no the code says you may go horizontal under flood rim if it is unfeasible to do otherwise but graded to drain and you must use drain fittings

That is exactly how we ran them In NM had to be a 45 at the top no horizontal. Here in Tn we use those air admittance valves like crazy I hate em btw the little black ones at HD dont work if your gonna use one do yourself a favor get a good one from the supply house......still no gaurentees

The black ones are not code approved here but just last week was in supply house and this plumber guy, ( I assume ) picked up a few drainage fittings and specifically asked for the black one. Tisk, tisk.

I read all the posts and looked at VA code and still am perplexed. None of the diagrams state if the horizontal vent pipe under the floor has a limited maximum length. Reading the code it seems to imply that it is 6' for 1.5" pipe and 8' for 2" pipe. Or it could be read to be for the waste pipe to vent length. Does anyone know if the horizontal vent pipe length matters?

I work in nova, why don't you use a studder vent instead of a loop vent? The distance won't matter If you use a studder vent. Using the loop vent vent I believe you are required to follow the maximum lengths you posted( 1.5 6', 2" 8')

In rhode island we are allowed to use aav's. The other way you are describing is what is known as a bowe vent.
