super saver backflow

[txheat]

Water seeping back into hp soap holding tank which dilute chemical mix. I don't see check valves on back side. I notice when I use rinse, it fill up more...but could be coincidence. Btw I already check hydrominder. Suggestions?

The check valve is in the bottom of the hot water tank. It's a 3/4" valve, there's not a separate one for soap or wax.

Thanks Mep...which one? Do they correspond to each chemical holding tank?

There's one check valve for each bay, and one of them is likely bad. If you're still running hot water, the easiest way to find which one is bad is to run each bay on soap until the valve gets hot, then turn to rinse. The bad check valve will get cold.
