Flush cycle too short
- Adjust timing valve (sometimes referred to as Bleed-Off Plug in the manuals) – Tighten by a quarter turn and check flush cycle after each turn until the cycle is between 4-6 seconds
- Timing Valve hole is too large
- Air lines could be leaking
- Check for air line leaks at all connections
- You may have water collected in your air cylinder.
- Fix #1 (more time consuming): Pull the toilet off of the floor, remove the air cylinder, disassemble, empty it of water and re-lubricate it before reinstalling
- Fix #2 (less time consuming): Shut water off to your toilet. Shut off your air to the toilet. Empty air compressor(s) of any water–even if you have automatic drip leg(s) and/or air dryer(s). Turn air back on — LEAVE WATER OFF — Flush toilet 10-12 times with only air supplied. This will help purge all of the pneumatic valves of moisture.
