How to Install Freeze Proof Sprinkler Water Supply

In this video I show you what's needed and how to hook up a sprinkler water supply for a cold climate that freezes in the winter. This is the plumbing and all the components that connect the main water supply in a house to the in-ground sprinkler box that directs the water to each sprinkler zone. This includes a water shut-off, pressure vacuum breaker/backflow preventer, valves, air blow-out locations, and sprinkler manifold and valves.

The best straight forward info. Thank you for the time you took in making this as easy as pie!

Glad you found it helpful! And thanks for letting me know!

I have an old copper irrigation system. what's the best and easiest way to rise the heads to the current grass level? The current heads don't even seem to be solder on the pipe.

@42Pursuit Жыл бұрын

Hmm, unfortunately I'm not familiar with that sort of system.

Great video! I am trying to build an automatic sprinkler system with 75 psi of static pressure, but only a flow rate of 5 gpm - the area I am trying to cover is around 3500 square feet of lawn. Do you know roughly how many heads or zones I should be running for a space that large? There's so many options. Thank you

Ah, that's a bit beyond me. I just figured out what plumbing was needed to get water from the house to the sprinkler box, the sprinklers and line had already been installed in this yard.

I’m in exactly the same situation as you. Would love to hear what you come up with.

@@AaronEsterling I followed Hunters Sprinkler Design Guide it provides a step by step process. Each sprinkler has a psi and gpm rating. Looking at your psi, gpm flow, meter size, etc provides what is called a working GPM. If you total the heads of the same type in a zone you keep it under that working gpm number. Not that hard… I also estimated pressure loss and there are some simple calculators for that as well.

Thanks for sharing. Why did you use galvanized instead of copper? Looks great.

@42Pursuit 3 жыл бұрын

I haven't ever seen copper used in my region so I thought it best to stick with what others were doing. I have seen PVC used as well, but galvanized seemed like the much more robust long-term option. Thanks for watchin!

One should never put copper fittings on galvanized pipe. A reaction of the two causes corrosion followed by failure. Thanks

Is the Black exterior pipe which goes to the box a pex pipe?

@42Pursuit 3 ай бұрын

It's a black polyethylene pipe. That style is the most commonly used pipe for underground sprinklers at least around where I'm at. I would imagine pex would work but it would be very expensive.

How’s the galvanized pipes holding up so far ? I’m trying to decide best pipe to use. Will galvanized rust with time or should I use pvc?

@42Pursuit Жыл бұрын

It's holding up great! In my opinion, galvanized is the way to go. It shouldn't rust and will last way longer than PVC which will degrade over time in sunlight due to the UV.

@ronaldlehman725 Жыл бұрын

@@42Pursuit the only problem with galvanized pipe is that unless you use a di-electric union to connect them to brass, the weaker material (iron in this case), will corrode away in a few years.

Why is there two shut off valves before the backflow?

@42Pursuit 3 жыл бұрын

One comes part of the assembly, and the other one inside the house is to shut off before freezing temps.

@noneya9013 2 жыл бұрын

@@42Pursuit Always leave the valves on the backflow preventers open at a 45 degree angle once it is blown out so not to freeze, damage or crack the valve. Thanks
