Welcome to our forum.
We've had all kinds of trouble with Waterway pumps that we bought from hottubwarehouse. They were very helpful in shipping me replacements and didn't even make me go through the hassle of returning the busted ones. The latest batch we got from them seems to be crapping out again and since we live in Boston and had some freezing while we were away, I'm thinking about just going with two new pumps. The one thing I noticed about the different pumps they sent me is the manufacturer of the motor seemed to change over time, and the issues we had were always with the motor and not the pump itself(We had one motor make a loud clanging noise and seize up and trip our breaker when we 1st fired it up. Do different resellers combine the pumps with different brands of motors? If so, are there ones that I should be looking out for?The motor/pump in question is a Waterway 3721621-1D with a 4HP, 56 Frame, 2 speed, 12/4.4 motor.TIA for any advice. We are about to have a few days over freezing here so I'm really hopeful I can get the tub back online.-ed
