Pump surging----low water?

[denno]

Greteings,
I live in a rural area, 2000' elev. Well is some hundreds of feet deep. No changes in equipment since we moved here 15 yrs ago.
Water supply has always been fine. Ran it dry a few times by leaving a hose on; always came right back.
This year we are well behind on rain. The water pressure surges with a cycle of maybe 10-20 seconds. Are these two observations linked?
If the one is causing the other, I have no concerns with it. We still have enough water. Wondering if it is indicative of any problem with the equipment, or any other cause other than low water.

Thanks,
denno

Surging usually means you are pumping the well dry. You are lucky it came back on after running dry even once. Sounds like you need to lower the pump or work on the well production. In the meantime one of these will save your pump.

Needed to replace the pressure balancing tank.

Needed to replace the pressure balancing tank.

The bladder in the pressure tank is just one of many things that is destroyed from cycling the pump on/off too much. The Bladder or diaphragm in the tank goes up and down with each pump on/off cycle until it breaks like bending a piece of wire back and forth. A bad pressure switch and/or a bad tank are just early signs of damage to everything from cycling.
