Question re pipe covering under kitchen sink
There is a series of pipes running along the back of the wall underneath my kitchen sink. They appear to have been covered with some kind of material that is now disintegrating (it peels off like layers of cardboard and smells mildewy especially now that the weather is warmer).
I checked and there is no leaking taking place, and the material doesn't feel wet to the touch (dry but just sort of spongey). I have odor absorbing crystals for the mildew smell but I realize that doesn't solve the problem.
Should I get a plumber in? Other than this issue the actual pipes themselves are perfectly fine.
