Problem: Volume of water is insufficient to adequately siphon fixture.
Cause: Control stop is not open wide enough.
Solution: Adjust control stop for desired delivery of water volume.
Cause: Adjust control stop for desired delivery of water volume.
Solution: Replace diaphragm assembly.
Cause: Low consumption diaphragm assembly is installed on water saver/conventional fixture or urinal diaphragm assembly is installed on closet fixture.
Solution: Determine the required flush volume (see label on valve or markings on fixture). Replace diaphragm assembly or relief valve for appropriate flush volume of fixture.
Cause: Inadequate water volume or pressure is available from supply.
Solution: Increase flow rate or pressure to the valve. If gauges are not available to measure supply pressure/volume, remove Relief Valve from Diaphragm Assembly and open the Control Stop.
If the fixture siphons: Additional water volume is required. Install higher flushing volume Relief valve or diaphragm assembly or cut flow ring from guide.
If the fixture DOES NOT siphon (or a low consumption flush is required): Additional steps must be taken to increase the water pressure and/or volume at the water supply.
