Does anyone in this group know of a way of testing the tank, i.e.,
using compressed air to pressurize the tank and leaving a gauge on it
for 24 hours or so to determine if there really is a leak.

Any ideas on testing this tank without removing it would be greatly
appreciated.

Thanks,

I am late to the party.
Two ways to test a water tank.
1st:
Fit a u tube to a port. Fill the utuibe with colored water.
Pump up the tank (such as with a bicycle tire pump) until you see a
difference in water level in the u tube of 12 inches
(that's 1/2 psi, which any water tank can handle.)
Come back later - what is the difference now?

2nd:
Empty tank. Let in some refrigerant gas.
Sniff with a refrigerant detector. They are very sensitive.
Could rent one?
