OOOOOOOOHHHHHHHHHHHHHHH lol i was gettin a little worried there LOLClay pellets that look like deer ****. Just didn't want to redo my drawing. Sump is filled with Siporax and filter socks before with a large fluidized sand filter. Just wondering about the plumbing and if the flange is necessaet or a better idea to keep pipe upright. Wanted the drain on the bottom instead of an end cap so no dead zone ..
