Hello people.

I am planning on building a canvas tank with a dimension of 8ft(L)x4ft(W)x3ft(H) and keeping the water level at 1.5ft with an overflow into a sump tank.

I saw a DIY overflow pipe using pvc on youtube but I'm not sure if it will work as the height of the tank rim exceeds the water line by at least 1.5ft.

Any advice on how to plumb it without making any holes into the canvas?
