I would like to get some thoughts and resolution options to the problems with the old Toro Pro Flo Valves (#284). I have been seeing more and more of them failing to the weeping problem. especially at blow out stages. The diaphragm will not close down completely. I have just talked the cutomers to replacing the entire valve ( of course I am not replacing them with TOROS) . But some customers are freaking out when I tell them the cost to rebuilt an entrie manifold at times. Are any of you using the repair kits? Are they worth it? I also heard from another group that you can use the Rainbird DV100 repair kit??
