It’s a game changer. My smart plug lost its connection while I was messing with my router one day. I had forgotten how bad it was without the pump. I’m in a warm climate so the heat gets paid for twice but I don’t even care, it’s a luxury I am willing to pay for.
Fridge water is unaffected. The last sinks where the valves are located are lukewarm for 5 seconds or so. The rest of the sinks are normal for me. I have 2 branches so 2 valves.
