Q & A

Q: Hi,i need a new cell and i don't know what sj unit i have. I have a in ground play pool 5ft deep if i get a bigger cell will it fit in my housing?

Asked by: Mike - 9/12/2017
A: Yes, all SJ cells fit in the same plumbing housing. You could upgrade to a cell as large as the SJ40 cell (SJ55 size systems have a special dedicated Control Module with more powerful components, so if you don't already have that size Control Module it wouldn't work.) In general, bigger is better because the system can create more chlorine with less effort and wear-and-tear, and is usually a better value.

Q: my sj-20 unit has about 9000 hours in use. How can I tell if it needs replacement?

Asked by: Fred - 4/6/2020
A: In general, if you get an warning light on the controller and you rule out the following, then its time to replace the cell: make sure your salt level is in range, the cell is clean, water is completely filling the cell, the water temperature is in the high 60's, and you have a good tight connection on the cell cord.
