Thanks so much for both replies...I'm going to look into them and see if either might work. Appreciate the help, John
I'm having a problem with the main solenoid valve . When the valve turns on there is considerable chattering of the valve and the pressure is reduced to the point that the heads don't rise. If I close the ball valve upstream, and open it slowly, the problem corrects itself. Where can I find replacement parts. The marking on the valve is HARDIE 3591126. Any help would be greatly appreciated.
