After owning our pool now for a couple of years, I am starting to wish we would have done some type of rock water feature during construction. We definitely have all the room we would ever need but at the time we just didn't have the budget. In online research I've ran across some of the artificial rock waterfall features and were wondering if anyone has any experience. The picutres look pretty close to real rock but I have to assume at a fraction of the cost. I assume plumbing wouldn't be to involved other than changing out the 2 way return valve i have for a 3 way valve. Any thoughts, experiences and especially pictures would be definitely welcome! Thanks in advance!!
