Hi All, I have a leaking pipe, which we have traced to the pool area. The weird thing is, the pipe originates from our water main in the basement shortly after the master shut-off valve. This pipe heads through the side of our house, out of the brick wall to the pool-pump area, then dives down into the cement! I have no idea where it goes. There is a ball-valve near its origination from the water main, and also a ball-valve as it exits the side of our house. Here are a few pics of it back in the corner.
I don't know much about pools, and the company that built it is out of business. The pool has a separate auto-fill which is connected to a hose which comes out of a hose-outlet. We do have an auto self-cleaning system built into the pool -- do these ever take fresh water from the water main? There are a few water features that dump back into the pool. One thing I have noticed, is that although the auto-filling hose has been shut off the past 4 months, the water level has increased about an inch. Given the relative lack of water over the past 4 months, I would have expected the level to have dropped a little. (well, this could be totally unrelated). But, our water bill has been $300/mo, and with no wet spots or internal leaks... when we shut off the valve to this pipe, the leak-meter stops cold.
Anyone have any idea what such a pipe might be for??! Anyone have a similar pipe from their water main to their pool system?? I am hoping I can leave it shut off forever, but fear it is somehow integral to our pool's functioning.
