    side vs top mount

    Looking at replacing old sand filter.

    Any reason to choose of top mount over a side mount (or vice versa)?
    Thanks

    Re: side vs top mount

    The first thing I would ask is why are you replacing it?

    Side vs top mount isn't really an issue. Either works fine and there's really no downside to either. Large filters usually come with side mount valves just due to the height that a top mount would wind up at.

    Re: side vs top mount

    Reasoning, the lid keeps blowing off and it is old and now the plastic bleeder value is cracked at the lid . Also the multiport leaks, even after I replaced the spider gasket last year. It just doesn't seem to be worth trying to fix anymore.

    Thanks for the reply.

    I have found two source that list the side mount version at about $200 more expensive than the equivalent top mount. I am not sure why the drastic price difference, as you suggest, they seem to work exactly the same. I am going to have to do some replumbing regardless (probably moreso with the top mount), but for a $200 savings , I do not mind the extra work.

    Re: side vs top mount

    If you talking Sand filters there are some advantages (atleast to me ).....

    With a side mount you dont have to cut your plumbing if you need to change, or unchannel your sand. Also if a lateral cracks..etc....

    On a top mount unless you have unions plumbed in and have to do the above you are replumbing.

    Re: side vs top mount

    Good point there. Had not noticed how the top mount makes access to the internals more complicated. . That is a definite minus, thanks.

    Re: side vs top mount

    To me, the top mount is actually better for getting to the internals. On a side mount you have to mess with those bulkhead fittings.

    A side mount also has to have unions, it's just that they're already there. On a top mount you just have to add a couple. Six of one, half dozen of the other kind of thing I guess.

    Re: side vs top mount

    Dave,

    Is there a photo somewhere of your setup? Also does the lid screw on or clamp on? My current lid screws on, and it seems that the fiberglass hole is more oval than circular (I am not sure if that is possible, it just seems that way) which probably is helping the lid fly off in my case.

    Thanks as always.

    Go with top mount and put in unions.

    I don't recall posting a photo. It clamps on with a split clamp assembly.

    Re: side vs top mount

    I've had both in the past and I prefer the side mount now...makes it very simple to inspect/hose backwash your sand a lot easier if needed..but as stated above...personal preferance.

    Re: side vs top mount

    I installed a top mount when I first built my pool but now wish I had installed a side mount. The configuration of my equipment behind my pool house would have made my plumbing simpler as I had to use a lot more elbows to get the plumbing routed correctly.
