The WaterMatic family combines the best features of Ritchie waters, with the easiest operation and simple maintenance. The WaterMatic 100 is a small compact design, is fully insulated to keep the water cool in the summer and provide added protection during the winter. The drop in cover is easy to lift for maintenance and cleaning. Trough slopes towards drain hole for easy cleaning and debris removal. Drain plugs can be moved to the valve chamber opening for short-term trough shut-off, during cleaning, when the pen is empty or during excessively cold nights. Low capacity and fast refill valve allows for low water waste and fresh water on demand. Optional heat package is required in freezing conditions.
