I own a country home with a deep well jet water system and captive air tank. The pump has begun to run for longer periods of time to build pressure. Previously the system would hold pressure when turned off and in-house valve was closed for a period of up to 2 months. Now the pressure begins to drop as soon as the pump turns off and goes to zero in a matter of 12 hours. There are no leaks in the house. The system has also become difficult to prime. Any suggestions on possible causes and how to troubleshoot are welcome. I suspect the captive air tank may be failing but don'y know how to troubleshoot the system.

Rhermann - hi, my last house had a well with an old style metal air tank. It started losing its air pressure as well. I had a local plumber come out and repressurize the tank once, and he suggested replacing the tank due to a faulty installation. The landlord had secured the metal tank by pouring a couple inches of concrete around the base. That caused the tank to eventually rust out just below the top of the concrete. Mine didn't lose all its pressure as fast as yours did, but it was noticeable. It certainly sounds like a bad tank or a failed gasket at a union.

We troubleshot my old tank by putting soapy water over the tank and its connections, then looked for the bubbles. I've done this when checking gas line hookups on gas ranges and on bike/cycle inner tubes. That's how we found the leak - we saw the bubbles coming up around the base of the tank where it was set in the concrete.

I ended up having a new air tank installed that used an air bladder, much like an inner tube. It allowed me to switch to a smaller tank and still have great air pressure. The tank ran me about $100 3 years ago, and the local plumber hooked it up for $50 in labor. I hope the troubleshooting info helps you some - regards! Jim D/Heathsville, VA

Sounds like your foot valve may be leaking. Do you have a shut valve on the input of your pressure tank. AFter the tank pressurizes try turning it off and see if it hold pressure. That will confirm the foot valve is leaking.
