    How to change filter cartridge w/out water loss?

    Hello, I have a question. I have an Intex pool 16x42 with a 2500 filter. Is there a way to change the filter cartridge without loosing water? I always seem to loose so much even when the pump is off. I know there are plunger valves but I can't find any reasonably priced ones at the moment. Thanks in advance

    This might not be any help but my Intex came with three of the stoppers for each hos . How long ago did you get yours?

    I got our pool last year. We may have gotten stoppers with it but I am not sure where they would be now. Can you buy new ones? I cut bigger holes in the pool for the new filter. If I find the old stoppers would they work? Thanks

    Old stoppers wouldn't work. A couple of tennis balls would. Downside is that you would have to unscrew the in-the-pool cover to use. just don't forget they are in there when you go to restart your pump.

    plug up the returns and drain...and then I would get some ball valves from home depot and install them while you have the system isolated. in the future you can just close the valves and clean the filter, then re-open. shouldn't take long to install some valves

    Lift the pump onto a chair or table above the water level before you unscrew the top. You'll never lose a drop.

    Some people have even used a potato they cut down to fit. That will work until you get the valves on!
