SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Hi, I'm new here. Recently started working on fixing my backyard irrigation system. I have an old (maybe 5-10yr) drip irrigation system that I've been trying to figure out how to fix. It's controlled by an anti-siphone valve timer. The water pipe (underground) branches off to two sides at the t-shape coupler, left and right. I've been trying to figure out why a section of the system does not seem to have enough water pressure to drip.

I started digging today and found where the water branches off. At the coupler, I discovered that there is a tiny hole designed in the coupler that keeps leaking water. I wonder what this is and I wonder if this is the cause for loss of water pressure. Here's a picture of the coupler underground. You can see that next to the word PD-84-25, there is a tiny hole (white dot). Any help is appreciated!

Hi Wet Boots,

Does this regulator replace the T-shape connector or the coupler below the connector?

Thanks again. I guess there is some work to do for the next few weekends!
