I have 100 ft of 1/2" drip irrigation hose (two 50' lengths, connected) with a proper regulator running through my vegetable garden. The first 50' of hose only works till about halfway down the hose and then the emitters are dry, not working at all. As previously mentioned, this hose is connected to another 50' line and that hose is working perfectly so I'm not sure why the middle group of emitters isn't working!?!?! This spring when I set up the system, I found a kink in the hose at the spot where the emitters aren't currently working, but I fixed the kink (and the second section of hose is working so the water is obviously getting through...soo...) what could it be? any tips/insights would be appreciated! thanks
