We had a pool installed back in 2012 with a Hayward Aqua Rite SWCG. I bought the T-15 cell under the advice that a more powerful cell working at 50% would last longer. It's rated for a 40,000 gallon and the pool is only about 17-18,000 gallons. So ather only 3 seasons it's not working. I confirmed this by calling Hayward and they had me run through the diagnostics on the control panel. So my question is what brand & model do/did you have and how long did it last? Also if you went with a different brand cell to replace it, what name, model and how much longer or shorter did it last?
Thanks
