|In response to Re: Remodeling bathrooms - drain and vent question (Updated drawing)|
I am in the process of remodeling our basement. Included is a full bath.
This board is a WONDERFUL Forum of info.
I am not a licensed plumber, I have done extensive research into the subject. Including code requirements. I am NOT an expert. However I thought I might be able to help a bit.
First off, you will want to ensure that your diagram is code-acceptable. There's some areas where you may be close to the fence.
#1 As Deb indicated the maximum distance from vent to lav trap(1.5") is 42". That's correct. For 2" drain like bathtubs (in your drawing) the distance is 60". You'll want to check your measurement in that (revised) drawing to make sure
This should work.
You do not show any water closets. I am assuming they are on separate drain lines - that 4" stack by the tubs and they are also within the critical distance. (72" each for three inch drains)
#4. Also mentioned in another post - you can not have a double P - trap. It's contrary to code! For example, I read in an unrelated post on this board that someone wanted to trap a toilet. This would result in the toilet not flushing because a toilet already has an internal trap within. It just does not work that way. Could you imagine having to clean a toilet with two clogged traps???!!!
: Thanks so much for your reply. I've made a new drawing which I believe shows the changes you suggested. Can you take a look and let me know if it looks better.
: One of my concerns was that the 2" drain might not be a big enough pipe to drain all 4 fixtures. Is the 2" OK, or should I use a 3" pipe from the sewer to the lavatory double fixture fitting?
: I really appreciate the help.
: : Brian,
