Hello All,
I am in the planning stages of updating a 5' x 5' bathroom built in 1930. One issue I'm studying is the toilet sewer pipe.
Presently, the toilet has a 16 inch rough in. A wall tank is connected to the pot with a 2" chrome L. I want to make it a 12 inch rough in and it seems easy enough if I cut the 4" cast pipe in the right place, use a 45 , i can swing the pipe to the other side of the floor joist plus a couple more inches. The toilet, tub and bathroom sink are the only fixtures on this 4" pipe that runs about 20 ft before going below ground.
My three questions are:
1) The current set up has a wye with a clean out. Do I need to install a clean out?
2) Would it be bad not to? If I do, the 45 will angle the clean out deeper into crawl space. so a person would have to climb into the crawl space to run a snake thru. I'm thinking it is better to have and never use than not have and someday need.
3) With modern toilets, would it be better to reduce the sewer pipe to 3" near the toilet or leave 4" all the way to the toilet?
I would appreciate all feed back. Thanks!
