Thank you so much for providing this video tutorial for inexperienced people like myself who knows nothing about back flow preventer. I drew the valves on a piece of paper how they need to be positioned on the unit in order to be drained. I followed your instructions exactly like you said, and the back flow unit has stopped dripping. The plastic piece on top of the one way valve broke due to the freeze, and I was in panic mode, water was pouring out. This was a very easy and simple video to follow. THANKS!!!!!
If you do not leave test cocks and ball valves on the backflow preventer at 45deg they may still freeze as they trap water when fully on and fully off...
Excellent explanation.
You're a home saver thank you for this video

We can only see this straight on. We need to see the side view to make clear understanding.
My system doesn't have that drain at the bottom
great video
This would be helpful to send at the end of every season

I believe some systems don't have that kind of backflow prevention. Only a water meter under ground in a box.
So you don't need to shut off the two backflow prevent valves?
Thank you for clearly and slowly explaining how to do this for us women.
u dont want the pipes to shiver and brake
Very simply explained for a dummy like me! I just did it! Thanks again.
