Ben, yeah, I gets it makes more sense just to unscrew all the the head and let them free flow through the zones. It should make for a heck of a waterfall out of the spa for that zone. The ones on the steps and spill out for the spa would be left intact so I don't have a geyser situation.

I'll get some pics of the whole shebang and send them to you.

I'm just trying to improve the situation as inexpensively as possible and hopefully make pool maintenance life easier. Yes, "inexpensive" and pool is kind of an oxymoron.
