Running a separate return pipe would be a lot of work and unlike the

other brands you all told me about, this one does't run all the time and

doesn't run on a timer or a schedule.



It just runs when someone pushes a button. Then it says it runs until

the water is hot (98^ iirc), forcing the previously hot water back

thought the cold water pipe. Since I'm concerned about the bathroom

sink, the button would be at t he sink, maybe at the side of the cabinet

under the sink.



I don't have a schedule either, I wish I did, but I get up at all hours

and go to sleep at all hours and wash my hands in that sink at times I

can't predict.



Other than the push button, instead of a timer, and that the pump is

under the sink, it's a lot like the Watts recirculator.

That is the type I described in that other long thread where this
was discussed. It has the same disadvantages as any system that
uses a pump and lacks a return line, ie tepid, crappy water from the
WH will be in the cold water line for the length of the run. For me,
if just the bathroom is on that line, then it's probably OK. If it
also serves the kitchen, then forget about it.
