Hayward T-Cell 9 vs. T-Cell 15

[razorhawgfan]

My salt cell has stopped working and I’m researching to buy a new one. I currently have a 15 but I’m seeing the 9 is a little cheaper and it will service pools up to 25,000 gallons. My pool is roughly speaking a 20,000. So I’m confused why the builder would use the 15 to begin with. Anyways can anyone assure me that the 9 will work? I’m thinking it should be fine but I’m not an expert on this stuff. Thanks!

The larger cell is usually a better deal economically because the T-15 will last longer.

The T-9 would have to be less than 60% of the T-15 cost to make it worthwhile but that does not include any extra pump runtime either.

We recommend a SWG to be rated for at least 2 times the pool volume.
The rating listed for a cell is if run at 100% 24/7.
Stick with the T-15 cell for your 20k gallon pool.
