Sprinkler system underground leak help
Yep, got a leak somewhere. Did the timing thing with the water meter
and found the three largest zones use most of the water. My Problem: water bill came to $400.00 one month and $500.00 the next month. Stopped using the sprinklers and dropped to $50 - $60/Mo. My Guess: underground sprinkler leak My Question: What is the easiest way to check the lines for a leak? My Answer (up for review): Take out the sprinkler heads in each zone and cap off the line, run the sprinkler water and see if meter turns. Need help to see if this is the best way to check the lines, or will a divining rod be better? Any comments would be greatly appreciated. Dave FL |

Dave FL Find the swamp in the yard caused by the thousands of gallons of water your system seems to be wasting. Beyond that, capping all the heads and running the whole system to locate wet spots in the yard is about the only thing you can do. But eesh, with that much water you'd think the problem area would be soaked enough to sink into when walked on. |

Haven't noticed any swamps or really wet areas around the sprinkler heads Beyond that, capping all the heads and running the whole system to locate wet spots in the yard is about the only thing you can do. That was my thought too. But eesh, with that much water you'd think the problem area would be soaked enough to sink into when walked on. I agree, I also plan on getting rid of this St. Augustine grass & replace with Bahia. Dave FL |

They could be anywhere the line could break. But if your soil drains well then it's all together possible that it's draining off. But at that much usage, wow. ID where your lines run from start to end so that you can check the whole route as it's not just about the heads. When you cap everything and run it for a while, walk the line and see if you can pinpoint any problems.. A moisture meter may help, check every foot or so for a reading after it's run for a while. If you're lucky you'll be able to narrow it down to digging up a few feet at best to fix. Either way, good luck on finding the problem... |

If you're lucky you'll be able to narrow it down to digging up a few feet at best to fix. Especially with almost a 1/2 an acre Either way, good luck on finding the problem...- Thanks, Dave FL |

Dave FL With a leak of that magnitude there would be a very noticable loss of volume at one of more sprinkler heads, have you ever taken the time to observe each head through the entire cycle? Of course your leak could easily be somewhere underground other than the sprinkling system.... I had a house with a cubside water meter and the leak was after the meter but before the pipe entered the house... no surface wet spot but by standing outdoors near the curb I could hear it as plainly as when a toilet is running. |

I have left both of them on (1-interior & 1-exterior) and turned off the rain bird system and it used no water. I can go to the PDV valve to bypass the control so I know there is constant water to this point. So my leakage must be after the diaphram/solenoids. Dave FL |
