5 Steps to Find Suction-Side Air Leaks With the Hose Trick

Run the pump and spray a garden hose over suspect fittings and joints. If water seals the leak, air bubbles in the pump basket will disappear, revealing the exact spot.

Focus on common failure points first. Check the pump lid o-ring, drain plug, valve stem seals, and any threaded connection before the pump.

Work in sections from the pump back toward the skimmer. This systematic approach prevents missing leaks and keeps the search efficient.

Have a helper watch the pump basket while you spray. They can immediately signal when bubbles stop, confirming the leak location.

Use a gentle stream, not a pressure washer. You only need to create a temporary water seal, not blast debris. Once found, replace the o-ring or tighten the joint.
