Tapping into 3" drain pipe?

[Bogucki]

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.

Don't use either a tee or a saddle fitting. Use a combination wye and 1/8th bend, and two banded repair couplings.

Phish, what do you have against Saddle wye's? Out here that is what most all the cities and district require for lateral tie ins. I am just curious on why you don't like them.

SAddle....... Wye?? never saw one. I assumed the op was talking about a T saddle.

They do make saddle Y's but I wouldn't use them inside a home. In fact I wouldn't use them outside. If you don't have the play in the line to cut a Y in then do as phishfood suggested.

Ah, I see. I've already pulled a few of those out on some of the old plumbing lines. I thought they were kind of cheap. If I cant get enough bend, I'll use em. Thanks, you guys ain't half bad.

We are required to use them all the time. they make them for Clay, PVC and out of rubber. I don't like the rubber ones.

The way we do it is cut out whatever needs to be cut out of the pipe, attach the saddle whether it be epoxy or those dumb band clamps and then we pour a concrete lug around it. It is the standard in most areas here in SoCal. Obviously we like to cut out a section of pipe and put a wye in and do it like we all think it is supposed to be but I am just curious as to what everyone has against the saddle wye.

 

[johnjh2o]

Cris I haven't seen this happen, but there made out of rubber and there is a possibility that when snaking the line it could you could punch a hole in it. Keep in mind that is just my opinion. I just tend to be more cautious then I should be.

Makes sense. I don't like the rubber ones myself. We use clay on clay or SDR saddle wye out here and as they are not as smooth a transition as one would like they are proven to work (I think). We have thousands of them buried around here.

@ John20 I don't think you are being more cautious than you should be, it just sounds like are a professional. One that doesn't just fix the problem but always thinks about the next Guy after you and what might happen. Like with the rubber fitting and sewer snake. If someone used that fitting and did break it and never knew it, than that waste can contaminate ground water and depends were you live it can cause harm.

People really don't know what a plumber is, they think that we just install pipes and different systems. But we are doing one of the most important jobs there is. We are responsible for the health and safety to the public and don't anybody forget that. Without plumbers there would be more disease and famine in the world. So keep up the good work guys LOL

I had to replace one of those saddle wyes, I thought it was just another handyman solution. This is the first time ive ever heard of it. I work in Calgary btw

 

[Chris]

I curious was it a rubber wye or plastic or clay? What was wrong with it.

 

[Jayare]

It was abs on a copper stack. it looked like they used pl400 to seal all around it. It was leaking from the bottem.

 

[johnjh2o]

Sounds like it was a hack job to start with. They should have cut a copper Y into the line.

John

 

[Jayare]

Definatly a hack job. It was for a washing machine and it was tied in about 5 or 6 feet off the floor with the outlet for the washing machine duck taped into the wye lol

 

[phishfood]

Definitely not a hack job, then.

Using duct tape raises them to the professional level, for sure.

 

[Jayare]

Plus they used pl400, every plumber uses that to seal their joints, right? lol

 

[Mr_David]

pl400 I need to get some of that!1
