Seeing sand in your sight glass after performing a backwash cycle? Relax, It's perfectly normal! In this video I explain what's happening as well as give a quick demonstration showing the sand buildup as well as how to clear. If you're getting sand in your sight glass while rinsing or even sand flowing back into your pool watch till the end for possible causes and solutions.
Forgot to mention:
1. If you see excess sand out the drain port or in the sight glass during a backwash check your sand levels, you may have put to much sand in the filter. The central stand pipe should be marked with fill level.
2. If your sight glass is green/cloudy and you want to clean it switch the pump to closed (while turned off), unscrew the sight glass, and give it a good cleaning.
