In response to Re: Autocirc
I don't know that much about them, but there are other companies like
that make similar/same item.

: I am interested in the autocirc act-303-btw retrofit
: hot water recirculating pump. It works by pumping the
: hot supply into the cold, until hot water starts to show
: up and then closes the valve.


: Is there a problem uses this, because it seems to me
: you are introducing backflow on the cold line. Do you
: need some kind of backflow prevent on the branch to the
: water heater?

: Thanks
