My water line dropped 6 inches 2 days ago and stayed. It's always maintained it's water line so I've always assumed there is an autofill. I was hoping you could suggest a way to tell if the autofill is working correctly. I was going to fill it back up with a garden hose but then I figured I'd never get to the bottom of the issue if all is working correctly now.
The water line is now just below the skimmer but the drains are still sucking water in and the returns are still pushing water out at a steady rate. There is a spa spillover that is working too.
When I first noticed the issue the spa wasn't spilling over either so I adjusted the valve at the pump so that it would. Is this a sign of something as well?
