If your tank ball or floater is not installed correctly, it could cause the flush valve to stay open. Unfortunately, this problem is not always easy to locate. There is rarely any sound associated with this type of toilet leak as it is an internal problem.
Caption Floodwaters pour over Texas dam. Water is seen flowing over the top of a dam at Padera Lake near Midlothian early Wednesday morning following days of heavy rain. Water is seen flowing over the top of a dam at Padera Lake near Midlothian early Wednesday morning following days of heavy rain.
It is not far--but I don't have the exact mileage. Yes, they do have a tour of the dam but I have never been on it. I have been to the dam numerous times though. If you have time, go North to Beatty, Nevada and visit Rhyolite (ghost town). If you start ealy enough, keep going through to Death Valley to see Scotty's Castle.
