I was having issues with some of my Hunter PGP-ADJ sprinkler heads and from watching YouTube, it seems to have been a low drainage issue where the last couple sprinklers at the lowest point was leaking water after the zone was finished. It seems I needed to add an anti-drain check valve to to sprinklers because the ADJ comes standard without the rubber gasket. I ordered these and this resolved my issue! No more leaks at a very low cost!! Thank you all at Sprinkler Supply!!
