I have a small backyard and I am tired of moving hoses, etc to water the grass. Is there any reason why I shouldn't bury pvc pipe and add probably 3 sprinkler heads which I can then connect to a Y valve on my hose spigot?

1/2" pipe should be sufficient for 3 heads right? Less than 150 feet of pipe.

No input on your specific question, but another option is these burried sprinklers with quick connects. I don't own any, but my neighbor has his yard set up with them. He also has a jumper setup with a y-connector to hit 2 of the heads at one time.

That's a cool idea but would still have to mess with the hose.

After looking a bit more, it looks like I can use polyethylene tubing made for irrigation sprinklers instead of the hassle of PVC.

No, there's no reason why you couldn't or shouldn't. What you are describing is no different than a normal irrigation system except it is tied in through a spigot rather than from your mainline. We did the same exact thing but for our front yard. The process is straight forward - the only trouble we ran into was that we had to go underneath a sidewalk and work around some roots.Trenching by hand is a pain though so you may want to look into renting a machine if you have 150 linear ft to dig like we did.

Be sure to install a backflow device on the spigot before connecting the Y connector!

You can do this but it is technically illegal because you don't have a backflow preventer on an irrigation system. Make sure you have a vacuum breaker at your hose bib at least.

Great minds think alike.

So if I am just connecting it like I would a normal water hose, why would I need the backflow preventer? I mean I don't need one when I hook up a hose and run a sprinkler.

What am I missing?

For 3 heads and 150 feet, I'd opt for 3/4" pipe. You'll never regret having the capacity/flow rate.

By current code in most places, all hose bibs should have a backflow device as it's one of the first things inspectors write-up during home sale inspections...ask me how I know! Two houses, two write-ups!

Anyways, all you need is a cheap device like the one below that you can purchase at your local Walmart, HD or Lowe's stores...

These are required by code now on all hose bibs. The most important part of any irrigation system is the backflow preventer. It keeps you from contaminating the domestic water supply though back siphonage or back pressure.

I have a biggish lot with no irrigation and I've been looking into this as well.

I'm leaning more toward a couple of these. With a vacuum device on both of course.

What you're missing is that your proposed system will be buried (Permanent) versus hose and sprinkler. If it is "temporary" irrigation then you are good. I have a rent house currently and I ran some pipe in the front yard to connect to hose bib. When I'm not using it I disconnect it from the hose bib.

Gotcha. Thanks for the replies. I'll grab one of those to throw on the line.

So wound a back flow preventer be required for inside faucets, dishwashers, etc.?

No, just exterior cause you don't want to get chemical contaminates like fertilizers, weed killers, and poisons from hose end sprayers, etc to backflow into your water supply!

The backflow preventer on a faucet is the air gap between the faucet and the container.

Dishwashers and washing machines have backflow preventers built in.

Did this last year with great results. Wa able to cover my whole backyard with 3 big rotors thanks to having high water pressure. I put a hose bib in the ground inside an irrigation box and have a battery powered timer running it for me.

I would recommend using funny pipe over pvc much easier install with out the connections to worry about.

Watch out with restricting flow
