Rebuild kit just showed up on the Big Brown Truck... Slapped it together and installed. I'm generating chlorine again, the bubbles are gone (only ran for a few minutes, will confirm when the run cycle kicks in tomorrow) and the pump appears to be undamaged.

I still think I need to mount the cell vertical so if we can get the pics up, I'll look for opinions on adding the number of 90* angles it would take to do so... I'm thinking 4.
