Description

Waterra Surge Blocks are excellent well development, surging and cleaning tools developed to work with the Waterra Pump System.

Surge Blocks are plastic rings or donuts that simply press fits over the body of either a Standard Flow D-25 Footvalve, or a High Flow D-32 Footvalve.
The surge block effectively increases the outside diameter of the Footvalve reducing the annular gap between the valve and the inside of the well screen resulting in a significant increase in the surging action of the Footvalve – Surge Block combo. As the combo moves up and down in the well, fines drawn into the well or stirred up will be pumped out through the Footvalve and removed from the well.
