Requires a lot of flow to trigger
The paddle arm was too long for 3/4" pipe - it bottomed out inside the tee. Also, even on the lightest spring setting, I couldn't get the switch to trip even with 7 GPM flowing. I'm going to try to salvage some parts, but I may have to make some major modifications to get it to work.
