2" trap for tub/shower. Is it a good idea?
I am replacing all my waste lines. I would lilke a 2" trap and arm off my tub/shower instead of the 1 1/2 inch. My assumption is that a larger trap and pipe means fewer hair clogs and better/faster drain.. The trap arm runs about 2 feet to the 2" vertical abs drain line. I would use an adapter above the trap to go from for the 1 1/2 inch drain from the tub.
So I am wondering if this is bad as it will hurt the self cleaning action of the smaller diameter pipe. The tub shower is used mostly as a shower . I have read pros and cons regarding oversizing drains.
If I could find a 2" tub shoe, I would use that too..
Thanks in advance for your replies!
