Float Valves and high pressure problems

Assuming the tank that's overflowing is hot water, the easiest way to find it is to run all the pumps on soap until the check valves are hot to the touch, then turn them off and turn on the weep. Whichever one/ones is/are leaking back will get cold. You can do one or two bays at a time - I'm usually at the wash late enough that I can tie off all the guns and check them all at once.
 
Another thing maby is, It's getting warmer now. At night turn the weep on to just one bay. It might take a couple of days, depending on how many bays you have. And you'll be spending some weep water which might seem like for nothing. But when you go to rip things apart, you'll know it's for a good cause.
 
A friend of mine had the same problem eons ago. The equipment manufacture that made his equipment used cheap brass check valves on everything that required a check valve. He was also getting weep water back into the main supply tank and into the Presoak tank. He disconnected the weep line and started the pump and had water coming out 2 of the 5 weep check valves. He replaced all of the check valves with stainless steel valve checks, no problems since.
