    Taco, recirulation pump 003-PNP

    Attached is an instruction sheet, and submittal data information for the Taco, 003 plumb & Plug, with a timer, and 6 ft pig tail to facilitate wiring. The instruction sheet has a diagram of a typical piping layout.

    hot water recirc

    When you pipe a hot water recirc you must put a check valve on cold water inlet, I usually use a taco 006 bronze circulator and wire it with out an aquastat so the circulator runs continuously. some guys like to use an aquastat. it has been a while since i have done one the only other thing is an expansion tank i was told to always put one in but recently a contractor friend told me you dont need one the water heater acts as the expansion tank. hope i could help

    Ummm

    The only way that water heater will help alleviate expansion is to leave it shut off. Your contractor friend's advice is bad.

    Try...

    ...www.gothotwater.com . You don't need a separate recirc line at all.

    Expansion tank

    Oh it (water heater) will act as an expansion tank alright. As it crushes the flue pipe.

    I suspect what you friend meant was the well trol tank may act as an expension tank?
    If you are on a well system and there are no checks between the well tank and HW tank.
