Why it matters
The VCMA-15ULS is the condensate pump most HVAC installers reach for. A 1/50 HP motor moves 65 GPH at 1 ft and stops lifting at 15 ft, enough for a typical basement furnace draining up to a laundry sink or out through the rim joist.
The S in the name is the overflow detection switch: wire it to shut down the furnace or air handler (or to an alarm) if the pump fails and the 1/2 gallon tank fills. It takes condensate up to 140 F and has three 1-1/8 in inlets.
Who it's for, and who should skip it
Good fit if
- High-efficiency furnaces
- Central AC coils
- Dehumidifiers on a shelf
Look elsewhere if
- Sump pits or basement flooding
- Lifts above the maker's maximum
- Owners who won't clean it twice a year
Pros and cons
Pros
- Overflow safety switch included
- Three inlets
- Handles 140 F water
Cons
- 15 ft maximum lift
- Tubing sold separately on this version
- Wiring needed for the switch
Limitations to weigh
- Wiring the safety switch to your furnace or air handler needs basic electrical knowledge; hire a technician if unsure.
- Clean the tank, float and check valve every six months or so; algae and slime cause most condensate pump failures.
