Thank you for sharing, I have a question: When we travel our water pump is normally on, will this method work if the water line is under pressure from our water pump?
Yes. This will simply circulate the water in the lines based on the temperature set. You need to have pressure in the lines, or you could start circulating air instead.
I see you turn the pump on with the switch and the thermostat turns the water off. Do you ever forget to turn the switch back off ? With the switch in the on position I would imagine the thermostat would turn the pump back on again once the water temperature drops.
That was part of the idea behind the design, so it was temperature controlled. If we are in a really cold place, I can use this to keep the pipes from freezing
@@EdwardCzajka Could this design be modified somehow to remove the need for an extra pump by simply opening a relay valve in a new hot to cold bypass line that drains by a new line to the fresh supply tank?
