The Root Cause: Troubleshooting Common Flush Valve Problems
Commercial flush valves—or flushometers—are precision instruments. When they fail, it’s often due to one of these common technical issues. Our experts know how to fix them all:
| Symptom | Our Diagnosis & Solution |
| Poor Flush | We’ll check the water volume and pressure. Often, this is caused by a low flow issue, a faulty water-saving kit, or the wrong part installed for the fixture. |
| Flush Valve Runs Constantly | For Diaphragm type valves, this usually points to a clogged bypass orifice or a faulty solenoid/diaphragm assembly. For Piston valves, it’s often debris or a worn relief valve seat. |
| Flush Lasts Too Long | This suggests a clogged bypass orifice or a pressure issue that isn’t forcing the relief valve to seat properly. We’ll clean and replace the diaphragm assembly if necessary. |
| Short Flush / Shuts Off Immediately | This often indicates a worn diaphragm assembly, a damaged handle, or a relief valve that needs to be replaced with one calibrated for the correct flush volume. |
| Splashing or Leaking Water | Leaks can occur at the handle, cover, tailpiece, or vacuum breaker. Splashing is often caused by a control stop that’s opened too wide or the wrong diaphragm assembly installed. |
Don’t let these complexities slow you down. While this technical information is helpful, trying a DIY fix can often lead to further damage. Our experienced plumbers quickly identify and fix the exact problem to local standards, guaranteed.
