I've decided to plumb my 240g into my house's plumbing for draining and filling the tank. Luckily there is a bathroom just on the other side of the wall from where I'm setting things up. I have two 40g breeders that will be connected via dual siphon tubes for a sump. Very much like fmueller's setup. Ideally I'd like to divert off of one of the return pumps into the drain pipe from the bathroom sink for quick water drain. I'd also like to connect the hot and cold water lines to some kind of dual-valve or hydrostatic mixing valve setup right over the sump for quick filling. I'm no plumber nor much of a DIY guy, so does anyone have any guidance/tips/warnings for me?
