I took the advice of someone on this forum and unscrewed the line at the bottom of the toilet and flushed out the line into a bucket. I probably flushed out about 20 gallons of water. With each fill of the bucket there were black rocks{iron sulfide?} although less as i flushed out more water.My original problem was the toilet wouldn't stop. I discovered these rocks were under the rubber seal in the Fluidmaster,preventing the toiulet from stopping.I have copper lines so i don't think it could be a corrosion problem. Could these rocks be coming through the city pipes? If so, how would they be able to keep it from coming through my lines?
