I tried to fix 2 small holes in my 4" pvc drain pipe by cutting out a section of pipe and installing a coupler from HomeDepot. I got the coupler onto the bottom section of the vertical drain pipe, but by the time I wrestled the top part into position, the coupler was fixed - and I mean fixed - in place on the bottom.
I now have a stuck coupler.
Can I now cut the coupler off and get a longer one and retry this process? I'm wondering how long a coupler can be, or if there is maybe some simpler way to get this done. The gap in the drain pipe is now about an inch and a half. When I saw off the coupler that I idiotically stuck on, it will be more like 3 inches. Is there anything you can suggest?
Thanks.

What kind of a coupler did you use, and when you cut out the holes did it leave a gap between the two ends.

My guess is that your best way to repair this is to buy a fernco adapter and use it to join the two pipes together. It is a neopreen adapter that will slip down over the bottom pipe and slip back up on the upper pipe. This adapter will be about five inches long and have stainless clamps on it.

Thanks Lemetellu. I used a pvc coupler that's 3 1/4 inches long. The gap between the upper and lower drain pipe is about 2 inches, which was necessary to fit the coupler in the gap.
Will the fernco adaptor you suggest work with a gap of 2 - 3 inches? I'll track one down tomorrow if I can.
Thanks again for the quick response. Much appreciated. Happy New Year.

Yes the adapter should work for you very well.

Hi Blondax...

Letmetellu has you on the right track.

However, if you have absolutely no movement in the pipes you may need to purchase 2 fernco couplings (see image), or at a minimum, a new PVC coupling and a fernco coupling to join the pipes back together.

I would suggest that you cut the pipe so you have about a 6 inch gap, if possible, and then slide the fernco coupling up and over the pipe so it doesn't intefere with work area. Then you can either measure the piece and prime/cement it to the new PVC coupling and then prime/cement the coupling onto the pipe and kind of SNAP it into place and then pull the fernco coupling down over the pipes to join them. Or, you could slide 2 ferncos over the pipe ends so they are out of the way and then cut a piece that fits in between the pipe nicely and then simply slide both fernco couplings into place and tighten them up.

Both scenarios work well.. ;)

Back to you..
