We need to move our StaRite Waterford Sand Filter System w/ JWP Pump (can't anything stay the same?!) due to a rebuild of our solar panel array. My husband wants to move it without removing any or all of the sand if we can get away with it. I'm afraid it may damage the spider gasket and entire housing as it's been in the sun/elements since 2006. Are they that delicate? Is it time to replace the sand anyway? Anyone have any experience? Thanks.
