Re: leaving mechanical timer motor running during off-season
I can't prove it's better, but after a few experiences where motors failed to start in the Spring I started leaving the timer connected all winter. I have yet to have one fail since I started doing this, although I started over with a whole new pool (and timer) when the last one had about ten years of continuous use. The current one has been on continuously since 2004. My theory is that corrosion is the enemy, and continuous use keeps bearing surfaces corrosion free and motor heat from friction fights moisture accumulation. Truth is, in the 40 years I have had Intermatic timers in service at this location, I have never had one fail mid-season. It was always at Spring start-up.
