Attic Remodel-No Plumbing, Best Way to Add DWV
I am adding two bathrooms upstairs in my attic. Anyone know best approach to add waste stack 3" to a 2nd floor where no waste line currently exists? All bathrooms plumbing is downstairs in three baths. Slab on Grade foundation. Two hot water heaters are upstairs in attic. No problem getting water. Regarding wasted line I have thought about going through one of the existing bathrooms by dropping the 3" line down the wall and tying into existing toilet waste line. I will have to cut up the concrete floor, patch together the pipes, etc. Sounds very messy. Also,I have thought about dropping a 3" line inside an exterior wall closest to where the main drain exists the house on it's way to the street. This will require cutting the side of the foundation to get pipe to the ground and patch into the main drain. Not sure about cutting the footing on a slab. I have seen where this technique is used and pipe penetrates exterior wall just above the slab and goes down into the ground. Not very pretty. My main drains exits at the front of the house. Any other thoughts would be welcome.
Thanks. Dave Seebeck
Anything Goes With A Drain
yes you can camoflage a drain pipe pretty easily
even in the front yard with a little immigantion...
what you got in mind I have seen done before,
just going down an outside closet and then instead of tearing up
the concrete floor, jsut going outside and digging down out in the ground
low m close to the slab....
I have seen poeple tie into the cleanout in the front yard too
and it didnt look too bad, if you got one, if you dont, then make one..
pine trees or other shrubs work pretty well
painting the pipe to match the house works too.
That didnt make sense-Cutting Concrete
Sorry I am a little slow in the AM. Anyway, what I meant to say, does anyone have experience notching the side of a concrete slab to allow for the stub out of the 3" sewer line below brick line. If I run into rebar can I simply cut through?
My city follows the 2003 international plumbing code. Does anyone know if this code allows for me to exit the building with the sewer line and tie in to the main line close to the house but on the outside versus inside?
Thanks. Sorry for the confusion.
