While it was not a necessity is was a small convenience & luxury we enjoy and worth the $200.

Here’s a clear YouTube video from Home Depot on how these things work and how to install one.
How to Install a Hot Water Recirculating System | The Home Depot - YouTube
Let’s say my kitchen sink is twenty feet from my hot water heater. My shower (and master bath sink—for easy connection, as the shower pipes are buried in the wall) is forty feet. I use the shower once a day. I use the kitchen faucet many times a day. They have separate pipes. I don’t think this gadget will heat them both. If I connect the bypass valve to the master bath water lines, my shower water will be hot in seconds, but my kitchen sink water will be as slow to heat as ever. If I connect the bypass valve to the kitchen sink water lines, I’ll get almost instant hot water in the kitchen whenever I want it quick, but the shower water will heat up slowly (once a day).
Any guidance?
