I bathroom addition to the basement quickly progressed to replacing all the sewer lines. I have used 4" PVC and a fernco where I tied in to the 4" CI right before it goes through the footer and out to the street.

Someone gave me the advice that I should use concrete and in case the fernco before pouring the floor to protect the rubber. Do I need to do this? Will this effect the life of the fernco?

Thanks

Hi Scott,

It isn't necessary to protect a neoprene gasket. The only thing I know that will destroy neoprene is oil,grease or any petroleum product. Good luck. Tom
