I have gone to 3 places in the past week where the water was off or the pressure was down.
It took me 20 minutes to figure it out the first time because I’m an idiot the pressure would build up when I had the sprinks off but when I turned them on they would start out fine then act like there was a plugged line. When I turned on the hosebib, it seemed like there was normal pressure. Looks can be deceiving, Grasshopper. Now I hook up my pressure gauge if things aren’t working normally.
The people in charge of the water in each neighborhood will turn on the water to flush out the lines and test the system. This is a normal practice. Sometimes they turn on the water and then turn it off to clean out the filters and fix leaks. This will lead homeowners to believe that “The water is on, Hallelujah!”.
I’ve done turn-ons and adjusted everything perfectly and then the homeowner will give me a call in a couple of days and say it’s not working properly. I’ll go back and it’s working again. I have learned to tell them to wait a couple of days and then call me back if it’s still not working.
