Great, thanks!!

What I refer to as the 'main' is the shutoff that is outside the home, at the meter. Sorry if I did not use the correct terminology.

As for inside the home - there is only one shutoff, the branch...

My home is 80 years old, and unfortunately the previous owners did not install a single shutoff aside from the main at the meter. I'm going to install a shutoff at the branch that goes off to the...

Okay, simple question.

Terry,

Based off of the link you gave me, I fit into the 1' per branch category.

would you then recommend 1" to supply the main branch, then each area (e.g. kitchens, bathrooms, laundry area)...

Steve,

I can't speak for your situation, but due to the help with other people on this forum, I was pointed in the direction of using a sanitary tee with a side inlet to be able to do both. ...

Same here - 80% of my house is knob and tube, and all on one single circuit. Home inspector missed it by a mile.

Which is why I'm in the process of a whole house rewire...

Well...I'm installing a new bathroom on the second floor and the house currently has 1/2" throughout - it's old and starting to get deposits in spots and causing problems with pressure.

Also, I...

The water line coming off of my main shutoff is 1/2" - am I able to increase the pipe to a larger size right after the main shutoff without losing much pressure?

Right - 2" is both code and is appropriate for everything that is being vented.

That's not my question - I am wondering if a 3" stack will work just as well as a 4" would for my scenario.

I know that I don't need any 15A circuits, my question was more along the lines of which rooms need to be on their own circuits for outlets, and should the light fixtures be on their own circuit...

I recently purchased my 80 year old home and am beginning to remodel. During the process, I will be replacing most of the existing iron and old copper pipe with new copper supply pipe.

This toilet is installed highest on the soil stack

Nope, that's all. Thanks for the info

I've communicated with a master plumber on another forum, but wanted to check with you all on what he said.

I have a toilet that is 4' away from the main stack, and a shower that is 2' away. Is...

I recently purchased my home that was built in 1930 and found that 80% of the house is on one single 20A knob and tub circuit.

YIKES!

So while I'm working on my bathroom and have a portion of...

The stack is serving two bathrooms, and that's all. The connection would be made roughly 4' up the stack using a 4" TY with a 2" inlet. The connection is in the basement.

The 4" TY will service...

Sorry, I was not being clear. The stack is a 4" ABS. The TY would be 4", with a 2" inlet.

The stack will serve two bathrooms, and that's all. A total of five fixtures - one tub, two toilets,...

Quick question for everyone -

Am I able to stack vent a toilet and shower into a 4" ABS stack using a TY with a 2" inlet? Both the tub and the toilet are within 6' of the stack. Or should I...
