We don't save this data. Most of my vents are through comp shingles or cedar shakes. That's kind of sad. Terry , Jun 30, If it does NOT have an individual vent, then 18' is 12' too far. If it DOES have a vent within 6' of the trap, then you can go as far as you have to to reach the sewer connection. That is why we would have to know HOW you are routing the piping, before we can give an answer. Your plumbing inspector is completely useless and must be the brother of the mayor, because if he does NOT know what is permitted, how can he possibly tell if ANY installation is proper?
Last edited: Jul 2, California uses the UPC Plumbing code. That is not the same as a contractors test. The State keeps track of time on the job before a test can be taken. The minimum is 6, before the test can be taken. If you had half that time working with a "real" plumber, then you would be getting closer to understanding what we have been saying.
Right now, it's like discussing plumbing with the hack that stocks the Home Depot plumbing department. They think that because the stand in front of plumbing parts, that it qualifies them as a plumber. I sat in front of the teacher in school, but was considered a "student". The teacher had teaching credentials. Help me out here. Who is a teacher on the site that can tell us what has to be done before you get your own classroom.
The Dry Venting Toilet If the toilet has a 3- inch waste pipe , the vent must be located within 6 feet of the toilet trap; the distance is 10 feet for 4- inch pipe. Plumbers usually use 2 - inch pipe for this, which is larger than the plumbing code requires.
Every fixture is required to have an internal or external trap; double trapping is prohibited by plumbing codes due to its susceptibility to clogging. Every plumbing fixture must also have an attached vent. The top of stacks must be vented too, via a stack vent , which is sometimes called a stink pipe.
Most houses have more than one toilet , and if they are on the same side of the house, their waste lines can usually tie into the same stack. If they are on opposite sides, however, each may need its own stack. Since the stacks must be vented , this would mean two vent openings on the roof.
As a horizontal branch 3 " is good for 20 DFU's or 4 bathroom groups. A six- unit trap is a 3" trap. Your shower uses a 2" 4- unit trap. Definition of plumbing fixture.
