It takes a few minutes for my tankless water heater to warm up, so we end up wasting a lot of water in our shower. Is there a way to avoid this? A friend mentioned a “comfort valve” or something? What is it and how does it work? Or is there another solution? Thx!
The whole town’s got bad pressure. I’m thinking of pulling in water throughout the day so we’d have enough during peak times, like a big toilet reservoir.
