Refrigeration Technologies announced the launch of Viper Drainado, a 15-in-1 adapter that connects three wet/dry vacuum hose sizes to five PVC pipe sizes, covering ¾-inch to 2-inch condensate pipes by suction or pressure. Developed by HVAC technician and inventor Christopher McConnell and licensed to Refrigeration Technologies under a multi-year agreement, Viper Drainado was built to solve a problem common to both the HVACR and plumbing industries.

Blocked condensate lines account for up to 90% of water-related air conditioning service calls, and clearing the line has historically meant improvising: Stacking multiple PVC reducers and fittings, taping the assembly to a vacuum hose, holding the joint together by hand, and scraping adhesive residue off the pipe afterward. Similar clogs are common in plumbing too, and technicians in both trades have long relied on the same makeshift fixes.

Viper Drainado is one molded part that flexes onto the pipe, seals under full vacuum, and grips tightly enough to hold on its own, hands-free. Its coverage spans the condensate and small-diameter PVC sizes common to both trades—moving debris under pressure or suction to clear sink traps, branch drains, and plumbing systems. 

Key features include:

• 15 configurations in one adapter: Three wet/dry vacuum hose sizes (1-1/4", 1-7/8", 2-1/2") to five PVC sizes (3/4", 1", 1-1/4", 1-1/2", 2");
• Compatible with Schedule 40 and Schedule 80 PVC, which share a common outside diameter;
• Fitted seal draws full vacuum suction and holds position hands-free, keeping both hands available for the rest of the job;
• Flexible thermoplastic polyester elastomer construction; tolerant of bleach, vinegar and pan treatments;
• Clears condensate lines, sink drains, branch lines and drainage systems by suction or pressure; and
• Serves HVACR and plumbing applications; designed for use with wet/dry vacuums

“Every solution that carries our label started with a technician need,” said Mike Pastorello, president and CEO of Refrigeration Technologies. Drainado is an excellent product that solves a long-standing multi-industry problem and is already backed by hundreds of 4.5- and 5-star reviews. We look forward to bringing Drainado the manufacturing consistency, wholesale distribution and trusted brand name technicians rely on, so it can reach more tradespeople and improve the way they work.”

The product joins an existing lineup tackling the same problem from different angles: The recently launched Viper EZDose™ keeps pan and drain lines clear on a schedule, while Drainado clears the ones that go too long between service. Drainado reaches Refrigeration Technologies’ wholesale distribution network in September 2026 as part of a portfolio trusted by more than 100,000 professionals worldwide.
