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.
Q. "Do all air conditioners and boilers use condensate pumps? Do I need one for my house?"
A. No, not all air conditioning units use condensate pumps. This type of pump is typically used with units installed in areas where the condensation cannot naturally drain from the air conditioner. For instance, some apartment buildings or office complexes might have an air conditioning unit installed between stories. You don't want the condensation draining out through the walls or floors and causing water damage, so a condensate pump and basin is used to collect that water and pump it to a more appropriate drainage point. If your air conditioning unit is installed on the ground, on your roof, or somewhere else where any condensation produced can drip off naturally, you don't need a condensate pump. However, if you are uncertain about where you air conditioner drains, we suggest you contact your local HVAC or plumbing professional to help you determine whether or not you need a condensate pump.
