Do the new irritrol parts first those?
All the current Irritrol Century Plus valve parts match up. The gray giaphragm seat ring was replaced along with the diaphragm, spring, and bonnet top end. Only thing left in the ground was the body.irrig8r said:Irritrol solenoids will fit 'em, but you have to take off the plunger retainer and be careful of the brass threads as you thread the solenoid into the bonnet... BTW, the solenoid in the pic was likely not the original. The original HRs were horseshoe shaped.
