I recently remodeled a spa and used 12×18" pieces of travertine that over hang to create a waterfall. The problem is I do not have enough water flow to create a "sheet". I know I can replace the pump or direct more water to the spa but the is not an option. Can I make any special cut or create a somewhat steep angle on the spill way? It has a small slope towards the pool but the water still trickles off the rock and runs on the bottom of the travertine and down the front of the spa.
Any suggestions???? Please help
