Trouble shooting guide:
Before calling about a Backflow, refer to this simple procedure to identify the cause of discharge from the relief valve port.
After observing water discharge from relief valve port:
1. Close #2 shut off valve. If discharge stops, the problem is a fouled second check.
2. If discharge continues, open #4 testcock. If discharge stops or is reduced, the problem is a fouled first check.
3. If discharge continues, the problem is most likely in the relief valve.
SOLUTION: Disassemble and clean affected components and remove debris from the backflow preventer.
If this procedure does not remedy the RP device from dumping, the problem may be system related.
