On this project we were called in to find a solution to a water feature that was professionally built, but had gone totally wrong. The workmanship on this and surrounding projects were excellent, however the design of the water feature was flawed from the start. The bottom reservoir must be the largest, or it will, and was pumping dry. With about 14 feet of desired waterfall on the top, you would need a minimum of 14,000 gallons per hour of pumping water to maintain a decent flow of water. Our solution was 5 one foot wide waterfalls with built in led lighting to add night time interest. The customer was very happy with the results.
