In response to Re: 3" or 4" toilet dwv - is one better than the other.
: : We're renovating our bathroom and installing a new half bath. In the new half bath we plan to use the 3 gallon toilet from our old bathroom. My question is it better to install a new 4" branch drain or should we go with a 3 inch? Is there any benefit to installing a 4 inch?
No benifits to the 4". Use the the 3", it will work fine. Don't forget your back vent.
