How to drain a above ground backflow for your sprinkler system

[@deadpenguinss]

Did this last year, and my lawn-side ball valve chamber blew out anyway. Luckily, it just so happens when I fully open the valve it covers the hole so I didn't technically need to repair it. I'll be adding insulation this year. Thanks for the video!

Awesome video. Everything you need to know in two minutes. Great job. Thank you.

Oh wow very cool I’m in Austin about to prepare for our next winter storm thank you guys for this!

[@Hotshotutah]

Thank you for the video! Very helpful!

Good plan. Just draining the bfp leads to the bfp freezing on the pressure side. Need to be able to drain both sides down below the ground.

Thanks boys!

So I just did all steps, and there still water coming out from valve with no pressure at all, but it’s been running for about 20 minutes, is that normal? Does it take long for water to stop running?

Sorry for the late reply. You likely have fixed it by now but it sounds like the first isolation valve is leaking by.

This video does not cover every case. Not all states and or water providers allow the drain valves. This video was shared in my area and has cause more confusion than help. You should have stated that not all installs are the same.

Clinton, great point different areas may have different codes and drain valves. The video shows how they are generally installed around Austin, Tx.

Still has water in pipe. Poor design done here

Hi Michael. True statement. A below grade drain and isolation valve is definitely better. This is how most valves are installed around Austin Texas so that's why we showed the process like this. I think many installers thinking is it would be better for the pvc to freeze than the entire RP.

@@justinwilson1779 Yeah, same here in Houston. I’ve considered cutting the pipe and installing a fitting to clear the bottom.
