2006 Upc 908.4 - Plumbing Zone

PlumberDave · 02-19-2009, 02:02 AM

In the 2006 UPC venting p.129 section 908.4
Bathroom wet venting.

What does this mean I can do now that I couldn't do before.

off a w/c 2" vert vent I can drop a lav drain if the lav has vent?

In my code book, UPC, yes you can as long as the toilet connection to the main is a wye/combe, or when using a lowheal 90. Wet venting is allowed so long as your one pipe size larger the the fixture to be attached, and limited to the floor which it connects. Vent for lav is also vent for the toilet.

IPC won't let you use the low heal ellbow under a W/C but you can use a side out ell? Who writes this crap?

I wish it was be to write the codes.

If you could get your hands on a copy of the 2006 Illustrated Uniform Plumbing Code, I believe there is a diagram explaining this section. It's easier to understand when you can see it.

I just looked in my 2003 illustrated training manual, nothing, I was gonna post it if I had it

Gonna get the 2006 soon!

2006 illustrated doesn't cover the new bathroom wet venting only the regular wet venting. its just hard for me to understand. But the good news is the inspector passed it. GC said inspector was on site 5 min made reference to my wet vent and gone.

Here is a another wet vent setup, Min shower drain is 2" min vent for that shower is 1-1/2", using a wye combo to pick up the vent for the shower, increase that vent to 2", you can now tie a lav into that vent of the shower if the sink is next to the shower.

the way I understand it, with the 2006 upc you can but prior it is not allowed.

my issue was the vent I tied onto turned horz before the branch where before I couldn't do that.
