For the bucket, you just need to drill a hole and mount a bulk head to drain the water. For the pipings, it's just 4 90 degree and a T and some fitting that connect to a tube. Really nothing to it. Oh, the most tricky part is just to cut the slot on the tube that hold the plastic screen. Since I can't re-use that part, you could have it for free. I did not even glue many of the pipings for the frame since water leaking is not an issue and I can always change out the pipes to change the height of thing.
Which part you want to buy? I suppose just the frame and the plastic canvas?
