Had a new stool installed on Thursday about 11:00 a.m. I could hear throughout the day, every now and then, the sound of the tank filling a little bit. I figured that when my hubby got in from out of town, I would ask him to adjust the thing in the tank-I thought maybe the flapper was not set correctly...I do not know toilets! Friday morning about noon, I noticed the carpet was wet in the adjoining bedroom, I pulled the corner and it saturated. I called the plumber and said there was a leak somewhere. He came by and tightened one of the bolts. This stool has 3 on the bottom of the tank and one was loose. So, that is why the tank was filling a little every now and then. I showed him the wet carpeting and he said the tank could not have leak enough in 1 day to have the water run under the 6 foot vanity, or under the ceramic tile. I asked several times if there could be an issue with the wax ring. He assured me that is fine-he did not do the work one of his guys did. After he drove away my son and I saw water seeping up from under the laminate hardwood flooring-3 feet out from the bathroom threshold. So, we took that up and the pad was like a wet sponge. The plumber came back and he says we have to have leak somewhere else. He checked the water meter outside and it was not moving. Where do we go from here? That does seem like an extreme amount of water from a little toilet tank leak. Could the water be running under the tile? He suggested that we both shower this a.m....and then I filled the tub twice and set it to drain slow. The plumber suggested that we had a leak in the tub drain. We did not see any water since. Help, any ides?
