What causes a pool pump to start surging?
That is, when the water flows into the pump intermittently; it starts to catch prime, and then loses it, and then catches again. Surging pool pumps also make a tell-tale noise as the water level in the pump rises and falls. What is it that cause pump surge? Read on… Yes, the number one cause of water surging in the pump is a classic air leak.
Why is there air coming out of my pool pump?
Next, if your filter has a bleeder valve (usually at the top of the filter) open this while the filter and pump are running until water spits out of the valve and then close immediately. This keeps air out of the tank and allows for maximum efficiency of filtration.
What happens when a water pump is stopped?
If the pumps are suddenly stopped due to a power failure, the kinetic energy of the water combined with the low inertia of the pump may cause a separation in the water column at the pump or at a highpoint in the pipeline. When the columns of water return via the static head of the line, the reverse velocity can exceed the normal velocity.
When does a pump need to stop to cause a surge?
For the earlier example of the 12-in line, the critical period would be as follows for a 4-mi long steel pipeline: To cause surges, a pump does not need to stop quickly nor does the valve need to close instantaneously (or even suddenly). A normal flow stoppage of 5 or 10 seconds may cause the maximum surge in long pumping systems.
That is, when the water flows into the pump intermittently; it starts to catch prime, and then loses it, and then catches again.

Why does my water surge when I run out of air?
The tank needs air to compress for pressure. Without enough air, the tank becomes water logged causing water pressure to surge Bladder pressure tank- The air and water are separated which eliminates water absorbing the air. If the bladder becomes ruptured or torn due to fatigue surging will occur.
Why does my well pump keep surging water?
If the precharge is out of adjustment with the pressure switch surging could occur. The Nipple or Pressure Switch could be plugged with corrosion, not allowing the switch to monitor pressure properly. Production of pump is more than the well produces
