Works like a charm! In-ground pool OK!
on February 6, 2015
You CAN use this on an in-ground application. Needing to replace our salt-chlorine generator (SWG), I did lots of research on the internet and in my local stores. Prices were $950 to $2000. I can buy a dump-load of chlorine for that money plus replacing salt cells every two or three years. Fuggedabowdit.
I bought this on Amazon for about $130 and change and was very skeptical. After all, it's more than $800 cheaper than the nearest competitor and I've never used the Intex brand before. All the reviews are great but most of the users have above ground pools, for which this is designed. That said, it's because Intex makes parts almost exclusively for above ground and not in-ground pools.
Installation was very straight forward and so far my only complaint is the layout of the inlet and outlet of the device. Why make a 90-degree turn on the exit? It added several turns to an otherwise clean installation. If that's the only problem then I'm happy as fleas on a mongrel. The threaded input and output ports are standard 2" NPT so just use a couple of female adapters and then you can glue into your plumbing from there. Wrap the threads with at least 6 to 8 turns of quality PTFE thread tape. Do not use pipe dope.
For "permanent" installation (it comes with a three-prong plug with a built in GFCI control), all you need to do is clip the cord before the GFCI and mount the cord to your J-box with a UL strain relief in a 1/2" knockout and add to your existing protected pump switch circuit.
Programming was very easy - you just tell it how many hours to run per day. Wire it so that it is switched with your pump and you're golden! Just make sure that your pump cycles for at least the same if not more hours than the SWG.
There's a bit of guess work at first as far as how many hours to run but if you have even a little knowledge of SWG systems (read, baby, read) then it's very simple to get started. Monitor your levels daily at first and weekly thereafter, adjust as necessary. Now, let's get Intex to start marketing equipment for the rest of the world who have real pools!
