Rating : - Ball valves restrict flow- beware
This is a really good idea that's flawed in execution. The small 3 way ball valves are not "full port" and the tiny holes really restrict the flow from the pump to the water heater and then from the water heater to the rest of the system. You're better off buying full port 3 way ball valves and making your own.
