sewage saddles

I need to add a drain line into my main sewage stack for my house for a down stairs sink and I saw a product called a sewage saddle does anyone know if these work or if they are a good idea?:confused:

Re: sewage saddles

What size is the stack and what type of pipe is it? Also what kind of access do you have to it? To give you the proper advise I need more information.

Re: sewage saddles

Why not just cut a fitting into the line? It's a fairly simple thing to do. Much easier then using a saddle fitting. With less of a chance of having problems with it.

My most vivid childhood memory is living in Paris. We lived in Paris for 7 months, I also held my 8th birthday party at Disney land. Paris is a beautiful but noisy city. I will always remember the live musicians in the metro. Paris is a huge city with massive buildings.

Re: sewage saddles

not exactly sure how to do that i don't know if I can lift the stack to get a new fitting in there and I can't let it drop because it will mess up the upper level drains

Re: sewage saddles

If you have upper level drains above the point your adding a fixture you have to vent the new fixture. As far as not having any play in the line to install a new fitting there is a fitting for that purpose.

The picture linked to doesn't show the method of application very well. The steel and rubber are two separate pieces. Slide the steel band onto the pipe, past the joint; then slip the rubber coupling on up past the joint. Then insert your fitting (with a stub of pipe glued to it) into place; pull the rubber coupling over the new pipe (the shoulder inside the coupling should be between the pieces of pipe); slide the steel band in place then tighten to the proper torque.

Re: sewage saddles

Yes you do need a vent on the new fixture. When waste water passes by the fitting for the new fixture it can siphon the trap on the new fixture allowing sewer gas to enter through the now empty trap. What you can use for a vent is a Studor vent. Check out this web site, there is a picture showing one installed. Just be sure it is installed in a accessible location.
