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.

Side Channel Spillway. Side channel spillways are located just upstream and to the side of the dam. The water after flowing over a crest enters a side channel which is nearly parallel to the crest. This is then carried by a chute to the downstream side. Sometimes a tunnel may be used instead of a chute.
