Another is to swap out your 2 gph emitters for those with lower flow rates. One solution is to divide that line into two separate zones. What is going on? It sounds like you have too many emitters for the 240 GPH carrying capacity of your 1/2" mainline tubing. My water is clean and I am using a filter. They are supposed to be 2 gallons per hour (gph), but some of them are only dribbling. I have a bunch of emitters on ½" mainline tubing. If the hole still leaks you will need to cut out the leaky portion and insert a coupler that matches your size tubing. How do I fix this? First try a two-sided goof plug (14GP2) which has a standard sized plug on one end and an oversized plug on the other. I had a leaky emitter which I replaced with a goof plug, but it still leaks. We suggest a pressure regulator after the filter. What could be wrong if emitters and fittings won't hold tight and keep coming off? Likely, your pressure is too high. A water filter is insurance even with "clean" water and a regular cleaning of your filter is recommended. Sounds like a system with a dirty filter or no filter. What could be wrong if less and less water is coming out of my system?. If the leak persists, replace the O-ring or see whether there is another source for the leak. Re-assemble the filter and put it back in service. What if water is leaking from the body of my filter? Open the filter, remove the O-ring, and clean it, the groove it sits in and the surface it mates against. If your flow exceeds those numbers, your supply is being over drafted. Our 1/2" tubing carries 240 gph 3/4" tubing carries 480 gph. Add the maximum flow rates of the water dispensing products on the line. What if water comes out at the beginning of the system but not at the end? There's a good chance you are using more water than your line can carry.
