The Fly High Check Valve Quick Twist Adapter is an optional upgrade for Fly High Pro X Series ballast bags that replaces the standard Quick Twist Adapter. Just as easy to connect and disconnect as the standard fitting, the W744 Check Valve adapter also features an integrated check to prevent water from exiting the bag when disconnecting and connecting the pump for filling or draining.
Don't worry about water shooting back into the boat when you disconnect your Fly High Tsunami pump. Fill the sac normally using the twist connect system. When it is time to drain connect the included fitting on your pump to push through the rubber diaphragm and allow the water to come out.
If you want to keep your boat as dry as possible, this fitting is definitely for you, just remember that you'll need one for each ballast bag.
Fly High ballast fittings have been designed with you in mind. All of the fittings make connecting pumps and hoses to your Fly High Pro X Series Ballast Sacs™ a quick and simple task. No more struggling with old waterbed valves and water spilling inside the boat. Simply twist, pull, replace and you're ready to go! Fly High offers several different fittings that all work together to adapt to any of your needs.
