A) Wrong flush volume regulator installed in flex tube diaphragm kit; instal the correct regulator.
B) Control Stop not adjusted properly. Readjust control stop.
C) Wrong Sloan SOLIS® model installed; i.e., 3.0 GPF model installed on a 1.0 or 1.5 gal Urinal fixture. Replace with proper Sloan SOLIS® model.
D) Dirt in diaphragm bypass. Clean under running water or replace flex tube diaphragm.
DO NOT use abrasive or chemical cleaners to clean flushometers as they may dull the luster and attack the chrome or special decorative finishes. Use ONLY soap and water, then wipe dry with clean cloth or towel.
While cleaning the bathroom tile, the flushometer should be protected from any splattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating.
