I am wondering if you guys removed your chlorinator and installed the swg where it is? I do not have a lot of space to put it and was thinking that was an option since the swg would be used while away (only use chlorinator while away)
You have a couple places where there are long enough runs for a SWG cell and flow switch. My first choice would be just eliminate the tablet chlorinator and put it there.
WOW you deserve an award for that pad. I won't say what the award is but you deserve one.
Yes you can replace the tab feeder with the SWG. It will work fine there.
That is all well and good if you have low debris in the pool.I can see a slight advantage for using filtered water to supply the booster, but mine was right next to (and shared it's supply with) the main pump, and it was never an issue. I don't see any reason to replumb anything re the booster pump.
