Want to add SWG....couple questions

[mneal]

The way the pool is plumbed thru the heater and jandy value and then off the slab I have no way of getting the cell between the valve and the ground, I have exactly 11 inches past the ball valve of all vertical pipe to where it goes underground. (unless it got really ugly and looped up or something, yuck). So I figured I could put the flow switch in the pool return and the cell before the jandy and ball valves. (I hope that makes sense). That would have same effect...all spa= no cell and not over chlorinate. Sounds like I for sure do not want the cell to run full power in just spa mode. So if I went with Total Control AP system it will not over chlorinate and adjust the Cl levels when it was just running the spa? (I knew it did the pH with acid but was not sure about Cl level, I guess that is the ORP thing). I really like the AP, plus it supports Sean a common supported/poster of my favorite pool site. Sean is it OK if I contact you off line to discuss cost options?

I have my aquarite plumbed right after the heater, so when in spa mode it still generates chlorine. I ran the system for four hours in spa mode, and then took a chlorine reading, which read only slightly darker than before(if my memory is and goodd)Unless you run your spa for many hours everyday, I dont think it would be a problem. If you are worried, you could just turn off the unit until your back in pool mode.

Of course your milage will vary depending on your spa size.
