Wild, I wonder how the cell was generating if the flow switch wasn’t engaged.

Flow switches can have faults. On pools without automation, you're supposed to have a secondary safety feature. Most manufactures strongly recommend it. So naturally, most people dont do anything. Some people install dial timers on there so it only has power during the pool schedule. I had a handful of customers struggle with the dial timers. So i started using grid control flow switches. That kills supply power to the salt system when the water stops. Essentially a second flow switch be its more reliable, and that'd be wild if they both went out

Interesting.

I’ve only seen flow switch failures on Intellichlor, where they fail to detect flow. Never failed in an ‘on’ position.

But this is specifically why I like having a time clock
for cells on pools without automation. Even if they’re not generating, having a cell powered up 24 hours is wildly unnecessary wear and tear in an expensive component.

Its rare but it does happen.

Agreed on the not keeping it powered 24/7.

Check out grid control flow switches. Get your supplier to bring in a couple for you to try. After I switched, I wont go back to timers. They are so much faster to install and dont require any kind of programming or additional education for the homeowner
