Drain - Plus

A drain solution DESIGNED for HVAC condensate lines!

About Us

Drain-Plus was originally founded in 1990.  Since it’s inception, we have worked to gain a patent and develop a mass production project.  Prototypes of Drain-Plus have been in working conditions for years without failure.

In 2005 a mass production project was put in motion and we are now excited to bring to you the best Drain-Plus has to offer.  The Model 1600 (Supco part number DP34) is produced through injection molding and is hand assembled to ensure quality and superior workmanship.

We believe Drain-Plus to be the most effective condensate drain for draw through (negative-pressure) HVAC systems on the market.  Drain-Plus allows maintenance free operation from season-to-season with no worry of “dry-trap” syndrome effects or conditions.
