Hello everyone. I am wanting to build a water fall for an inground pool. Something along the lines of fake rocks built from a styrofoam type material, so it can be removed and stored in the winter time. I was wondering if anyone here had any experience with this type of project. Also the pool builder is going to plumb and wire for this future water fall. What type of enclosures are there that can be placed into the concrete so I can access the plumbing and electrical when the water fall is installed.
