Use of Fernco
 
We're having cement work down around our pool club. The mason inadvertantly damaged one of our PVC pipes (2" pipe). It is either a supply or return...not sure but it really doesn't matter.

Our operations guy wants to fix the broken PVC with new pipe and PVC couplers. There is NO play in the existing pipes and I don't think the pipe could be set fast enough (it would be glued). I think a better solution is a Fernco Coupler. The ops guys is not convinced that it will hold up under potential high pressure, and is also concerned about the longevity of the coupler.

I believe that Fernco's can be used in pressure scenarios, and that it will last at least 20 - 30 years.

Can somebody provide insight as to who is right?

Thanks!
Dave

You can not use fernco couplings for pressure applications.

Sorry for tell ing the bad news.

Just do an offset with 90's.

I agree with Ron... [and I have an in ground pool]

I would not use that type of fitting on a supply or return line. Especially if its going to be concealed later by dirt, concrete, etc.

They work fine for waste or vent where they are not pressurized, but I wouldnt try it in your application.
