Hunter Check Valve for PGP-ADJ Ultra and I-20 Series Rotors 142300

Fixed the leaking head.

Installation is easy, worked as described preventing draining of its supply line.

Stops the sprinkler that leaks out when it’s the lowest sprinkler head.

It does what it's suppose to but after closer inspection I realized I can add the rubber flap to my existing filters. Which I did and that works perfect. I used an old tire tube for material for the flap.

I have had a sprinkler head that’s been leaking for a couple of years. I replaced the sprinkler last year and I was convinced I had a leak somewhere in the line. In researching I came across this item and I’m so freaking glad I tried it! I had to watch a YouTube video since instructions do not come with the product, but it was easy to install, and instantly stopped the leaking.

Haven't installed them yet, but they look like the right part. Packed well.

Item was just as described. It worked perfectly.

This plugged the sprinkler head to aerobic septic system. Since my hard is on a slop all the lines would flow back after pump shuts off. I placed this on the head closest to the pump and no more back flow (leaking out head).
