17 Αυγ 2020 · Minimum Condensate Drain Pipe Sizing Chart. Slope to be at least 1/8” per foot or 1 percent, that is for every 12” horizontally there must be at least an 1/8” drop vertically. Condensate drain piping to slope a minimum of 1/8″ per every 12″ horizontal Attics or Furred Spaces
24 Μαΐ 2023 · A condensate drain line is a component of an HVAC system that removes the moisture (condensate) that is generated during the cooling process. When warm air passes over the evaporator coils in the air conditioning unit, the moisture in the air condenses on the coils, creating water droplets.
The idea here is to maintain straight alignment, a uniform slope, and strap or support the drain lines at proper intervals as guided by the installation manual and code books. The Proper Interval to Support PVC drain lines. We’re required to get a strap on it every four feet.
Condensate drain lines are a vital component of your HVAC system, responsible for safely expelling excess moisture. Understanding their function and common issues can help you maintain a well-functioning system and avoid costly repairs.
The IMC dictates a 1% minimum pitch of the drain, equal to 1/8″ fall for every 12″ (foot) of horizontal run. In practice, it is safer to use 1/4″ of fall per foot to ensure proper drainage and provide some wiggle room for error.
A flexible plastic condensate drain line may be routed through building walls, ceilings, floors, at some installations such as split system wall-mounted air conditioners and heat pumps. at SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS we describe the routing, slope, and protection from damage for in-wall condensate drain lines.
