How do you seal plastic overflow drain hole on bathroom sink?
Had an experienced plumber (30 years experience) install a new replacement Briggs Homer 3002 lavatory in my bathroom on November 11, 2011. A new supply line, P-Trap, and pop-up drain stopper was also installed at the same time. I have had plumbers come out three times to fix a small leak at the bottom of the sink/plastic overflow drain opening without success. The pop-up assembly has been replaced and reinstalled with new putty several times. This has been a sink from hell and is giving me nightmares. Photos of the leak and plastic overflow are attached.
The Briggs CS rep asked if silicone sealant was used on the drain pipe that goes into the plastic overflow opening on the bottom of the sink, and if the plumbers had installed sinks with plastic overflows on the bottom of the sink. I know that no silicone was used since I watch them try to fix the leak. Don't know if they have installed plastic overflow type sinks in the past . I have used these plumbers several time in the past and they are competent. Sink installation and other plumbing work is what they do every day.
How should the drain pipe at the bottom of a sink/plastic overflow outlet be sealed?
