How long doe a SWG cell last. I assume it is supposed to be catalytic only but what is the practical life for a cell? I heard of many people going to salt system/SWG only to go back once they find out the expense of a replacement cell.
How long does a cell last?
Way too many variables to say. Some people only have the pool open 3 months, others year-round. How many hours a day does the pump run? How big is the pool? How much sun? What is the CYA.? What percentage is the SWG set? Some check and balance their water chemistry very carefully, others don't even know what CSI stands for.
That said, with proper attention and care, there is no cheaper way the chlorinate a pool. My T-15 cell lasted 7+ years in a 19,000 gallon pool where the pool is open year-round and in use from April-November. I then replaced it at a cost of $400. That's less than $60 per year for my chlorine.

In general, when sizing an SWG for a pool it should be sized for at least twice the size of the pool so that you have both reserve capacity and you can still generate enough chlorine when shortening pump run time. Otherwise, you are forced to run the pump longer just for the SWG. For a 40k pool, you should have at least an 80k unit or 2 x 40k units. But with an ePump, extending run time it isn't so bad as long as you run at low RPM. But you are still using more energy that you really need to.he couldn't understand why they installed two units.
