  1. I replaced my Hayward T15 with new pureline and it came with new screw fittings but i would have to replumb to use them. the Hayward fitting seemed to wirk fine but it apparently backed off and was leaking. i made sure it was not crossfit but when i tightened it the threads are not tight and it acts like it is stripped. Anything I need to do other than rework the plumbing? the new unit did not come with the part that holds the tcell

    1. Teflon tape can be used to try to secure the nut in place. Outside of that, I am not sure of anything else that may work other than doing the necessary plumbing to use the fittings that came with the Pureline.

  2. I have a system with a T-5 cell, the brain AquaTrol appears to be working correctly.
    The T-5 cells seem to be harder to get, it states my brain is compatible with T-9, T-15.
    so I am on auto, push the diagnose button through different setting, but the cell page (8 button pushes) isn’t there.
    After the 7th push it goes back the the main salt page reading.
    Am I missing something?

  3. My cell voltage is working it’s way up to about 19, the generating light comes on, then the voltage drops to 0, the generating light disappears, and it works it’s way back to 19 again. This is a neverending cycle. Any ideas?

  4. Hi, I am using the low salt system from Hayward the cell number is LS-CUL can I replace it with T-Cell 9 or 15?

        1. Not sure what you mean by smelling ‘gad’, sorry. Gas?
          The cells look identical – I assumed that the the differences would be in the logic board and not the cell. I do not want to damage the board or do anything dangerous.

          Are the cells interchangable? Thanks

  5. I recently purchased a new T-3 cell. When I tried to recalibrate the system and scroll through to the tcell display, it does not appear. I have no idea what the system thinks it is operating on. Why is the display to change the tcell not showing?

  6. I had someone install a salt cell but they put in a T-3…when I checked to see what options I had on the board it was only T-5 or T-15…can I set it at T-5?

    1. You can, but it isn’t going to have the right voltages, amps, and salt readings to match what the TCELL3 is going to provide it. You should have them put in the same cell you had before.

  7. Hi
    We had problems with our cell…
    So we bought a new one!
    I would like to know if a T Cell 15 is compatible with a older version aqua nature?

    1. There is not much information on AquaNature; but it looks like a private-label version of an AquaRite / AquaLogic system.A couple of questions: is this for an inground or above ground pool? What was the cell part number of the original cell?

      In the future, you want to ask “is this compatible” before you purchase the product. Measure twice, cut once.

  8. We have a t-9 right now. Our pool is around 13,500 gallons. Is there a benefit to purchasing the T-9 (25,000 gallon) or can I change it to T-3 (15,000 gallon).

    1. Each cell size is rated for a certain amount of chlorine it can produce; the larger the cell the more chlorine it can produce in its lifetime. With that said, if you go for the smaller cell, you are going to have to replace the cell sooner, which may end up costing you more money in the long run.

  9. Are specs different for the T15 cell than the LS cell? They look identical so I am assuming the difference in units is in the circuit board of the main unit. I have a T15 cell that is brand new, and while the LS cell I have is working well, I wondered if it stopped, could I use the T15 in a pinch?

    1. I have found differing opinions on whether the TCEll15 would be compatible with the low salt units. Because the low salt variety is kind of rare and fairly new there hasn’t been much tinkering with it. There are two routes you can go: call Hayward, the manufacturers to see if they have an opinion, or you could just try plugging it in and see what happens and give us all the answer.

  10. I just went to buy a T-Cell 940 to replace my Tcell15 in my Hayward aquarite system. After a few days, I opened the box and realized I was sold a Hayward Tcell940SWP. Will this cell work with my system or do I need to go fight for an exchange?

    1. It appears it should be compatible. I presume the SWP just means SwimPure which is the model that cell fits to. But you can always try contacting the dealer from you purchased it from to have them confirm they sent you the right thing.

  11. I am a pool service tech. I have used a Regular T-15 Cell’s in Lowsalt systems for years with no issues. If anything the cells seem to last longer. My ow pool was originally a regular Hayward with a T-15 cell. I swapped out the main bias to a LS board over 8 years ago and am still using the regular cell.

  12. If you use a t15 cell for a low salt machine then what setting do you use for cell type. My low salt Hayward chlorinater is Version 1.00 and only allows me to choose between AL-0 up to -5?

    Any thoughts ?

  13. I’m very confused by this article, because your Pureline PL7106 description for the TCell-15 says it requires software 1.5 or higher, but this article says that the TCell-15 works with ANY version….which is it???
