Specs

Best For: Maintaining Strong Suction & Cleaner Efficiency

This seal flap kit is ideal for pool owners who rely on the Pentair SandShark for consistent, hands-free cleaning. Over time, seal flaps can stiffen, warp, or tear due to constant water flow and debris impact. Replacing them restores the internal water channeling that helps the cleaner hug the pool floor and walls while capturing dirt effectively. It’s especially helpful if you’ve already confirmed proper hose length and suction levels but still see performance issues.

Best for: Pentair SandShark cleaners with reduced suction or missed debris

Not ideal for: Pressure-side or robotic pool cleaners

Our Expert Verdict: A Small Part That Restores Big Performance

In real-world pool service, seal flaps are one of the most overlooked wear components on suction-side cleaners. When they fail, the cleaner loses efficiency—even if everything else looks fine. The Pentair GW7913 Seal Flap Kit brings your SandShark back to proper operating condition, improving debris pickup and cleaner movement.

At ShastaPoolSupply.com, we recommend staying with genuine Pentair replacement parts for reliable fit and long-term durability. With fast shipping and expert guidance from Arizona’s most trusted pool professionals, you can maintain your cleaner with confidence.

How often should SandShark seal flaps be replaced?

Seal flaps should be inspected at least once per season and replaced when they show signs of cracking, stiffness, or deformation. In pools with heavy debris or high run times, they may wear faster. Replacing them as part of routine maintenance helps ensure your SandShark continues operating at peak cleaning efficiency.

Expert Comparison & Pro Tips

Compared to aftermarket replacements, the Pentair GW7913 kit provides exact fitment and material quality designed specifically for the SandShark’s internal design. Generic seal components may not flex properly, which can impact water flow and cleaner movement. Maintaining OEM parts helps preserve the cleaner’s original performance characteristics.

Pro Tip: Before installing new seal flaps, inspect the cleaner’s footpad and turbine for wear. Replacing multiple wear items at once can dramatically improve overall performance and extend the life of your SandShark.
