 No hub rigid coupling can it be in concrete?
Author: sum (FL)

I used a no hub coupling "PROFLEX" (the one with a rubberized sleeve and a rigid metal sleeve outside of that tightened by two screens). The coupling is about two inches below grade and I will be filling back with some concrete.

Is it ok for part of that coupling to be embedded in concrete or I need to tape/wrap it with some plastic sleeves?

Thanks,

You could wrap it but as long as it is oil resistant type it should be good for fifty years or so.Good Luck.

Haven't seen one wrapped, or done it myself, so far.

"YES", what? Two diametrically opposed questions.

Sadly enough ,Sum .Sounds like you should have planned where the no hub would end up and not left it as a question.Good Luck.

I did. I cut the CI pipe 6" above grade. I told my plumber I want to have my kitchen sink stub out 13" above the floor. I also told him I like to have the cleanout in the stack above the tee, and use 2" drain all the way to the tee.

He ignored everything I said and put the cleanout below the tee, and used 1-1/2" drain pipe, and ended up about with the stub out 16.5" above the floor.

I then told him this is too high, that the easiest thing to do is to swap the position of the clean out and the tee and all will be solved.

He ignored me again and instead of swapping the fittings, he cut the CI pipe by an additional 4.5", resulting in the CI pipe 1.5" above grade. he did that and found out later. I thanked him and paid him.

I then removed everything he did and did it myself. Did not take me long at all. I only ask him to do it because I had a contract with him and that was part of it. What a hassle.

That is why the CI pipe is 1.5" above grade and the no hub coupling will be partly below grade.

I planned, I just cannot control what others do. Oh well.

Now, I will not tell you about the AC company I hired to replace my air handler after I specifically told them to not cut any lumber in my attic they cut two web members of my truss. I want to choke someone.

You seem to have the worst luck. I'd consider a film crew to document this project. Maybe you could get a reality series deal out of it.

I also wouldn't lose any sleep over concrete around a no hub coupling.

You could wrap some 10 mill tape around it quicker than you can read this thread, but it's probably ok without it.

if the top of the cut pipe is 1.5" above grade then the no-hub should be .5" above grade so why the worry?
