Description
The Series WTX tanks will help protect the pump and pressure switches against short cycling. The potable well
tank delivers adequate water under pressure between pump cycles to meet the required demand. It will provide
economical system operation by minimizing pump starts, extending pump motor life, and saving energy. The
WTX tank will also assist the pump in meeting peak demands.
