The Importance of a Check Valve Flapper
The check valve flapper is a small part with a big job—it keeps water flowing in only one direction. Without it, you risk:
-
Pumps losing prime when the system shuts off
-
Heaters firing without proper water flow, causing internal damage
-
Water draining from raised spas, fountains, or other features
-
Air entering the system and causing inefficiency
Installing a fresh Swimables SW-35-056 flapper ensures your pool system remains protected and operates as intended.
Signs You Need a Replacement Flapper
Over time, constant water flow, chlorine, and salt exposure wear down check valve flappers. Replace yours if you notice:
-
Water flowing backward when the pump shuts off
-
Air bubbles in pool returns due to backflow
-
Water loss from raised spas or water features
-
Cracks, swelling, or visible wear on the flapper
-
Increased noise from the valve housing
The Swimables corrosion-resistant flapper is designed to handle these challenges and restore reliable performance.
