How do I check for suction leaks?

Suction leaks can cause a whole host of problems, such as a pool cleaner which doesn’t work even after backwashing, the persistent growth of black algae, or bubbles streaming out of your aimflow. If you are experiencing any of these issues, check for suction leaks. Have a look at your multiport valve o-ring and pipe joints, your pump lid o-ring, your pool cleaner hoses and your underground piping. Finding leaks is usually the biggest part of the job and once you have located your leak, it can simply be sealed tightly to ensure that air bubbles no longer disrupt functionality.
