DO NOT BLOWTORCH THE PIPE! This can damage the plastic and cause the fitting to blow off the pipe.
If you have an ACTUAL lawn, just multiply this installation by approximately 5,000%
“Backflow preventers” are a complete scam! Common sense and gravity say there is no way for dirt to swim upstream 80psi inside your pipes and out your sink!
Its called an Otiker Clamp.
What is a hose bib? That is a water faucet.
I’m sure this guy has a “numba on the Sawx”
Doesn't it rain enough in Boston?
Backflow preventers need to be installed before you connect the battery operated sprinkler system to the water supply, not after.
Just curious, how come the heads don’t need a clamp also ?
How do you drain this so it doesn’t freeze in winter?
Me: finding videos on this for my boyfriend
Boyfriend: “needs to be IN NEW ENGLAND SPECIFICALLY”
Me: plays video
Boyfriend: hears accent for .1 second and says “perfect”
😂
How do you know that you have 10 gallons per minute?
I was waiting for the guy to call me numb nuts the whole time
This is out dated
How do you know if the zone stays under 10 GPM?
Stabs spade shovel in the ground…….breaks main water line. Way to go Kevin.
Good video, clear to the point without too much wording. Well done, thank you!
So many things wrong with this install. If you wanna run off a house big buy yourself a soaker hose and put it on that cheap timerv call it good. There is no reason to run 1inch pipe off a hose bib which is 5/8. Also using all 10 gallons per min leaves you nothing left for the house.
Would love to see This Old House do an update of garden irrigation. There are drip systems out there one can get at the local home improvement stores……. Questions…how easy to install and are they good for my periennal borders….Is drip most water efficient, etc.
i like PVC better
