It's coming out slower than I would like, but I'm thrilled, none-the-less. I actually have a rock in front of the end of the tubing because the water literally sprays hard enough to shoot out over the pond and into the grass in front. The rocks on top would prevent that, but I'd be losing alot of water, so the small rock in front acts as a diverter and allows the water to flow better. Still can't figure out that leak though -- I have NO idea where it is even coming from. I have a pond liner under the spillway to (hopefully) collect and divert any leaked water back into the pond, but there was a decent amount of water flowing on the rocks before this liner and I'm not seeing any of it now -- which leads me to believe it's found a different path to the ground and not into my pond.
Thanks for the compliments on the rock wall! I had the downspout and extension to cover, as well as the electrical, so it needed to be high, and I wanted to extend it over to the higher ground to make a nicer transition. It turned out better than I had hoped!
One question: the tubing and electrical cord running from the pump prevent me from placing the pump in the middle of the pond. As a result, it lies about 1 foot out from the waterfall. Will that create enough water turnover for the pond?
