FOR "SINGLE + FLOW TAB" OPTION: FLOW TAB HELPS PREVENT AIR CONTAMINATION AND WATER OVERFLOW DAMAGE: Over time, scum and grime in the drain pan can contaminate your breathing space with harmful and foul odors. If left untreated, the drain line can also become clogged, allowing water to overflow, and causing expensive property damage. Our Flow Tabs are an easy solution to effectively prevent the buildup of scum, grime, and drain-clogging slime in air conditioner condensate drain pans. FLOW TAB NO-CLOG TECHNOLOGY: Most pan “tablets” are hard pills that can move around the drain pan. They can clog your drainpipe or be flushed out when the drain pan fills. Flow Tabs are made with a unique GEL LOCK technology that, when wet, locks the tab gel into place. It will not move around or clog the drain. Best of all, our Flow Tab works for systems up to 3 Tons for 3 months. Find a full pack of our HVAC Guys Flow Tabs Drain Pan Treatment HERE
