    picture of inside of sand filter?

    I've never had the top off of my sand filter. This is only the second season on fresh sand installed by the pool guy.

    If I want to remove the top and look inside how do I know if the sand level is correct? Is there a mark to show how high the sand level should be?

    What precautions do I take when I remove the top?

    What filter do you have? I have never seen a mark in one for sand level. Maybe you had a honest pool guy that didn't short you on the sand

    I'll bet you can find what you need to know if you google it.

    If you can find the manual for your filter, most of them are available on the Internet, it will say what the sand level is supposed to be. Typically it should be about 12" below the pipe that lets water into the top of the filter chamber, but that varies a bit.

    Before opening the filter you should have some silicone based pool/plumbers lube. The gasket that seals the filter should be lubricated before you re-assemble it.

    Generally they are fairly easy to take apart. Take it slow and be sure to notice where each part goes as you remove it.

    For safety reasons, make sure that you relieve the pressure in the tank befor you open it. On my filter there is a valve on top for bleeding the air out of the tank which I used to relieve the pressure.

    I'm guessing it never gets cold enough to winterize there? If it did, you would already have your answer since the multiport has to come off when winterizing. Always use care when adding, changing or manipulating the sand in your filter so that there is no damage done inside. Good luck.

    Perhaps you don't get a hard freeze where you are but here we freeze very solid. Any type of moisture in that multiport and hard freezing weather could mean disaster and damage. I guess it's not worth the risk that any ice, snow, rain could get in there and freeze/expand. We remove ours each year, then add a bit of bleach to the sand, drain again completely, cover the opening and filter tightly with a tarp, allowin the drain to remain open. The multiport is brought in for the season. It has lasted for many years as good as new this way.

    I live in central Massachusetts. We get below zero. I've never seen anyone take off the valve. Just drain the filter by taking off the plug at the bottom, remove the sight glass and the pressure gauge, and move the handle to the "winter" setting. Like I said, I've never seen anybody remove the whole valve. i really dont think it's necessary.

    Never seen anyone not remove it up our way. To each their own.

    On most sand filters, the sand goes up to the water breaker, which is a rim inside the filter that distributes the forced water into the chamber.
    The piccies here are of a filtrax model, but hopefully your model will have a similar guide. This particular model is side mounted.

    An empty sand filter looks a bit like this - but of course can vary from model to model.

    The sand line in the filtrax looks like this - you can see it in running the circumference of the filter.;

    When filling with sand, fill to just below the level is fine - do not go over it!! A freshly filled filter should look a bit like this;

    This is the filter in question;

    Precautions would include being careful of their weight - they weigh a ton. Ensure the chamber is no longer under any pressure. Be careful of the piping internally - after many years of service they can be brittle. Once the old sand has been scooped out by hand and the filter hosed out, position the filter back in its location then fill with new sand. Replace any O-Rings that were disturbed when accessing the unit - make sure you use plenty of silicon grease when preparing the O-Rings for sealing. Prepare the O-rings after the sand has been filled and the area dusted down of any sand.

    Hope this helps,

    Interesting. Never seen a side mounted filter before. The clear tubes made me think of the TARDIS (Doctor Who).

    Re: picture of inside of sand filter?

    Clear is very cool. I didnt realise how much fun it was going to be until it was done. I put clear piping in so the kids could see where the water was flowing as they always loved looking into the clear top of the pump filter basket. With the solar system, quite a few bubbles get into the line when pumping and they love it. Backwashing is a treat too.

    This is what it looked like before the covers went on. A shame really, since you can see them so much more easily without the covers in place.
