My amtrol model wx-203 tank is banging when the pressure control valve cuts out.
The cut in pressure is set at 40 psi
The cut out pressure is set at 60 psi
Is the tank bad? Or is there a repair for it.

Sounds like the bladder ruptured. If that's the casecthe ntank must be replaced, there is no repair.
There are several ways to test a bladder pressure tank. (1) Open the snifter valve on top of the tank. If water comes out tank's faulty, **OR** (2) Take a metal object and start at the bottom of the tank and start tapping. You should hear a "clunk" until you get about half way up the tank. Then you should hear a "clank".
If you hear the same noise all the way up the tank then it's faulty.
In both cases if it fails (1) and(2) the tank must be replaced. Good luck, Tom
