I am a widow raising a daughter, and I am getting used to some of the easier aspects of home repair, but something happened this a.m. that is just weird. Any help would be most appreciated. I cannot afford to call a plumber.We have two bathrooms in our place. This morning I went to the back one, used the toilet and took a shower with no problems. A half hour or so later, my daughter went to do the same and came to tell me that there was water around the back toilet. Figuring it needed to be plunged I went back and checked it out. The water level in the bowl was normal and it flushed fine.
Then I went to the front bathroom to grab a few towels we keep for dirty jobs, and there was water all over the floor and heading for the hall. This toilet is only for company, and hasn't been used in several days. It also flushed fine.We put towels on the floor around the back toilet and I went to work mopping up the front bathroom. Then we checked all over the house: showers, sinks, the washing machine -- it's just the two toilets.
Next I decided to call the city water department to see if they had been flushing the lines or something and it was pushing water up through the system (but just the toilets? I don't know anything about how the water system works).The city sent out a crew very quickly. They opened something up in the front yard (had to break it open because they said it hadn't been opened so long it was stuck). They took a look inside and said everything was fine, nothing backing up, so it had to be the toilets (both toilets, simultaneously?).Before they left, they asked us to go flush both toilets again. When we did water came out of both toilets, not out of the tank or bowl, but out of the base at the floor.
Does anyone know what is going on? Have the seals on both toilets broken at the same time? I don't know what to try next, but we need to have one working toilet soon.
