Out of the blue, my main bathroom that guests primarily use starting having an earthy smell coming from the sink drain. Its on the main floor, and there are no floors above it (in other words, not another sink above it). I examined the plumbing under the sink, and everything seems to be in working order, no leaks, trap is in good shape, etc.What should I do here?
suggest that the trap is siphoning dry ,there should normally be no smell if the trap stays full of liquid at all times, unless you have a leak in the vent line.
Pour some bleach and hot water down the drain.
is the water draining good,can you see a swirl ? cover any overflow hole in the sink,fill it up and give it a plunge,you might find that you have some residue in the waste pipe then add disenfectant.is the sink wastepipe connected to anything else,has it got a decent run on the wastepipe? if not it could be stagnant water,try a few plunges 1st and then start looking at the waste pipe.
In the bathroom, what you has happened that is causing the odor is that mainly hair that has gone down the drain has BUILT up and is clogging the drain at the PVC bend under your sink. Drano and other liquids don't really solve your problem in terms of how long it might last before recurrence, rather the Best Practical Solution is to get a Long Handle Pliers or Pipe Wrench that will twist off the PVC Tube (of course you need a flat pan underneath to catch some water) and once you have it off, you clean it out and dump the trash afterwards. Then reassembling it, you will need either Teflon tape or another temporarily (don't use permanent PVC glue bec it is meant to be taken of) substance <= visit Home Depot or Lowes Plumbing) and before you go, make sure you test & check that your long handled pliers or pipe wrench can open wide enough. Then after you reassemble everything, you simply turn on the water and test for leaks, and if none, you should be Good to Go! Hope the Above Info Helps and Best of Luck!
