I've been living in an apt for about 6 months and about a month after moving in, the toilet will overflow occasionally, and has been getting progressively worse as the weather has turned cold. I've poured everything available to me from Drano to enzymes to alleviate the problem and plunging it every time, but it only lessens the frequency of an overflow for maybe a day. This is an older apt, and I took a look inside the tank the other day, and it was black where the water is. I'm getting very frustrated because my landlord isn't doing anything about it and it is overflowing everyday. Please help, I'm sick of washing towels to clean up the mess!
