trying to save some money. I have looked up directions and the pool store guy who sold me the sand showed me the basics as well. My question, I think, has an obvious answer but had to ask. My Fox filter appears to be sitting on a stand, that may be built on or not, and I can't find a drain plug on the outside of the stand. So I assume the drain plug is underneath. So that appears to mean that I am going to have to loosen the filter from the pvc water lines so I can tilt the filter enough to get to the drain plug. Is it necessary to drain the water out from the plug or can I just use my shop vac to get the water and sand out? I hate to increase the trouble by having to pry the fittings loose on the pvc.
