Why would there be a check valve on the cold inlet?
Some have used a check valve on cold inlet......allows cold water to enter but prevents hot from backflowing into cold.
Lots of configurations .........different ideas/reasons
1 valve systems, 2 valve, 3 valve, 1 check valve, 2 check valves, NO check valves
Sorta like 6 of one/half a dozen of other :B
