Hello Everyone: I inherited (not by choice) a hydrospa 510 model spa. It is a late 2003 or early 2004 model. My problem is that I do not have the "Top End" to the filter housing. I believe it may be some type of skimmer but I have no idea as this is my first encounter with a spa. Most of the other components are marked as Waterway brand. Have looked all over the filter housing and can not find a part number anywhere, although I am proud to say that I identified the "Made in China" sticker. Filter # is 817-3501. It has some type of "locking" mechanism on the tub side of the housing. Any replies would be greatly appreciated and I can post more info if need be. Thanks again, Todd
