Inline one way valves

I was wondering if anyone had source for Inline one way valves like Klystra used to sell. They are placed on a enema hose and they prevent back flow from coming back up the tube. I Like them because they enable really low slow enemas.

You don’t need a specialist supplier for this kind of thing. Just look on ebay. I have bought such items from https://www.ebay.com.au/usr/maxtechshop, but there are many others.

Silicone Nozzles has these for $6.00 I believe this is what you need.

Check Valve Anti-Reflux Large One Way $6.00

Why not just hang the bag at a normal height and crank down the valve/clamp?

You can buy a one way bulb from the boating supplies area of Walmart, or Home Depot. Attach tubing to both ends and you're ready to go. Also available at optimal Health Network.
