Does that mean that all fixtures are now double trapped in violation of IPC 1002.1jar546 said:Outside is a building trap with a fresh air intake required by the local sanitary authority
Its a fresh air intake. If it was on the other side of the trap, it would be venting the sewer system gas. There is an exception to IPC 1002.1pwood said:isn't it usually trap then vent in the direction of flow? i'm going back to the state of confusion now.
I have never seen a building trap before. What "local conditions" would nessitate the need of one? Jar stated it was a local ammendment requirement which is fine but what was the reason for it? Anyone care to educate me when a building trap may be needed? How would I know when to approve one to be installed?jar546 said:Its a fresh air intake.
