From what I can tell, both local code (IPC 2018) and the water heater install guide only say that the condensate line needs an air gap. We discuss air conditioning, heat pump & condensing boiler or furnace condensate drain leaks, locations, causes, repairs. Bottom line: The model building codes require a P-Trap on all plumbing waste lines that is connected to a sewer. Working on a school and they love high ceilings. Venting after the trap (like shown on the EZ Trap above) is an excellent idea in most applications because it helps prevent airlock that can occur due to double traps and shared drains. it is a good practice to insulate them to eliminate any chances of condensation. @Jack Mc., m), and allow primer to dry. not less than the drain on the unit, and in no case less than 3 4 of an inch (20 mm).
