Cracked sprinkler pipe - how to fix?

My sprinkler system had a slow drip outside this winter due to a leaking ball valve on the supply line inside. I did have a plumber replace the valve but not soon enough as my outdoor PVC piping to my sprinkler cracked. I fixed that this morning and when I went to turn on the water to check it, I saw this leak..

What's the easiest way to fix this? I'd like to avoid calling a plumber again but my plumbing experience is limited to fixing an outdoor PVC pipe.

Do I need to replace that entire nipple or should I be cutting just the leaking part of pipe out and replacing that?

Thanks.

The leaking part should be replaced. You will need soldering tools. And unfortunately the heat from the torch will damage the seals in the two valves nearby so they should be removed before you sweat on the new section of pipe.

You could cut by the red line. Use a 3/4" sharkbite coupler, a short piece of copper pipe and a sharkbite male threaded fitting.

Thanks. I'm going to give the sharkbite a try. Just so I understand, I cut at red line at that would allow me to unscrew the threaded bit above. Then I thread in a new sharkbite piece, follow with copper pipe and then use a sharkbite coupler from copper pipe to remaining bit below, correct?

PJ is on the mark, but make sure when you cut at the red line that you are below the section of copper tubing that is expanded from freezing. Make the cut with a thin wall tubing cutter and deburr the inside of the tubing b4 sticking the Sharkbites on.

Wow...... very nice job.

Since you are a fellow NJian.... don't forget come fall the system needs to be completely blown out.

Thanks. I got lucky. When I cut away the damaged pipe, I had just enough pipe left on bottom to satisfy the depth requirement (15/16") of the Sharkbite. If the crack was a bit lower, I would have been stuck.

And yes, I did have the system blown out in the fall. Unfortunately, the slow drip from the leaking ball joint froze up and cracked the pipe. That will teach me not to procrastinate on fixing things when they need to be done..
