Efficient pump
By Happtech (from Littleton Colorado) on 4/6/2011
"This pump replaces a pump with a mechanical seal. The seal on the old pump normally failed on the coldest day of winter. The new pump arrived on time, and was easy to install, even though the installation directions were somewhat vague. Orientating the pump for proper positioning of the electrical junction box was easy. The new pump ran perfectly right out of the box. It made a gurgle or two until water reached the insides of the pump bearings,(The bearings are lubricated by the pumped media) and hasn't made a noise since. This pump is half the size of the replacement, and works better. I would have given this pump five stars if the installation instructions had been clear."

Very happy
By Verified Buyer (from Seattle, WA) on 11/10/2015
Lost my circ pump so I had no heat. Did an overnight on this pump. Arrived with no issues. It was slightly different than the original due to the location of junction box but it fit. Came with gaskets. Simple job. isolate, unwire, unbolt and slap the new one in. its quite. Price was right when I shopped around. I think this is the second time I have dealt with this company. I would do business again
