I just recently had to do some work on my main sprinkler shut off. All went well but when I turned my house water back on (had it off from the street and in the house) our pressure is low. It's a bit down everywhere but it's very noticeable on our fridge dispenser. I tried disconnecting the line and letting it drain in case there was air in the line. Any ideas?

  • Disconnecting and draining the line seems to me like it would put air in the line. Commented Jul 11, 2018 at 21:12
  • There's a leak in the sprinter piping, mst likely before the valves, allowing a lot of water to escape. Did they put a cut off valve to stop water to the sprinkler system? If so shut it off. Commented Jul 11, 2018 at 21:16
  • I was worried air had gotten into the line and that it was trapped. There is a cut off valve that's what I was working on. There are no leaks at that point but that is a good thing to test. Commented Jul 11, 2018 at 21:37
  • shut off all taps ... if you have a water meter, then check if it is showing water flow .... if you do not have a meter, shut off the main supply valve, wait 30 seconds or so, then turn back on a very small amount and listen for the sound of running water. (hissing sound) .... leave the main valve turned on just a small amount ... if the sound of running water does not stop, then you have a leak

    I suspect the answer is you’ve knocked loose scale and now need to clean the faucet aerators.
