A real mess

**pick** · 07-20-2009, 10:00 PM

So I was rerouting a 2" pvc vent and broke it at a 45 degree fitting at the slab level. Was trying to union a 4' new section between two cut sections and of course the 2" does not bend enough to get one end into the union. Question, how does one union a section between two older ones? On the net I saw a telescoping coupling. Would this do the trick and within code? I'm going to dig out the 2" drain stub to attach a new 45 but will still face inserting a new section above the slab. Any assistance is greatly appreciated.

They make a slip or repair coupling. It does not have the stops But the trick is to properly align the coupling onto both pipes when sliding it into place, and work fast before the glue bonds the coupling where you do not want it bonded.

You use a "No-Hub" type coupling to join the two ends.

Thanks for the replies. I did see that coupling at the orange box and will pick one up and give it a try. Now where's the jack hammer!

Do not use the all rubber ones...it must have a stainless band that goes all the way around the rubber...making the whole assembly ridged...all the HDs out here do not carry the banded couplings...only Low*s carry them...

Some areas will require you to use a PVC to no-hub adapter fitting if you plan on using a rubber no-hub coupling.

Is this the coupling you are refering to:

Thanks

Yes, although the picture is not for the one you need. The one shown is a reducing coupling and you need a straight one for your pipe size.

Thanks HJ. The vent is a "wet" vent and will be sealed inside the wall. I have two airconditioning units in the attick that are plumbed to this vent stack for the condensation drip. So is this coupling "code" for such an installation?
Thanks again.
