The Fly High Check Valve Quick Twist Adapter is a two part fitting that replaces the Fly High Quick Twist / Sac Thread Adapter that comes with the Pro-X series sacs.
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.

Keep that water in check
If you like to keep your boat nice and dry we're adding tons of water weight this is the valve for you
Works As Advertized
Works well if you fill bags using the pump. I will buy one for each sack I purchase to avoid spills.
Great add for your portable fat sacs
No problem with water spills on fill and empty and the hose stays connected if you contort the hose correct like the other fittings. Also with the check valve it sucks the bag flat with very little water left to dump over the side.
They really do work
I was so happy with them that I bought another pair for a friend. It's nice that water doesn't get all over the boat, and with boat that still has a wood core, this was key.
Check Valve Doesn't Allow Any Water In The Boat
The Fly High check valve has a great design and it works just like it is supposed to but I didn't really use it after the first couple times. If you are worried about water in your boat this is the perfect tool for the job. The only draw back is that you need to buy one of these per sac.
A MUST HAVE FOR YOUR FAT SAC
The fly high check valve is a must have if you want to keep as much water out of your boat as possible. It is simple and easy to use. I haven't had any issues with the hose or pump staying attached to the check valve. Buy one today! You'll be pleased with your purchase.
Not happy with its hook up
The hose doesn't stay atttached to the check valve when filling or emptying it does its job as far as not allowing the water to flow out but just a pain to have to hold the connection in place the entire time have already removed it and just using the standard valve that came with the bags!
