Right and the hose was run. This reminds me of something. A few years ago the sump pump in our house was running non stop despite us not getting any abnormal rain fall. I called the county because I knew something was not right, I was thinking maybe there was a water main break or something affecting us. The county came out and took a water sample from our sump pump maintaining that chlorine would be found in the well if there was a leak. Anyway they took a sample and told us there was no chlorine found. Still not believing them I called a company that specializes in water testing. I was informed the ground/soil acts as a natural filter and the county wouldn't find any chlorine in our sump pump well because of what I stated above. Fast forward to a couple months later when outside of my house I noticed the sidewalk was wet(we had not had rain in a week) I called the county. They came out and dropped a tablet in the water on the sidewalk...low and behold the water turned RED which means chlorine was present. Indeed they had a water main leak in front of our house which was making my sump pump run NON STOP.
My point is I wonder what else the soil can filter out especially when a hose has been run or it rains. JMO.
