The line in the the joists is just a clear 1/4" line from a filter system run to my tank, My laundryroom pipes put out about 80PSI so i have valves on both ends of everything lol. My laundry room is kiddy korner to my tank so I had to go the whole length of the basement to get it there. I used to run a chlorimine/chlorine block and add water 24/7 on a drip to my tank as its got a bulkhead in the sump that goes right to the main drain in the house. I just use it as a back up now incase something goes more wrong than i though it could
it will atleast drain and not spill all over the floor.
