I've found the tutorials on variable speed pumps (I like, but the voltage spike issues worry me), and the information on filter types, sizing pumps & filters, and many other tutorials and threads that make me feel like I left the dark. Is there a sticky thread, or other area that compares "quality" of equipment? Two local companies have bid replacing my system, proposing a Waterway filter (and 2 different sized pumps), but I can't find much information on Waterway. I get the feeling filters quality doesn't vary that much, at least for me, as my equipment is inside a shed so weather is not an issue, but the lack of information bothers me. So the second question is, any experiences with Waterway filters out there? (325 or 425 sq.ft)
Given costs, and what I'm seeing -- <150 sq.ft. cartridge on a 20K + gallon pool, I'm going to replace the filter ASAP, and then figure out pump (motor or whole thing; 2 speed or variable) later in the summer, unless I get shouted down here . I may try the DIY route for economy sake, but I think the bigger decision is getting the filter choice right.
