Check the pump literature. I mave a PAR pump that has a pressure adjusting screw on the pressure switch.

Hi Hans
The pressure relief valves should be exercised regulary to prevent build up on valve, I'm sure most people do not do this. Try exercising valve for a few seconds may clear build up or residue and solve your preblem. Best of luck.

I checked the relief valve and cleared it from salt depostits, now its working ok.
Thanks
