When we are mounting to the deck, I use cut-off PVC piping to create stanchions, and reinforce the downward grade, off the service platform. Thats why we call it a gravity drain because as long as we have the necessary 1/8 inch of downward slope for every 12 inches of carry, gravity will do all the work and pull the condensate waste to the ground all by itself. We cannot have condensate runoff drain to public walkways and driveways. Our recommended books about building & mechanical systems design, inspection, problem diagnosis, and repair, and about indoor environment and IAQ testing, diagnosis, and cleanup are at the.

Condensate waste and drain line size shall not be less than 3/4-inch (19.1 mm) internal diameter and shall not decrease in size from the drain pan connection to the place of condensate disposal. So, if we are supposed to drain the primary into the drainage system of the house, can we terminate the drain line over a gutter and let the water fall into the gutter, where it will continue to the ground to an approved area? This would allow me to run from the hall where the unit and 11' ceiling is to areas where the ceiling is 10' and continue to where drain terminates. what is connection from the evaporator condensate pan to the pvc drain line and what is the material required?

Federal Register :: Hazardous Materials: Adoption of Miscellaneous 310.1 Condensate Drains: Understanding the Codes You'd fix that by either having your plumber install an appliance wye in the standpipe (I show a typical one - the Canplas 212321W Appliance Wye - as widely sold including at Amazon - below) or by pumping your condensate to another drain destination. This article discusses the requirements, or lack thereof, for insulation on condensate drain piping used to dispose of water condensate from air conditioning, heat pump and refrigeration or dehumidifier systems.
