Drain Pipe Hvac Condensate Drain Line Design

Uniform mechanical code section 310 0 310 1 condensate disposal.

Drain pipe hvac condensate drain line design.

Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks. Condensate overflow due to a blocked drain may be caught by an overflow pan beneath the air. This biological growth may migrate into the condensate drain line or the drain trap and form a blockage. Three quarters of an inch is sufficient for up to 20 tons according to the imc unless the drain outlet size is larger than in ch use t able 307 2 2 for condensate pipe sizing.

This will kill any algae mold or mildew that has formed in the pipe. Just pour a cup of bleach in the drain line s access opening near the indoor air conditioning unit. Https amzn to 2l7yu3c if your looking to reroute your hvac drain line for an ac condensate drain pipe these pre design ideas may be what your looking for. If the condensate drain line is clogged you will need to use a wet dry vacuum or a special pump to unclog the line.
