Hot Water Recirculation

I've not used one of these, but it looks really interesting, especially in the Auto Control mode. They come in 1/2" sweat, 1/2" FNPT, and 1 1/4" Union connections. If you go with this, I would use the 1 1/4" Union connection with the appropriate adapters to you pex.

These are what we use, they've been great. We set them to 100%, or temperature controlled. Auto is not great unless you have a set schedule that doesn't change.
