The correct way to repair your drip system trunkline

Even though a drip system, like the one I have at The Tropical Paradise, is low pressure, if the tiniest hole is created in the trunkline, it will spray out at high force. This doesn't happen often, of course, but here by a wall that I had repaired a while ago, it looks like the trunkline got nicked, and when I uncovered it to see what was wrong, I got "fountain hills"!

There are a lot of wrong ways to do this repair, believe me, I've tried. You stick "goof plugs" in, you can glop a bunch of silicone glue on the hole, you can try to wrap it up with electrical tape. None of these things work. Ask me how I know!

The correct way to fix this, and fix it right, is to replace a section of the trunkline. And the most important part is to get these cool 1/2 inch fittings. I've tried the simple "under pressure" fittings and they fail right away. These fittings, which I bought for a whopping $1.38 at Home Depot this morning, not only attach firmly, they have a screw top that cinches them down tight. It is ridiculously strong, which is what I want. This is a messy, muddy job, and I only want to have to do it once!
