Puretec SOL30-E1 Softrol water softening system requires less maintenance than semi-auto systems, after the initial installation simply set the times and dates requiring backwash and the unit regenerates automatically. These systems provide peace of mind water softening throughout the house. You’ll notice benefits all through the house. Soap and shampoos will lather better, your skin will not be as dry, and soap scum will be reduced. Clothes are softer and hot water appliances will last many more years. The E1-Matic valve backwash's automatically on a preset time, after the initial installation simply set the times and dates requiring backwash and the unit automatically regenerates. Power usage is extremely low similar to that of a garden watering system.
