WebRishabh Bajaj posted a video on LinkedIn WebIf your well has started producing less water, turn to Saratoga Water Well & Pump Co. for effective hydrofracturing. Low water production can be caused by low rainfall or other factors. We use 6,000 gallons of potable water to flush out mineral build-up and sediment in your well's veins and will create new veins by pumping water down the well at 3,000 psi.
