I have a customer who is going to install an in ground pool, but is unsure whether to go witha poured in ground, a constructed in ground similar to an above ground, made to be installed in ground, or a fiberglass insert in ground. He would really like to avoid a fence, so is looking at the powered pool covers to avoid the town ordinances that call for a fence.... The real challange comes now...because he wants a water fall to drop into the pool. He really likes the Rosetta Stone water fall look, but I am unsure how to work this with a pool cover... Do any of you brilliant fellas have any suggestions for my problem? Thanks a bunch!
