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.
If seams of fissured rocks, such as soft clay, or shale exist below the foundation, the side thrust of the water pressure may shear the whole dam and cause its failure. In such failure the top of the dam gets cracked and subsides, the lower slopes moves outward and forms large mud waves near the dam heel.
