Review for: Grundfos UP26-64F Circulator Pump, 1/12HP, 115V (52722330)
"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."
