That is exactly what I am going to do. I'm installing a ball valve at the top. I already have a brand new one. Thanks Gary. Shopping now for the two thermostats. Today I redid the wiring to what was in place from the factory. Replaced the breaker and the switch.I can't see any reason to tear it all out and a 3-way bypass has no advantage except maybe that manual valves don't get gummed up with mineral salts as quickly as check valves. Converting to a 2-valve bypass by adding a manual valve at the hot outlet eliminate the outlet check valve and is a cheap & easy fix to your problem.
