Comapatibility with dedicated hot water recirculation plumbing
Looking at the pump here and at a Lowes store, I would have to say yes to your question. I see nothing on that pump that forces you to install it on the tanks discharge or under a sink, per instructions.
I have a re-circulation loop I installed in my home. I brought a dedicated 1/2&quot; line from the 3 bathrooms in my home. I soldered in a &quot;Tee&quot; and brought all 3 dedicated lines back to the hot water tank. After each tee I added a check valve to each line to stop any back feed through that line. All 3 lines were collected into a 3/4&quot; copper line that went to the smallest B&amp;G pump I could find (38 watts) and connected it to the tank at the bottom drain. I added a cheap timer so the pump runs 15 minutes per hour, except at certain times when more hot water is needed for things like showers and turn it off at night.  Hope this helps.
