I see a lot of check valves and two FlowVis (Vises? Visi?). FlowVises are check valves, so you might use that to eliminate something. And FlowVisi are based on Jandy check valve bodies, so unless you need constant monitoring of two full-time FlowVisiseses (there, that's right), you can simply swap FlowVis guts for check valve guts and move
one from check to check, to monitor flow as needed (but see next paragraph). Unless there is no budget, then Vis away! Wait, take that back. Checks impact flow, Vis even more so (because they have a stronger spring). So less is more when it comes to checks and Visiseses. And...
I had a hunch about it, so I asked here a while back and got it confirmed: the location of the Vis doesn't matter all that much. Flow is constant throughout the system. The
speed of the water through the various pipes and gizmos might be different, depending on diameter and fittings, etc, but the
amount of water actually passing by any given point in the system is identical to every other point. The exception would be if you used those bypasses other than just on-off, and were allowing water to split into two pipes. Then flow in just those branch pipes would be different. Otherwise, you really only need one Vis, in one spot. The two you show would be giving you the same number, no matter what the pump was doing, bypasses were doing, amount of dirt in filter, etc. The two would always read the same. Now the Jandy Max circuit would be different, and if you were determined to have two Visiseses, then put one in the main circuit, and the second in your Spa "Max" circuit. But, again, you need only to swap your one Vis into the Jandy check, unless you need constant monitoring for some reason. Now if you were backwashing, the two Visiseses as shown would read differently, but do you need to know that?
The IntellipH injector fits into a 1/2" thread, so I used a 2x1/2x2 tee and screwed it into that, rather than rely on the o-ring of the saddle clamp.
Neat feature: the IntellipH controller shuts down the IntelliChlor while it's dispensing. Presumably to keep acid from injecting into chlorine. Not sure why I like that as much as I do, but I think it's cool and something Stenner users can't match.
There's a recent thread by a guy struggling with his IntelliChem system. pH is fine, ORP is making him crazy. I think this is inline with others' opinion on IntelliChem. I've been running IpH and IC for a month now. Haven't touched either chemical. Awesome!! Took a very short experimental period to dial them both in and pH and FC levels have been very solid. And my wallet is considerably heavier. Even with an IntelliChem, I think it would be foolish to assume you get to test all that less often. I just don't see the benefit even it it worked well, which it doesn't seem to (at least based on anecdotal evidence). You'll pay a bit more for an IntellipH than you would for the acid tank you need for the IntelliChem (they are basically the same thing, with and without the motor), so I'd recommend you try the IntellipH and IC first, and see if they fit your need, before you pony up for IntelliChem. I think you can use the IntellipH tank with IntelliChem if you add it later. Based on the past month, I don't see any advantage to IntelliChem at all, except perhaps being able to control pH from ScreenLogic. The IntellipH controller passes control of IC on to my ET, so I didn't lose that function. But for some reason, Pentair doesn't have the ET managing the IntellipH controller, I have to go to the pad for that. Unfortunate, and the only thing I think lacking in IntellipH.
I don't agree about the sweeps. I say use 'em, get a little extra flow. No science, just gut. That, and the "Just Some Thoughts" section of
this article.
