Cannot believe I am excited by a pump but I am. This is a real beast with incredible power yet surprisingly quiet. Great price and excellent service from Plumbworld. Tour De force with my new
Mira Agile Sense ERD+ also from Plumbworld. Thanks.

Needed to replace pump, only 2 1/2 years old with, I suspect, a U/S PCB. Expensive kit to fail after only 2 1/2 years but Grundfoss will apparently service items less than 5 years old. Yet to see how good that service is. As far as PlumbWorld is concerned, they provided great delivery at the best price on the Net.
