Mold in sink drain!!!!!
Six weeks ago, there was a black, powdery mold growing out of a bathroom sink drain. There are double sinks in this vanity. I don't believe I saw the issue in the other.
I closed the drain and made a 50% mixture of bleach and water. It slowly leaked through the "plug". I wiped the residual mold around the drain plug away.
Tonight it is back.
Any suggestions on how to treat?
Do we need to put a new pea trap and pipes above?
The sewer pipe that served this bathroom was broken this spring and since was repaired. Is it related?
It gives me the heebie jeebies...like something from an Alien movie! Please help!
