So I finally found a set of your Richdel 204s (the other ones in the other thread were a mixture of weathermatics and older irrtriols) I have three of them, The solenoids were either bad or in one case the solenoid threads were bad so the solenoid would not stay IN the valve. So I replace all the solenoids with new irritrols, it works on 2 of the 3 valves. The other valve I cant get to open now at all, even when I take th solenoid all the way out of the valve...it wont open, but I have had it open before. Doesnt matter which irritrol solenoid I put on it or even if i try the old irritrol. I can't get guts or parts for the richdel... sooo If I open it and there ISNT some peice of something stuck in it, what are my options? I had this dang valve opened ealier (manually), and I thought it had something to do with the solenoid, but aparently not.
