    no. i've not done anything to it. my wife noticed that the hose was plump with water yesterday evening. i did a "mini" backwash this morning just to test functionality. seemed to bw fine and rinse fine, but noticed the difficulty in turning the valve and couldn't get it to stop leaking.

    i think there is a little white disc that is broken (where the handle rests on the valve itself). replaceable? i'd like to be able to get any parts i need on my way home tonight if possible.

    Not sure what a vari-flo valve is, but if it's like a traditional multiport valve, the valve itself may not be seating properly when you change positions. It is spring loaded and overtime the spring can get stiff. It may also be a worn gasket, spider or otherwise. The best thing to do is take apart and inspect.

    vari-flo is the name brand of the valve that sits on the outside of my filter with settings for filter, bw, rinse, waste, recirculate. i think that's all of em.

    Pierce,
    Welcome to the forum.
    Water leaking out the BW port indicates a damaged spider (or some call it a wagon wheel) gasket. Never had to disassemble the handle part of mine but I do see that white disk that they call a non-metallic bearing. For detailed info on this valve you can go to the Hayward website
    http://www.haywardnet.com
    as they have quite a few on-line diagrams, parts lists, and resources. As I stated it's the internal gasket that is damaged. Replacing this isn't hard and I think they run about $9 or so but I'm probably wrong about that. You'll need the model number of the valve because the gaskets are different. I have generated quite a bit of controversy on this forum about how to replace it. Some, including Hayward unless they changed, recommend crazy glue, others say no glue, I have my own way that has worked great for me for a couple years so far. I'll post details when and if the time comes.

    Couple more things Pierce. You can Edit your post instead of doing another post. Taking the valve body apart is easy. First, mark the position of the top and bottom halves so you are sure to align them properly when reassembling. Put the handle in a middle position, that is not in one of the detents, to relieve spring pressure. Remove the 6 bolts and nuts and pull the top half off. The gasket and internal guts will be obvious. When reassembling it is always good practice to snug the bolts lightly and tighten in a sequence where you don't stress any individual bolt. ex...if you number the bolts 1 -> 6 in one direction, tighten in the following order..1,4,2,5,6,3. Tighten a little at a time until you get them all tight. The tightness in the handle could be simply the O-rings on the handle shaft are dry. I never lubed mine in 9 seasons but probably would be a good idea. That's not your waste leak issue though.

    Default After inspection...

    at lunch i inspected the valve. as soon as i took the top half off i could tell that the "spider gasket" is the problem. there is one "spoke" that is badly stretched out and out of position and another that is stretched but not nearly as bad as the first.

    for the benefit of others on the forum i attached pix where you can see that the "spoke" on the left is arched. sorry for the quality of the photos....camera phone

    they have replacements for $7

    I've always been told to rotate the valve in one direction only. I've done that ever since mine was new, and have never had a problem with it. Mine's a clockwise valve! Really, I don't know if I'm just lucky, or whether it's a good idea.
