How to Drain Your Sprinkler Backflow Preventer in Texas

- Matt from Texas Edge Home Inspections goes over how he drains and winterizes his sprinkler system backflow preventer to prevent freeze damage in the winter. This method has proven to be fail proof in the Houston Texas area even during the hard freeze of 2021.
Exactly the directions I needed; thank you for posting this how-to reminder.
Thank you for getting straight to the point.
Excellent instructions, thank you!
Thanks for the tips Matt, really helpful
Good suggestion, the way I do mine, since the two blue handle valves on the backflow protector are froze open and unmovable, is turn the inline valve found between the water main shutoff and the backflow protector (found in the ground) off then drain the two pit valves on the backflow protector. If a person should try to force open/close the blue handle valves, they might break the PVC pipe.
Great video
I have a valve at the base of the system. Should I open this when I open the system in warmer weather
Thank you
We know you meant 2021 😎 potato, potahto
😂
it would have been good to tell that you are in Spring (Greater Houston Area) as folks in Dallas probably need more protection
People NEED to use discretion on their own circumstances. I have lived in both Houston and Dallas however and there was not that big of a difference typically except a few snow days 🤷♀️
Thank you for sharing this.

Yeah, lol. I know. And I did it twice! I didn’t notice until the video is already edited and posted so unfortunately, it’s just gonna have to stay that way. What can I say? I am human.
You didn't explain what value cut off you turned off first. What is the horizontal value?
You should turn the water off the valve of the meter. Water is trapped in the 1" valve and exposed will surely burst
That’s not how it works. If you turn off water meter, turn off water to the entire house. If you were to turn it off at the meter, and then drain your sprinkler backflow, then turn it back on, you would be in the exact same situation. Trust me, I do this every single year and have four years. There may be some extra precautions you need to take in other parts of the country but here in Texas, or at least in the Houston area where I am located… This is how you do it.
@@texas.edge.inspect I'm in Houston as well. What I meant is to turn off the valve if there's one coming from the meter the backflow. Then draining and leaving the 3/4" valves open so in case it freezes they won't burst. I did as you showed and covered everything with blankets and a bag and the culprit where the 3/4" valves. Cold air still got in somehow and made hairline cracks there. This year I'm literally cutting the PVC and taking the whole enchilada inside for Christmas with me😂
Are you from Goliad, Tx?
1st and formost the water to the vacuum breaker needs to be shut off or the water will sit at the ball valve on the bottom and can freeze and crack and split i wouldnt listen to this guy. He doesnt even the know what hes talking about. Very dangerous if thats all you do, at least here in michigan.
You may have trouble listening. Lol. I’m in Texas. This is what I recommend for my area if Texas. And, as stated, I do not have a valve to the back flow preventer. It’s best to have one and shut that off but I don’t have one and many here done. Also, I have done this method for 8 years and while all of my neighbors have had to replace theirs…multiple times. I haven’t ever had an issue. It’s best to blow it out with an air compressor but not everyone has one or knows how. This method works very well…HERE. Definitely not in Michigan. I speak from experience
