    What is this?

    We have a late 70's fiberglass pool and I'm trying to identify this metal tube in the deck. You can see it at the top of first picture below. Its located about 7' from the skimmer and descends at an angle towards the deep end of the pool. I have removed the cap and there isn't any water in it (at least in the first couple feet)

    Here is a close up

    We are planning a remodel of the pool area and wanted to know what it was so we can plan accordingly. Thanks
    Thanks,

    Looks like a deck jet.

    It might go to a well point to lower the water table if the pool needs to be drained.

    It might be a line for a fountain.

    If you know the builder, they might know.

    Re: What is this?

    Does your pool have main drain?
    If so, maybe the line for a hydrostatic valve? (if so this is sort of strange way to do it, but we've seen stranger).

    Yes Dave there is a main drain which is connected to the skimmer. I can adjust a valve in the skimmer to include or exclude the main drain. Is there a way to test your idea?

    Re: What is this?

    Im not sure if there is or not Staudi. Im not terribly familiar with hydrostatic valves or if they can be tested from deck side.

    There are other folks here who know much more than I do about them. Perhaps they will chime in soon enough.

    Hydrostatic valves are usually threaded into a hole in the bottom of the main drain. It would not be plumbed up into the deck like that.

    I think that it most likely goes to a well point under the deep end.

    I agree, my pool has the same thing, there is a fitting in the retaining wall below the pool that you can pump the water from below the deep end if you need to drain the pool.

    Re: What is this?

    The well point for my fiberglass pool is much larger than this one. In fact, the lid is the same size as a skimmer basket lid (or *is* one) and within that is PVC pipe of the same diameter. I see rocks down at the bottom, and it would be big enough to drop a sump pump into if ever the need.
