    Replaced pump on a 2004 Caldera Utopia Elation model. Easy installation. Works like new. Much quieter operation. Shipping was a little slow but Caldera was responsive to e-mails/phone calls.

  4. New circulation pump

  5. Form fit and function

    Found this universal circulator pump on your site. Was little skeptical.
    Fit perfect, easy to install, no leaks, quite and working well.

    Last circulator was grinding and tripping my CB.


  6. Worked great

    Posted by Unknown on 5th Sep 2016

    The part arrived and the installation via instruction and Youtube video were excellent. The only issue is that it would not start at first. The pump needed to be primed by letting water flow for several seconds.

  7. New circ pump

    Posted by Brian on 1st Feb 2016

    Item is new and works as it should. I've bought several and will continue to buy them from here.

  8. Circulation Pump

    Posted by Michael Risinger on 5th Sep 2013

    This pump works just as well as the original, but is so quiet that I couldn't tell if it was working. The tubing for the retrofit works perfectly but the instructions do not say exactly how to use it. I had to call tech support in order to find out. Maybe the instructions could include more information about the retrofit.

  10. Worked liked a new pump should.

    Only one minor issue was....one of the connector wires had a screw down style tip on it and I needed to change it to a bayonet style connector to fit the circuit board.
