FBC Mechanical 307.2.4.1
Posted: Sun Jun 10, 2018 7:18 pm
Hi-wall mini-split indoor units use tubing to gravity feed condensate outdoors with pitch per their IOMs. They do not have to overcome static and several mfgs I checked do not mention inline check valves or ptraps as required by 307.2.4.1, let alone require one. FBC copies ICC so what was ICC thinking when they inserted this section? Now that it is part of the code, an inspector is requiring one or the other despite arguments that mfgs do not want either installed on their hi-wall unit drains. Higher static duct models and cassettes come with a condensate pump so not required. What are your thoughts? Thanks, Greg Hatfield
