Agree on the recirc pumps as well - fresh water is one of our most precious commodities, running it down the drain while waiting for the hot water to show up is pure waste.
Happy to go into more details if anyone wants....

As a contractor who build all sort of weird siht for people, I must ask how much benefit, where and when is the return in investment for my clients?
I forgot to add this:
Not busting your chops here, but knowing is one thing, but at what cost. As far as recirc. pumps are concern, I advise against it at times (talking myself out of a job) because the financial benefit does not add up. I can't suggest tearing out walls, installation return pipes, running electrical then buttoning everything just to speed up the delivery of hot water. I wouldn't do that to people. They can wait another 30 seconds for that hot water. It not worth $1000 bucks of work. if they are doing a full remodel, then I would suggest it for sure.
