I would say thatthe answer to your question depends on how your plumbing trunk lines were run, but..
- itshould be as simple as installing the valve at the furthest location from the water heater.
- This way, hot water will run through the trunk lines anytime the pump is activated -- running past each of the closer locations and resulting in short wait times for hot water anywhere.
- You will also not waste any water during the wait.
I recently installed this type of pump as part of a green remodel/addition to a one-story home in Winter Park, FL.
We created a split plan, by adding a master suite to the far side of the home (furthest from the existing baths).This resulted in a long wait time for hot water and the hot water recirculating pump resolved the issue.
I hope this helps.
