I want to start by thanking everyone for their help. It has all been very useful and our remodel is going nicely.
Here are todays questions:
I need to put in a toilet that would require a 21' run to the main stack. Is this too long, or as long as I make sure the slope is 1/4"/ ft, I'll be alright?
I have enough room to drop the required 5.25" with only one elbow to reach the main stack. First part of the run is 12', elbow, 9'.
how does this sound?
There are 2 other toilets that join together and then attach to the main stack. These toilets have a vent pipe that goes out the roof. The toilet I will add will connect directly to the stack and not join the run connected to the other toilets.
Does this new toilet need a vent pipe of it's own?
Once again, thanks in advance for the help.
