First I had a problem with a stopped up toilet on the second floor. Called a plumber–he didn’t find it. Now the same toilet runs constantly and takes forever to fill. Then the same toilet overflowed. Then I noticed water on the ceiling in the kitchen and I’m hoping it’s related to the toilet problem and not something else. On top of all that, I noticed that the powder room toilet (on the first floor) would not flush today. I’m going crazy between the running, overflowing, etc. PLEASE PLEASE help me. I am prepared to buy a new toilet for the second floor, but what about the first floor?
