Can someone with more experience shed some light on this question. Do SWG's fail slowly over time with diminishing chlorine output or do they just stop producing altogether when they quit? Is there even any rule of thumb on this?
I understood the expected lifespan of 5 plus or minus a year or so (roughly). If "seems" like it isn't producing like it used to, but there are so many variables, like lower CYA etc. And we are approaching the 5 year anniversary of the build and SWG.
I know we have some folks out there who are as OCD about their pools as I am so does anyone ever perform an overnight chlorine gain test on their SWG at different output percentages?
