We discovered we have a leak because the carpeting became wet and discolored, while spreading. Pulling back the carpet, the padding was wet and the tacking strip to hold down the carpet was dark and saturated. Pulling back the floor board, we discovered a 12 inch area also dark and wet. We have a problem, but we don't know how to find the source. Could it be coming from a window on 2nd floor, but not directly above? (there is NO window directly above)
No sprinkler system. We use soaker hose and it is on a timer (conservative water users). We live in a DRY, arid state, and we don't plant close to house.
