Need to tap into 3" drain pipe from washer. This tap will drain two vanity sinks. Should I use a T fitting or a Saddle? Im not sure I can squeeze the T fitting between the lines if I cut it.?. The line is about 15' long so I may have a little play between the two, but I'm not sure there is enough for a T.?. What is your experience with Saddles? I thought about using alot of glue for the T, to keep it slick, and trying to do both ends at the same time. Slide one end all the way in, enough to get the other end into the T, then sliding it back over centering it between the two cuts. I was working with some 3/4" pvc yesterday for my hvac condensing line and I noticed that if I got a little sloppy with the glue, it was pretty easy to slide around for about 10 seconds.
