I'm in the process of remodeling my pool, and am considering adding a small wall on the edge of the pool with a water feature. There's an abandoned return line system that I can tap into for water, but the problem is the lines are only 3/4", which I don't think will be able to provide enough flow for most water features (and likely the reason it was abandoned). In the past I've used DIY aerators hooked up to the main returns to cool the water in the summer (and drop the TA), and the kids really loved playing under the streams of water. I'd like to have something similar, but easier to use and nicer looking.
I've been playing with cinder blocks trying to decide on the size/shape of the wall, and have attached a pic showing the rough idea of what we're considering.
Any thoughts or suggestions?
