Great video! This is the correct way to install a pressure regulator. If someone is in a pinch and can't afford to install this. My suggestion is to simply crank down on your shut-off valve instead of having it fully open. Test the pressure after the valve and regulate accordingly.

Have installed numerous sprinkler systems over the years and your video gave me a few tips I was not familiar with. That is the difference between a professional and a backyard you.

Thanks. Great video. Seems that attaching this to the street-side of a removable backflow assembly would be ideal; after the cut-off valve and before the backflow assembly connection..

Love the information. What PRV valve is that? I'd like to buy the same one or can you recommend a good one that you've had success with? Thanks

Wish the irrigation supply store wouldve told me about the Teflon glue! Damn it! Now that wouldve saved me loads of frustration! Thanks for the info and save! Now to start over. Again!

Gary, thanks for a very informative video, it's helping me to address problems with my ornery drip system. I have this question: Theoretically, if I have two 1" PVC pipes carrying water, one at 20 psi and the other at 30+ psi, will there be any difference in the amount of water that passes through them in a given time? would the pipe with higher pressure carry more water? Thanks for your response!

Great video Gary! I am just learning that my system probably was never done correctly. I added a PRV (set at 50psi) to my sprinklers because I had hammering and noisy lines while running. The pressure was 110 coming into the house. Now it hammers more and is quite noisy while running. (air?). The PRV is installed after the backflow valve. One zone is noisier than others. It looks like the house PRV (separate) might not be working either. Confused and would appreciate your advice.

This was useful. Thanks for posting this video.

Thanks for the video! Can I install it vertically and just after backflow preventer??

[nskmda]

so, this might b a SECOND PRV, right? because my system is connected directly 2 the water main, before the house's PRV. And I have a lot of water hammering when sprinkler valves open.

Nicely done... I was worried you weren't going to use a valve box/cover at first when I saw the shallow trench :-)

I received an estimate to install a PRV due to installing a drip system on my side slope landscape. The person quoted me $450 just for installing the PRV. Is the estimate too high?

[mikemorris]

Can you get a pressure regulator valve down to 10 to 20 PSI in that style?

[edcano]

Is the pressure regulator the right application to prevent water hammering?

[fwoodman]

Where are you located in CA? Can I hire you to do this job for my home sprinkler pressure regulator?

I wish, I’d be giving it a trip to the jewelers.

So do you think the orbit 3 valve manifold needs a certain pressure to ensure the valves dont get held open from water pressure on the line?

[GeezerAppeaser]

Awesome video! I recently had a pressure regulator installed on my irrigation system due to water hammer. But now the water pressure for my backyard sprinklers is too low. I noticed the PSI on the regulator is set to 35. What PSI would you recommend to get that water pressure back up to where it should be? Thanks!

Gary, where can I find a pressure regulator? Ewing? Do I need to go to a plumbing supply?

At 12:31 it shows that a cut is made right over some dried cement or primer from the last install. Can that cause problems assembling your new fittings? I usually cut in a clean area to be safe, but maybe I'm being to cautious?
