I have two questions:
1) I have a 2†tub drain that runs 6.5 feet into a 3†wye from a toilet. The two descend at 45 degrees, 18 inches to the stack.
Since I gone up one size from a 1.5 " tub drain, am I allowed longer than 60 inches for this drain?
2 – My local bath supplier has sold me 2- ¾ inch shut off valves in order to connect the water supply to a ½ tub spout. The reason for this is that we want to use the same trim handles as the rest of the bathroom and we don’t want to use a shower valve for our wall mount tub spout (ugly). We have the plumber’s opinion that this cannot be done. That if we flush the toilet we can end up with back flow of hot water into the toilet. Our local bath shop that sold the valve – says that this cannot happen and that before modern mixers existed that this is the way all bath tubs were connected.
Can I hook it up without backflow protection in the valve??
