Customer Reviews: Nice little pumpSeptember 5, 2010 Matthew Ginter(New York) I made a homemade hot water system off from my woodstove and needed a low gpm pump to circulate the water. This pump is exactly what I was looking for. Works perfect.

Good to get my instant hot water backApril 26, 2010 Virgil C. Cole 2 out of 2 found this review helpful
I purchased the Laing circulator pump as a replacement for the identical pump that had been in service for 20 years before the motor failed. The new pump motor and rotor attached to the old pump head. I threaded it on, bled the air out and had it running in minutes.
