Noxious smell coming from bathroom
I have a question concerning a noxious smell coming from our bathroom. The smell is coming from the closet that holds the water pump, instant gas water heater and water tank. For the last couple of weeks the smell has progessivly gotten worse. It smells like a mixure of gas and sewage. We live in a very rural location and have a septic and get our water from a drilled well. At this point I do not know the size of the septic but I do know it was put in 4 years ago, has not been pumped or had any maintenance done to it, and at the time was put in for a one bedroom house. Only my wife and I live in the home. I am wondering if it is a problem with the septic? My wife gets frequent headaches when she comes home from work and is quick to notice the smell. I however work out of the home and only smell it when I go into or pass by the bathroom. Due to living in Maine we are unable to air out the bathroom very often in the winter due to the outside temperatures. I am wondering if it might also have something to do with the "stink pipe" venting out of the roof from the bathroom being clogged. Any thoughts or advice would be grealy appreciated.
Thanks,
Todd
