Default Pressure tank loosing pressure

Ok great lakers

House is ten years old. The shallow well submersible pump is short-cycling because the pressure tank is loosing pressure. Here is what I know:

The tank's pressure is correct
The pressure switch is functioning correctly
No leaks in the house. No leaks in the copper.
There is NOT a check valve right where the water supply enters the building.
I am assuming there is one somewhere I cannot get to without pulling the well pump.

I'm guessing the water or air is flowing back into the well.
Is my tank bad or the check valve on the well side bad?

I would look at installing a check valve 1st. How big is your well? 2'' or 4''?

Also, Try isolating different parts of the system. After we went for a 2'' to a 4'' well, with a new pump and tank, we noticed that they well was kicking on when there had been no water running. Knowing all the piping, valves ect were new, we started isolating different parts of the house, and found a leak in the wall at the shower.

Nick, are you saying that if I install a check valve that will fix my issue, pending there are no leaks at any part of the system? (Shower, sinks, etc. )

If the leak is between the tank and the pump, a properly seating check valve will stop it. Also, make sure you have enough air in the tank.

Logic would say so. I'm not a plumber, but I've stayed at a Holiday in express a few times. Unless H aggar's idea the case, then your fawked. With where you're at, it wouldn't terribly surprise me. IIRC, you have a really high iron level in your water, so if it rusted something off, you may be SOL. Give Gonyon's a call. They are the ones who did my well. They are Duck Lake and Whitehall, and have the best price with in the 4 counties (Muskegon/Ottawa/Kent/Oceana when I priced it out before I had them drop a 4'' at my place. You may have a replaceable point also, so that's worth looking into. When you bought the place, did you get any info about who dropped the well? If not you can call the county and get the well permit info.

My pump has a flap valve on it, every now and then it doesn't seat just right and the pressure drops in the tank. The problem basically fixes itself, however if I ever start droping pressure on a regular basis, that will be the fist place I will look

Haggar, since I still have outstanding water pressure does that point to something like a valve and not a drop pipe?

Thanks for the help people

Hancho, unfortunately I cannot look at my pump because it is in the ground

Flap valve and check valve are essentially the same thing, correct? I get the mechanism is different, but the purpose served is the same.

Flap valve is a check valve. Any valve designed to only allow flow in one direction is a check valve, though there are various designs.

Watch part 7 and 8 on this youtube channel.... The check valve is down by the pump. If you don't want to do it yourself, you may need to call out a well company.

Start by determining which side of the tank it's leaking from (inlet/discharge) and go from there. If it's leaking on the inlet side, a check valve just before the tank will fix it, but that also indicates a problem somewhere between the tank and pump. Judging by what you have said, I would guess it's just a check valve by your pump that isn't seating correctly if on the inlet side. If it's on the discharge side, things could get interesting.

Here ya go Aaron... watch this. It's a compliation.

This is what I would do.

1. You need to figure out where you leaking. Allow your system to pressurize, then shut of the supply line between the pump and the pressure tank. Wait a bit. If you still have pressure in your house, you leak is between the pump and the tank. If not, you're going to find a mess in your wall somewhere.

2. I have a feeling, it's between the pump and the tank. Either DIY, or call Gonyon's to come out and fix it..

If the check valve by the pump is not restricting flow you don't need to replace it. A check valve anywhere along the supply pipe will do the trick.

I disagree... If the check valve on the pump is bad, it' is essentially back flushing the well point ever time it shuts off with water from from the check valve to the pump. I'm not an expert, but if left doing that long enough, it would create a sink hole. Wasn't there a guy on here who had a sub surface leak that eroded his whole foundation?

Regardless, as it is now, if I understand, assuming it's the check valve at the pump right now, his pressure tank is power back flushing his well, and that's really not a good thing.

Yes, same thing...and my pump is also in the ground hence me not fixing the problem as of yet...I consider myself on borrowed time with this thing, lucky it rarely happens

A check valve by the pump will keep the water from back flushing.

Edit: A check valve by the tank will prevent back flow, assuming all supply piping is intact.
