Hi All:
I removed and old tub and will be installing a stand up shower approx. 3.5 feet (distance of new floor drain from old drain, 1-1/4" copper). The existing vent pipe for the old shower is 1-1/4" galv pipe that enters the floor drain pipe (into 2" black iron "Y" with an elbow) about 6 inches down from the existing (old) copper trap. My plan was to remove the old trap and run the new drain pipe from the existing Y to the new drain (with a trap of course).
My question is, will the existing vent still be effective now being 4 ft away and slightly further down slope of the drain or do I also have to move the vent pipe also? What is the general rule for distance of vent pipe from floor drain?
The house is a 50yr old New England Cape.
Thanks all.
