    Pool Water Level with Hayward Auto Skimmer?

    We are in the middle of building an 36' x 18' Inground Vinyl Pool. The concrete pool coping was poured today and I noticed that the skimmer box was riding pretty low in the pool. When I measured the distance from top of concrete to the top of the skimmer inlet, it measured 8.5". The skimmer is a Hayward Auto-Skim series - here is the link to the manual, not sure which model but it is the wide mouth version - https://www.hayward-pool.com/pdf/man...P1084-1085.pdf Doesn't there need to be an air gap to allow leaves/bugs/debris to enter the skimmer? Does this mean that the water level is going to be ~9" below the top of concrete?

    The water level should come about halfway up the skimmer mouth for best operation. See the diagram on the fourth page of your link. That is rather thick for coping. More pictures in context would be helpful.

    Additional Information:
    Coping is 4" thick, the 8" board is just holding the Rock Cut mold in place.
    Also installing an Automatic cover which is probably why the skimmer is so low.

    Your water level is going to be about 11" below the top of the form if the top of the form is actually the top of the deck. My coping is about 1-1/2 inches thick so my water level is about 5 inches below the deck level. That sure does not look correct but I am not a pool builder. Any chance you could post a wider shot and a shot of the top of the form?

    Re: Pool Water Level with Hayward Auto Skimmer?

    If no one else gets back to you tonight, in the morning I'll go measure the distance from the top of my coping to the middle of the skimmer and another measurement from the bottom of the coping to mid-skimmer. 11" seems excessive to me but the picture of the measuring tape held against the wood form is confusing: does the coping itself go as high as the wood form or is it some where below?

    Re: Pool Water Level with Hayward Auto Skimmer?

    Thanks for your help. The top of the wood framing is the top of the coping. Hope this following picture helps clarify. Forms come off this morning, so I will update the photo without the forms, which should also help clarify. However, I do believe ComputerGuyInNOLA is right, the normal operating level in the pool will be ~ 11" below the top of coping
