We were getting that on and off for about a month and then 2 days ago the lines backed up and nasty crappola was in the shower. Oh boy was it a mess. Had to call the plumber we had a clog between the house and the sewer. Our master bath was the lowest point. Keep those drains free and clear. Good luck
Are you on well water? The well itself needs cleaning. Call a plumber or check on line how to do that. My bro-in-law had this problem for years and when replacing the pump found that the pump and line down into the well was full of moldy, stinky stuff. They poured a bit of bleach into the well and now, after years, there is no smell. But check first as I'm not sure how it all went down! I just know now I can brush my teeth without gagging! Usually the hot water was the worst! Good luck!
Don't know what is causing it, maybe a slight clog somewhere between the kitchen and bathroom? Have you tried pouring some baking soda and vinegar down the drain? This usually works in my kitchen sink.
Chinese DrywallL: Just last night I heard a warning on the Radio (KOMO news radio) that there's a warning out about Chinese Sheetrock. If your bathroom has been renovated in the last 4 years with new sheetrock or you live in a new home built within the past 4 yeas then the drywall may be your problem. This Chinese sheetrock is manufactured using fly ash which is a waste product of coal burnt in power plants, it poses a health hazard to children & those with environmental sensitivities. It can turn air conditioner vents black, tarnish silver & other mentals & cause rusting & It also reacts with copper so it can also turn electric outlets black. This Drywall has a distinct Gray color & it emits a "rotten egg" odor. For more info, you can Google "Chinese Sheetrock" or "Chinese Drywall".
Here's what they say:
"After new home buyers in Fort Myers Florida complained about the sulfur odors, the builder had the Chinese drywall tested and determined that it was the problem. The builder replaced the drywall in one house and used ozone, fogging and barrier paint in the other"
"It is the drywall, and from what I gather it is causing a problem with it reacting with copper and, specifically, air conditioning units"
"Since moving into their new home less than 3 years ago, a Louisiana family has suffered from consistent headaches, itchy eyes, a dry cough and other symptoms. They suspect that the Chinese made sheet rock in their home is to blame. The sheet rock is manufactured using fly ash which is a waste product of coal burnt in power plants. It emits hydrogen sulfide gas and has the faint odor of rotting eggs. This gas has also turned much of the family's jewelry black and the cooling coil in the air conditioning system has been replaced due to rapid corrosion."
PS. If you don't have this drywall, then you have sulfur somewhere else in your bathroom. It also can get into your well water (if you're on a well you should get your water checked out).
