In response to Re: Tub drain

: Our tub drain is set up on a 1 1/2 line that runs for about 5 feet before tying in to the vent. This vent is 1 1/2 which goes up into the attic and ties into the main vent stack. The shower drain, a 2 inch line also utilizes this vent and is within 2.5 feet. I noticed that the max trap arm to vent for a 1 1/2 line is supposed to be 3' 6 inches. Ours is 1.5 feet longer, and since the tub sits somewhat away from the walls left us with no choice. Will this work and what if any are the drawbacks of this set-up? Is siphoning going to be a big problem..P.S. This tub will not see much use! TIA

Shelly,
Siphoning would be the problem. If water remains in the trap, then you are okay. Terry
