Never Freezes - Never “Dries” Out!

The Air-Trap™ allows liquid condensate to drain from the HVAC equipment and simultaneously prevents air from entering or escaping from the equipment.

Typically, HVAC equipment is fitted with “P” traps that require water, or another liquid, within a standpipe to prevent gas from entering or leaving the unit. As a result, the “P” traps are susceptible to freezing - expansion - bursting. At other times, the traps dry out allowing gas to escape or enter the HVAC equipment. The Air-Trap™ never requires addition of water to prevent unwanted air leakage.

Worked perfectly!

My old p-trap broke and it took me a while to dig it out of the ground. I didn't want to buy the parts to replace it, so I searched for a better solution. I found the waterless trap. It arrived quickly, and it fit perfectly on the original pipe, which was great. I turned on the A/C and gave it a try. The little red ball stopped air from entering my system, and when the unit shut off, the little red ball released and the condensation water started running out the end of the valve just like it was supposed to do. I was thrilled! If your old p-trap is broken, this is your perfect replacement. No more burying pipes in the ground, and it really does work perfectly.

Simple and brilliant

This concept is new to me, but makes sense on all levels. I plan on using these for installations and service calls.

DO NOT SHIP UPS

Hello from Canada, it is a common practoce to ship UPS to Canada even though your web site says ship USPS. Please ship USPS, UPS is a rip off company when shipping to CANADA, they charged me a $35 brokerage fee on a tax free $50 item. This has happened twice before after which if i had no choice i would self brokerage my items. UPS is the only shipping company I know that charges way too much , compared to other companies that charge a fare amoumt if anything. Just for the record, UPS has a bad reputation for doing this for items shipped to CANADA. AGAIN, If you do ship UPS to Canada in the future i will send it back and never buy from your company again , simple as that. Tired if getting Ripped off from UPS, please use USPS instead as you advertise.

Leaking junction but great idea

Before installing this device in my home, I wanted to test it, especially for the slope and was very impressed to see the ball remaining in place at quite a steep angle. Now, the problem is that the junction where the O-ring is does not close properly and water leaks from here if not 100% super aligned. This is a design flaw which needs to be addressed as you don't want a leak in your garage from an AC drain in South Florida weather!

Thank you for your feedback. The O-ring seal you mentioned in your review has been addressed, so it is no longer an issue. We always appreciate feedback from the field.
