  Replace with proper flushometer. Crown flushometers are not available with flush volume higher than 1.6 gpf/6.0 Lpf.

  D. Inadequate volume or pressure at supply.

  Increase water pressure or supply (flow) to valve. Consult factory for assistance.

• 4. Length of flush to long (long flushing) or fails to close off.

  A. Piston is not seating properly or bypass orifice is clogged because of foreign material, or bypass orifice is clogged by an invisible gelatinous film from "over-treated" water.

  Disassemble the working parts and wash thoroughly. NOTE: Size of the orifice in the bypass is of utmost importance fro the proper metering of water into the upper chamber of the valve. DO NOT enlarge or damage this orifice. Replace Piston if cleaning does not correct problem.

  B. Line pressure has dropped and is not sufficient to force Relief Valve to seat.

  Shut off all control stops until pressure has been restored, then open them again.

  C. CR-125-A main seat is fouled with debris or is worn.

  Clean or replace CR-125-A main seat.
