RP Backflow Trouble Shooting Guide

THREE STEP 
RP TROUBLE SHOOTING GUIDE

with Relief Valve dripping or flowing

 

 

1st STEP    Close second Shut-Off Valve. If discharge stops, fouling of second check most likely with backpressure in the system. 

2nd STEP   If discharge continues, fully open #4 test cock. If discharge stops, or slows, most likely problem is with the first check. 

3rd STEP    If discharge continues, or gets worse while #4 test cock is flowing, most likely it is the relief valve. 


IF RP IS SPITTING, IT IS MOST LIKELY DOING ITS JOB!

Address the cause of line spikes, either supply or down stream.
