Title: Champion Irrigation Actuator Rebuild Kit
Review: This is a great product that can be used to renew a sluggish irrigation sprinkler valve actuator. At a low cost, a lot of money can be saved. I bought eight and just finished rebuilding one valve actuator. It works beautifully. The one item of concern is that the new diaphragm is simply a flat piece of rubbery material, instead of having a circular bellow for expansion, as the old one did. This means that the diaphragm may want to stretch as the valve opens. How would this affect the life of the diaphragm? I don't know yet. The only other negative feature is that the kit does not include a bleeder valve screw, an item that commonly gets messed up. Just the O-ring for the bleeder is included.
Is the review positive or negative?
