Mine is in a cabinet above my washer in my laundry room. It provides a supply, drain, and now worries in case I had a leak. I forgot to turn it off one day, and found out that my laundry room has a drain built in to drain any access water outside of the house into the yard. I'm at work, so I can't upload any photos, but, here is what I had. From another thread...

I have now taken the output line, and run it through my attic to my fish closet (right behind my tank and plumbed into my sump via a separate mixing tank) on the other side of my house with NO booster pump. It has a goes upward about 8 feet, then about 180 feet through the attic, and down another 8 feet to my mixing tank. These units can push more than we may think they can. I did, notice that it does, however take an additional hour to make 35 gallons of water, though. Small price to pay for not lugging 35 gallons of water across my wood floors...
I'll post more pics tonight if you are interested...
Oh yeah: With it in the laundry room, the temperature is also very closely matched to the temp of the tank.
