PVC Slip Fittings?

I know they make copper slip fittings for the situation of putting a piece of copper in between 2 fixed pieces of copper (I've used these slip fittings when repairing copper pipes in baseboard heat sections that were busted from freezing).

Do they make PVC slip fittings for the same situation with drain lines?
How do you do this with drain lines? ferncos?

Ask for a "DWV repair coupling".

They do make repair couplers that have rubber gaskets that work on both drain and pressurized systems. Problem you would have with regular slip fittings is the solvent will set up too quickly to slide the fitting onto the second piece.

Yes PVC slip couplings are available at any plumbing supply house....I use them anytime I need to without any problem.

I try to keep a good selection of these compression coupling available at all times. They work great. I keep PVC and CPVC and galvanized. They also make brass fittings for the copper pipe/tubing that has the brass ferrules which act like the rubber parts of the others mentioned. I've seen alot of apartment maintenance guys use the brass type with copper to hookup water heaters and did a good job.

Use a banded coupling to connect PVC to PVC. It is faster, easier, less messy, and can come apart if necessary.

Ferncos are not allowed unless it is under ground.

Banded couplings and compression fittings?

Hello all,
Thanks for the advice
1.What is a compression fitting and how do they work in this application?
2. What is a banded coupling and how does it work in this application?
3. Riohyde, When using a pvc slip fitting you must have to work super-fast to keep the PVC from bonding.

Fast, but not "superfast". I slip the coupling onto one of the pipes, mark on the other pipe where I need the edge of the coupling so both pipes are equally in the coupling, I never use cleaner/primer on a slip coupling...sometimes will sand it with some sandcloth if the pipe/coupling is dirty, use a good amount of cement on the pipes, slip the coupling on rotating it as I do, then slap a little more cement on around the edges. Seems like alot when I type it out, but its not bad at all. You might be better off though using a banded coupling like Cass suggested. I use the slip couplings because I dont routinely do repair work. Inspectors around here (i.e. Warren County, Middletown, Hamilton...Cass probably knows all about these places) dont really like to see a banded coupling on new work. Again, like Cass said, you can take a banded coupling apart if need be making them more forgiving than a slip coupling that you get one shot at.

Good luck

Yes, while they are code, inspectors don't like to see them on new work. I do mostly repair work and they are great for that.

banded couplings and ferncos

Hello,

Cass, or anyone else out there in plumbing land,

Are banded couplings the same as ferncos?
If not what is a banded coupling?

TIA,
Molo

Banded coupling - no-hub. these have a band to keep the pipes aligned and are okay to use above ground.

The fernco (a brand name) is basically a rubber sleeve with hose clamps at either end - this is okay for underground use since backfilling the hole properly is assumed to keep the ends aligned.
