    Water tank - what's the right tool?

    I'd like to clean out a water tank or two, and the inspection cover on top of each tank is a plastic (and probably brittle) cap with four small lugs around the perimeter.

    Somewhat like this:

    It is... uh... resisting attempts to get it to move.

    Although it's tempting to put a delrin rod against one of the lugs and tap it until it turns, there's got to be a better way.

    What's the right tool to use here, in order to get the thing open without breaking off any lugs?

    I would suggest using a strap wrench on the cap, along with gentle heating with a heat gun on the threads.

    No joy. The tank cap itself is accessed through an 8" inspection port. No way to get a strap wrench down onto the same plane as the lid, I need something I can apply from above.

    Something like a 3 leg wrench may work if you can find one large enough and can get it tight enough.

    That's a very cool tool. Is the cap too large for a basin wrench?

    Probably. I haven't measured but I'm going to guess it's 3-1/2" in diameter (plus the lugs)

    Current thinking is that I can craft a 2-leg version of the 3-leg tool, using a length of scrap metal and a couple of appropriately-spaced hex-heads.

    Turns out one of these worked just great.
