Does anybody have any experience with the ECHO SHR-210 in the way of modifications? I'm thinking of getting one and will want to modify it for turfgrass applications with a 50 psi max pressure regulator/bypass and a new wand that will take TeeJet tips. Looks simple to do except for the pump outlet port. I'm not sure what the thread is. From the factory there is a T screwed into it that has an O ring and locknut. I would like to remove that and connect to the pump outlet with my own T for the adjustable pressure bypass back to the recirculation and the spray hose. Any ideas?
