HVAC condensate drainage

Condensate Trap

A flexible ¾″ P-trap for HVAC and air conditioner condensate lines. It clamps on with no primer or cement, and you can squeeze it to clear a clog.

¾″ pipe or hub No primer or cement Squeeze to clear Stainless clamps Made in USA

No brush. No saw. Just squeeze.

A plugged condensate trap usually means a brush, a wet vac or a saw. This one is molded from flexible PVC, so you can squeeze it to break sediment loose, or back off two clamps and pull it out whole.

Squeeze to clear

Hand pressure breaks sediment loose and gets the line flowing

Clears without a brush

No ports to open. Squeeze the body by hand to break sediment loose and get the line flowing.

How to install

1 Dry fit

Hold the new trap up to the existing line to check the fit. Mark lines on the pipe matching both ends of the new trap.

2 Mark the cut

Measure ¾″ down from each dry fit mark and make a second mark. This is where you cut.

3 Power off

Switch off power at the HVAC unit or at the circuit breaker.

4 Cut

Use a PVC pipe cutter or hand saw to cut on the second mark at each end. Remove the old trap.

5 Deburr

Use a utility knife or deburring tool to scrape away plastic fragments and burrs.

6 Loosen and set bushings

Loosen the screw on each clamp. Remove the included bushing if you’re installing over a hub.

7 Install

Slide each end of the trap over its pipe or hub. Hand tighten each clamp with a nut driver or screwdriver.

8 Prime

Pour 3 to 6 ounces of tap water directly into the line above the trap.

9 Power on

Turn the power back on and check for leaks.

Tools: tape measure, marker, PVC pipe cutter or hand saw, utility knife or deburring tool, and a nut driver or screwdriver.

Common questions

Will it fit my condensate line?

Each end fits ¾″ PVC pipe with its bushing in, or a ¾″ hub with the bushing out, so one end can go on a hub and the other on pipe. Not sure what you have? Reach out.

How do I clear a clog?

Squeeze the body by hand to break sediment loose. If that isn’t enough, back off the clamps with a nut driver, pull the trap out whole, clean it and reinstall it on the same connections. Then prime it again, the same way you did when you installed it.

Do I need to prime it?

Yes. After you install it, pour 3 to 6 ounces of tap water into the line above the trap. The water seal keeps the system’s fan from moving air through the drain, so condensate can drain out of the pan.

Do I need glue or primer?

No. The trap clamps on with stainless steel clamps, so there’s nothing to brush on and no cure time.

Can I use it on a furnace?

Yes. It’s made for HVAC, air conditioner and furnace condensate drain lines in residential and light commercial systems.

What temperatures can it handle?

Down to -30°F, and up to 140°F for short periods.
