I know I need to drain some water off. I have a cartridge filter on the pump and wondering if I could use that somehow to drain about 2 inches of water. The first time I lowered level, I just unscrewed the pipe to return jet... It worked but was a big mess. I do not have a hose bib attachment. Thought about using the cartridge drain plug, but wouldn't that just drain water from the cartridge casing? And if I did, and pump on wouldn't that cause damage? The store I got the pool from had in starter package what looked like a roll of blue tape, but I found out this is for sand filters, and its no big enough to fit on pipe couplings. Any suggestions before I have to invest in a pump? Thanks
