well pump problem


The check value is a little fatter than the other pipe and is about 4" long. It may be at the pump head. If you get pressure and it falls off, you may need to pull the pump. the foot screen could be clogged. The water in the lines and the tank is giving you water pressure, but when that is gone, the pump is clogged and is not giving you the volume needed to maintain pressure. If the filters are clean and you still have this issue, then the pump impellers are worn and the pump needs to be replaced.

What type of pressure tank do you have. The old ones have a bladder. It may be bad. Turn off the electric, shut the valve going to the house and open the drain valve. This will help reset the pressure balance in your tank. Or the tank may need to be replaced. This also could be your problem. Without being there to see what you are doing and seeing, helping is limited.

well pump problem


Is the pressure tanked charged with air correctly?

Many times the bladder in the tank fails while everything else runs well.
If you add pressure to the tank do you here bubbles?
If that happens or the air valve spits water the bladder is ripped and you are trying to pressurize water as the air reserve is gone.

The conditions for that would be short cycling of the pump and an instant lack of pressure when you use the water from the tank.

glad to so other help here. I have another question. when you replaced the pressure switch, did the water squirt out? This tube may also be clogged. You just need to check it all.

Sorry Bob, looks like you were the soloist for response to this one for a bit.
It is pretty hard to trouble shoot via a chat forum but good advice all around.

well pump problem


The check valve in a submersible pump is almost always built in to the top of the pump. There should not be any other check valve anywhere in the system.

If you can, turn the water to the house off at the pressure tank. If the pressure still drops, the problem is somewhere between the tank and the pump. Most likely a leaky check valve at the pump. The water has to go somewhere, either into the house, back down the well, a leaky underground pipe, or a puddle on the floor.

Submersible pumps come in 2 wire or 3 wire. If you only have a pressure switch, and not a control box, then you have a 2 wire pump.

If the flow out of the pump is less than it used to be, it may very well be that the screen at the pump is clogged. Mineral deposits will eventually clog it. It's also possible that the sediment has eroded the impellers away to the point that they don't work very well.

Good to have more help on this one. But if you look I already said all of this. At my house I do have a check valve at the tee between the pump and the tank...so I simply asked if they had the same thing. (easy if they did)

Do you have an amprobe? You can check if the impellers are bad (maybe) by monitoring the amps. It should be about 2.5 amps, if it drops along with your pressure drop.. adios los pumpus!

well pump problem


ok let see if I can answer all this when I replaced the presure valve it squirted a little so I replaced the tube also.the tank is a welltroll about 4ft tall and is charged at 32psi and is holding that.When I add air I hear nothing but air and when you release air no water comes out.I did the thing like you said shutting the valve to the house and opened the other the tank gurgeled alot and no presure from the open spigot ? if the pump needs replaced is their something I can rent to help pull it up? I understand without being here its hard to tell and I am thankfull for all the help.I wouldnt mind this so much but I have tankless water heaters and they need presure to come on sooooooooooo no hot water for a shower wife is hot enough to boil water though so I had better find a solution soon.I will check the amps

tie a rope to the line and pull it up with your car. Drive slowly, have someone directing you and guiding the line out the well. Or use a cumalong if you have one. A winch? A strong pair of neighbors? What ever you have available. Grainger may be a good place to buy this pump. Either way if that is what needs to be replaced, you save $1000 doing this yourself. Good luck with it all.

Without a tripod you can't use a car t opull a pump, and if you don't have instructions and the tools, you should not mess with it at all.

A check valve at the tank tee hides water leaks between the pump and the pressure tank and a leak means you get less water and pressure to the tank when the pump runs.

well pump problem


just to update this and let all who answred know. It is pump failure I had a local company come out and test it just to be sure and they said yes the pump is shot.The problem now is what I and others thought was the well in the house is not.The well is somewhere in the yard but no one knows where.Nothing is maked or sticking up the previous owner is dead and according to the well company the only way to find it would be to stat digging exploritory holes? I hope it warms around here soon I think I have had it with this well and will just hook up to city water Thanks for the help folks

If you can access the feed pipe you can measure down the pipe til it ends at the well head and get the distance from your house that the well is.

That would be easier than blindly digging.

well pump problem


they tried that but where it comes in it goes about six feet or so then bends and it wouldnt go any farther.I know thats not the end of it because I took a trencher through that area last year and then had it dug out even more for a gas line and hit nothing,so at this point they say the can guess and try digging with hopes of finding it or just make due till the ground thaws and put city water in

Just another suggestion from a well guy, If your well is burried in the yard it is probably old and is steel pipe and will also have a steel well seal on it. also too, There should be wire running out to the well they should be able to hook up a split box locator and trace them to the well....

Just some thoughts
