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 condensate drain line slope towards its final drainage point shall be at 1/8" per foot [or, of course greater, where vertical drains are used - Ed.] OPINION: your local building code compliance inspector/officer is the final legal authority on HVAC condensate drain trap requirements.
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.
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
29 Ιαν 2023 · A condensate drain line is integral to a home's HVAC system. The drain line helps keep the interior environment comfortable by removing excess moisture from the air. It also prevents water damage if too much moisture builds up in walls, floors, and other areas.
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.
The condensate drain access point is typically located inside the home near the indoor air conditioning unit. This is identified by a small vertical vent extension as part of the piping, positioned above the point where the line exits your air handler.
