Customer Reviews


1/6 HP Cast Iron 3-Piece Oil-Lubricated Booster Hot Water Circulator Pump is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from The first pump we received was improperly cast and the outlet was filled with solid cast metal up inside the housing. As it could not be seen, this was not discovered until after it was installed and wouldn't pump anything. Grainger got us a replacement the next day and it worked fine. B&G should never have allowed this to leave their factory this way. Obviously, they don't test the pumps.
