  C. Insufficient volume or pressure at supply

  If guages are not available to measure supply pressure or volume of water at the valve, completely remove the working parts and open the stop valve to allow water to pass through the empty valve. If the supply is adequate to siphon the fixture, the guide ring (#17) may be removed from the guide assembly to provide additional flow. Should this prove unsatisfactory, steps should be taken to increase the pressure and/or supply.

• 3. Flush valve shuts off to quickly

• 6. Water splashes out of fixture.

  A. Supply volume is more then is necessary.

  Adjust downward on control stop.

  B. Lime accumulation on vortex or spreader holes of fixture.

  Remove the lime build up.

• 7. Flush is not considered quiet.

  A. Control stop may not be adjusted for operation.

  Adjust the control stop for quiet operation keeping in mind the fixture evacuation requirements.

  B. Fixture may be contributing to noise.

  Check noise created by fixture by placing a cover over the bowl opening to separate valve noise from bowl noise. If it is determined the fixture is to noisy, consult with fixture manufacturer.

  C. Piping system may be source of noise.

  High pressure in the system can sometimes be controlled by the stop valve. Other sources of noise may be the absence of air chambers and shock arrestors, loose pipes, improper size pipes, etc. In these cases, the building engineer should be consulted.

• 8. Handle assembly leaking.

  A. Handle assembly is not tight.

  Tighten handle assembly.
