The pipes under my kitchen and bathroom occasionally leak. The wood is damaged. Tired of having my towels and toilette paper soaked. Thank you for your response to fixing the sink pipes. Plumbing problem, that I see is directly under the sink. The pipes are of different materials. The stem of the sink looks like copper since it has blueish tarnish on it. The curvy parts are PVC with wings to help screw it in. In the bathroom, I took the pieces apart, cleaned them, put a white plumbers tape around the screw-on grooves and hand tightened the ensemble. Should I have done more? I want to fix it not just “Mickey” it.
When you are mating two different types of pipe you cannot reuse the gaskets or washers… you need new ones. There is a “goop” that you can put on threads to really seal them from leaking… also seals them from redoing the repair. I suggest taking a few pictures and the leaking ends of the pipe to your local hardware/building supply store and asking for their help/suggestions. The original “plumber” may have use poor or improper materials or left in cut/worn gaskets. If this answer is acceptable please remember to return and mark it.
