Frequently Asked Questions

Q. "What is UL Listing?"
A. The Underwriters Laboratory was once an insurance industry organization, but currently it is a non-profit organization and tests electrical components and other equipment for potential hazards. UL is the trusted source across the globe for product compliance.

Q. "What size of discharge tubing do I need for the Zoeller #521-0001 condensate pump?"
A. The manufacturer recommends 3/8" I.D.(inside diameter) flexible tubing. Do not use flexible tubing larger than 3/8" I.D. A hose clamp (sold separately) is also recommended.

Q. "What does it mean when it states 18' shut off head? "
A.It means the pump will not move water beyond that point in height. If the pump shut off height is 18 feet and you put a pipe 17 feet 11 inches high straight up from the pump, water would still trickle over and out of the pipe. If you put a pipe at 18' straight up from the pump, while the pump continues to operate, water will just stay at that height in the pipe.
