We're thinking about adding a waterfall to our existing pool. My main concern is having to break away all the existing pavers and digging and drilling a to run a new intake pipe for the pump. All the vibration from the jack hammer could crack the plastic since I have a very narrow clearance to work with. So what if I used clear PVC pipes and run it down the side of the pool behind the waterfall a few feet down then use a self priming pump. Would this idea work? It'll be a relatively small, the whole aquascape will probably be 4-5ft wide, 3ft deep and 3-4ft high.
