Drain noise,slow drain and bad smell from under house.
I am trying to find if we have one problem or many. When it is very wet weather we have slow drains. Some times when running the washer it causes water to back up into the bathtub. Water also comes out around the bottom of the toilet. There is a lot of glub-glub noises that come from the kitchen, bathroom sink and the toilet.Loud enough that our 2year old runs in to check the toilet for fish! There is a strong smell that starts in the bathroom closet were the back side of the central air vent is and can also be smelt in the bedrooms. It is not smelling outside around the scept tank. When the weather dries up we still have the noise and smell. It just isn't as bad. Do not know if it is to do with drain or the outside fill lines. Thanks so much and hope someone can help.
