My home has a well with a submersible pump. It has been running every

the check valve (the check value is down about 60' near the pump)?

It sounds like you have two problems.

A leak somewhere.

A tank that is almost totally water logged.

You need to replace the gauge first to really tell what is happening.
They are not expensive.

Even with a leak, the pump should run for a significant time before it
shuts off. Rapid on/off cycling is almost always a sign of a tank with
insufficient pre-charge.

The pump still runs every 2-3 minutes even with the supply to the house
shut off so the problem is the tank or a leak. The pump runs the same
amount of time as it did when the system had no problem - I would think
it would have to run longer if there was a leak (?). Could I replace
the tank myself - it's too small for our system anyway.
