For the past few months our toilet bubbles. It started when we would use the washer now it happens whenever any water is running. Our landlord came out during July and supposedly fixed the problem. He thought the house had a septic tank but realized it didn't. We are connected to the city sewer. Whenever we have any water running in the house whether it is the kitchen sink, bathroom sink, or tub, or washer the toilet bubbles (it has been doing this since Sunday 10/1/06 non stop before then it would do it periodically) and the toilet has not completely flushed since Sunday. When we flush, the toilet bowl begins to flush but then the bowl fills up to the top of the lid with water, and then it slowly drains but the waste stays in the bowl. I believe our landlord worked on the plumbing himself before we moved in the house in June. I believe the house was built in the 50s. I don't believe there has ever been a plumber to check on it. Reading other post most people say their toilet bubbles when another toilet is flushed but we live in a single family home with one toilet. What could be the problem and how can it be fixed? Also, our ice machine in the fridge is no longer making ice. I believe it hasn't been working since about Sunday as well. Could this be connected to the toilet problem? Thanks.
