Adjusting the Pressurstat Line Relief Pressure
Pressurstat line relief pressure is the line pressure after the pump stops.
1. All pumps are factory set to a line relief pressure of 23-28 psi (160-195 kPa).
2. Remove the protective cover (see Figure 18).
3. Adjust the relief pressure to the desired level. Turning the adjusting screw clockwise will increase the line relief
pressure. With the adjusting screw fully down the line relief pressure should be from 40 to 45 psi. With the
adjusting screw all the way up the pressure should be from 0 to 3 psi.
4. The line relief pressure can be verified in three locations:
a. The pressure can be observed from the control unit of the electronic line leak detector.
b. The pressure can be observed by attaching a gauge to the impact valve.
c. The pressure can be observed by attaching a gauge to the line test port.
5. After setting the desired line relief pressure replace the protective cap. DO NOT USE PIPE SEALANT.
Lubricate the o-ring with petroleum jelly. Tighten to just snug after the protective cover has fully bottomed out.
