install T-Fitting
Author: roxald (Non-US) Good day all, I am trying to install a T-fitting in my 3" horizontal line to connect a 1 1/2" drain pipe from my wet bar. Both ends of the 3" are fixed in concrete and I have about 4 feet of the 3" exposed to tie in. After I make the 1st cut to separate the 3" pipe, how to I spread the ends far enough apart to install the T-fitting? Rox

You have to use "repair" couplings, there are many different kinds, and drop your connection into the gap and then slide the couplings over the joint.

Author: roxald (Non-US) Thanks Fellas, that was my next option. The ones I've seen are a soft rubber shaped like an normal end to end fitting with a wide metal hose clamp across the entire width. I believe it is called a no-hub coupler? Appreciate the quick response! Cheers, Rox Edited 1 times.

Author: steve (CA) Even when it's not a "transition" connection? Why use a coupling with 2 different IDs, when the pipes ODs are the exact same?
