The Webtrol Tank-E-Liminator is an airless water pressurizing system that has been used for the past 40 years.
As the name implies, the Webtrol Tank-E-Liminator takes the place of a conventional tank pressure system that requires air to operate. The Tank-E-Liminator is installed between two lengths of drop pipe inside the well casing, eliminating the need for any above ground storage tank. Its operation is simple. When the pump runs, an elastic member in the unit expands, providing a pressurized storage reservoir in the drop pipe. When water is used, the elastic member slowly contracts, providing draw off and preventing pump cycling.
The Webtrol Tank-E-Liminator is an ideal solution for those times when space is at a minimum or when the only location available to you to place a tank is where it would be subjected to freezing temperatures.
