Troubleshooting PEB Valve | Problem: Valve Won’t Shut Off
| Cause | Solution |
| 1. Flow control full open | 1. Prevent the diaphragm from opening further than necessary by trimming the flow control to one-half turn above the position where proper sprinkler distance is achieved. |
| 2. More than one valve open at a time draws down inlet pressure and valve has trouble closing. | 2. Utilize station delay feature of controller, or change station timing or sequence to prevent two high flow valves from being on at the same time. |
| 3. Diaphragm/valve seat fouled or damaged | 3. Flush valve with manual bleed. Remove diaphragm and inspect diaphragm and valve seat for damage or debris. Clean or replace diaphragm and reassemble valve. |
| 4. Diaphragm damaged or misaligned | 4. Turn off water and remove bonnet. Check alignment of diaphragm with valve body, inspect diaphragm for nicks or damage. Realign or replace diaphragm as necessary. |
