no not here either, I am not going to poke holes in my walls or floor and all the rest, maybe 5 years down the line when all 7 kids moved out and sell this place and buy a smaller perm house for me and the wife to retire in.
I use the trash can on wheels-method, empty it w/ 5g buckets into the wash basin and refill with a hose hooked up to the wash basin sink. For smaller tanks I'll use a few buckets and just do it all manually
