    More specifically, researchers at the University of Virginia found that bacteria can happily colonize a sink’s P-trap and then sneak back up the pipe and into the drain by forming a protective, creeping film, called a biofilm, on the plumbing.

    Caroline, I had no idea that the p-trap was designed to hold water and keep the sewer gas from entering the bathroom. I am now more appreciative of this design. It was also interesting to see that latex paint contributed to your old p-trap’s failure. I’ve never looked under my sinks before. You’ve got me thinking that I should look into replacing them. I suppose it will be very important to get good quality plumbing supplies from a trusted seller.
