Question

Connecting PVC Sprinkler Pipe to Copper House Main Line


Below you will find a picture of my current PVC lawn sprinkler feed connection to the copper house main.

The PVC connects to the copper with a threaded male PVC connector (lower left side of photo). The PVC pipe goes underground where it reverses direction and goes to the right - where you see the PVC valve. In the past I've had issues with cracks/leaks at the PVC to Copper fitting and with leaks in the PVC shut off valve (that's the current Issue I'm working on - note the pool of water below the valve).

I'd like to get some recommendations on a better solution.

A few question I have are:
1. Would replacing most of the PVC seen here with copper or brass pipe be more durable and less likely to leak?
2. Can a brass ball-valve shut-off valve be installed above ground instead of the PVC valve shown below-grade?
3. What is the best way to make the Copper to PVC connection? Is there a copper-to-PVC union I can use? The PVC threaded male adapter has been problematic.

Note: I live in southern California so freeze/thaw isn't an issue here.

Note: I added annotations to the image.

You need a backflow on that mess...
2. Your suppose to blow out the sprinkler lines over the winter.

Backflow may save your families life...

Have a good day.

Thanks for the replies.

Ghostmaker:
* The sprinkler valves have backflow prevention built-in. Do I still need backflow between the main supply and those valves?
* It never freezes here (SoCal) - is there still a need to blow out the sprinkler lines? I occasionally use my sprinklers during the winter months - it was particularly dry this year.
* Why would backflow save my families life? What is the danger?

Javiles:
* Is schedule 80 PVC ok for above-ground installations?
* Will would you do a SCH 80 PVC shutoff valve too? or put in a brass ball-valve and then go SCH80 PVC downstream of that?
* What would you use to connect copper to the SCH80? A union, or a threaded SCH80 pipe?

Sch 80 above below OK use a brass ball valve, what you want on that line is a vacuum breaker, I think what ghost means is these back flow devises keep out cross contamination people have gotten sick from dirty water mixing in with their drinking water. yes it dose happen more often then you might think. you also need to make sure the pipe is 100% secure and will not move, shake, vibrate, etc, if it does you will always have problems with threaded connections.

What you need is one of these,

Have the copper go in through the bottom and the PVC out the side. Must be mounted 10" higher than the highest sprinkler.

It doesn't seem right that the sprinkler take off is ahead of the pressure reducer and the main valve for the house. I am surprised that there is no back-flow preventer right at the water source. Around here the back-flow preventer must be immediately after the shut off.
