The Viper Pan & Drain Treatment is a good replacement for pan tabs because it won’t clog the drain when it gets flushed out with natural condensate. It uses natural enzymes to break down sludge and other nasty growth in the drain. We like to spray it in the pan and on the first row of the evaporator coil. It’s also safe and smells nice, which may make it an attractive option to customers.
