My home is on a well and I have noticed a "runoff" going down my driveway even when there has been no rain during the day. I live on the side of a hill and I live in Oregon (where it rains alot). How can I determine if I possibly have a burried pipe leaking or just runoff from my hill?
Try to see if your well pump is running even though your not using any water. If it is you may have a split in a pipe. Another way would be to have your well man chlorinate your well and then test your runoff to see if the water contains chlorine.
Another possibility is to shut off your well pump for a day. Do this in dry weather on a day when you won't need water in the house for a day. Then 1) shut off the breaker to the well pump. 2) Release any pressure by turning on a faucet until all pressure is gone. If the "leak" continues at the same level after all day, it's not likely to be a leak in your system.
