The easiest way and it might be the same as ponds is the have the water flow into a tub that overflows to make a waterfall. It is better than trying to direct water from a jet or jets or a waterfall fitting. The bigger pre fab pool waterfalls use this method. Remember to install a valve to regulate pressure since most pool pumps are 40+ GPM That's a good idea on the valve. I have a 3/4HP Sta-Rite pump that I plan to use for the waterfall. I've been scouring the internet on the DIY waterfall idea. I have seen a lot on the pre-cast stuff but very little on using real rock. I did find a small Youtube clip on natural stone installation but it didn't get into detail on how the seal it to keep it from leaking. Thanks for the help. v/r Neil

I'm in the process of building an inground vinyl liner pool and would like to include a waterfall feature. I am planning to drystack some rather large rocks with some good sized flat rocks for the waterfall portion of the feature. I am trying to figure out what the professionals use to keep the water from leaking as well as keeping the water flowing in the right direction. I have built waterfalls for Koi ponds before using rocks and black liner to keep the water in check but I'm not sure if the same type of installation would be correct for my pool. Any help is appreciated. Thanks Neil
