the connecting pipework and as a last resort, disconnect the pump and have a look inside the pump chamber.

When H2O runs pump keeps cycling every 15 to 20 sec. H2O drops to 30psi and pump stays on until 60psi. Then a couple of seconds does again until H2O is shut off. Pump runs for around 30 seconds.

If you've got the water turned all the way on, it sounds like your setup is operating normal. If the pump where turning of and on say every 5 seconds or so I would say to check the air pressure in the water holding tank that it's at the correct pressure.

Why does my goulds pump j5s draw water to the pump but it won't pump out, what could be wrong and can it be repaired?

you will have to prime the pump after working on the lines. You can get just the pump section but I doubt that there is much wrong other than priming the pump

Our goulds pumps j5s is running very loud after we replaced our sewage ejection pump last week. Could these problems be connected?

Those pumps last a long time. I do not think the problems are connected. I am assuming you are pumping water up from the pump. The pump has a check valve in the discharge that may not be closing. Cleaning that should solve your problem. Be sure water will pass through the discharge line into the drain.

Gould j5s, pump not going above 15 - 20 psi, does this sound like it could be a priming issue or not since it is pumping some water?

how much pressure do you want with a 15 to 20 psi, really what are you pumping house water, you need more pressure to supply a home like a 60 psi with an exterol tank

Pump will not shut off

could be worn mechanical parts in the pump, or air in the pump. Make sure there is no air leaking into the suction/inlet side of pump.

I have a pump that will not pump higher that 40 psi. There seems to have plenty of water to the inlet, it is even gravity flow no suction needed. This pump is about 9 years old and recently during a flood...

The Goulds J5S pump is only rated for 40 psi. Is it possible that is the correct operating pressure? Did you get a higher reading in the past?
