Stenner DuckBill Replacement

Here is a video on how to change out Stenner Duckbills

Duckbills are used with injectors to prevent backflow on systems. Not every body of water will need a duckbill.   Duckbills should be changed every time you change your Stenner tube. 

Steps:

1. Turn off water flow
2. Unscrew top fitting
3. Remove duckbill from top fitting with needle nose pliers 
4. Insert screwdriver into injector left in pipe to clear any clogs
5. Install new duckbill in top fitting
6. Turn flow back on
