    Do you mind helping me identify my skimmer? I don't have a weir door and I'm pretty s

    My pool is older and I can only find the part number and a logo on the skimmer. It seems the skimmer would be a lot more effective with a weir door. Thank you!

    I think that you have a Pentair Admiral S20 skimmer. CMP makes aftermarket replacement parts. I suspect that the lid is a replacement.

    Pentair Admiral Skimmer Weir part number 85001500.

    95% sure.

    Also, I wouldn't plug the vacuum hose directly into the skimmer line. Debris can clog the pipe.

    If you have difficulty finding the exact one you can always measure the width and height and get a generic
    spring loaded one from amazon. Ended up having to go that route on my last pool. speaking of looks like
    your skimmer had a damaging freeze one time. (the missing plastic) Mine had that happen too, but lucky
    like yours the water level was way higher than the fill line when it happened. ouch.

    Thank you for the help on the skimmer. I don't see any name on the pool itself. It was installed in the 70s and I may be able to ask the prior owner. He's in his 90s but might remember who built it. I'll take some measurements and see if I can find a generic door to fit.

    What's the best option for the vacuum connection? A plate like this so my basket can remain in place? That would be easier than cleaning out the pump or potentially having to blast the line.



    I have an older Kreepy Krauly that works pretty well.

    The adaptor plate should work.

    I believe this is the American Vari-flo skimmer, to vacuum you will need this part , 85002600 | Vari-Flo Control Insert Only

    American was the original maker of the Admiral skimmer. Pentair acquired PacFab which previously acquired American, so now it's a Pentair product.

    The skimmer is Admiral. The adaptor is called variflo.

    How does the adaptor work?

    Note: Pentair acquired PacFab which had previously acquired Purex Pool Products and American Products.

    That's the adapter I have. It screws in to the fitting at the bottom of the skimmer and relies on the pump basket to catch everything. You can rotate the adapter to increase or decrease flow through the vacuum.

    As you mentioned James the debris traveling through the pipe intake can get clogged. That was the situation when I took over ownership of the pool and I had to blast it out with one of those hose bladders.

    Thank you so much everyone for the help in figuring out which skimmer I have. The pool business has had a lot of turnover.

    Re: Do you mind helping me identify my skimmer? I don't have a weir door and I'm pret

    I took some pictures inside the skimmer today because I can't feel any weir door mount pins. How does a weir door mount in a skimmer with no pins?

    On a side note I can see the plastic is starting to break down a bit so a skimmer replacement may be in my future. I'm going to guess the skimmer "ramp" isn't replaceable as a separate part.

    You can see why the weir door would be helpful. The arborvitae trees in my backyard drop a lot of junk. Once I have a VS pump I can hopefully run it on a low setting for skimming most of the day.

    Most of the skimmers I've seen have holes on either side near the bottom of the opening. The pins are on the door.

    I didn't feel anything but a smooth corner but I'll search a little more.

    I received my adapter plate and used it yesterday. The vacuum seems to work better than when it had a direct connection to the pump suction line and it's great not getting all that junk in my pump basket.
