Why is My Pool Pump Surging? Troubleshooting Common Causes and Solutions

If you’re a pool owner, you may have encountered a situation where your pool pump starts surging unexpectedly. This can be frustrating and puzzling, but understanding the reasons behind this issue can help you troubleshoot and resolve it effectively. Surging pool pumps can be caused by various factors, including improper installation, clogged filters, air leaks, or a malfunctioning pump motor. By addressing these issues promptly, you can ensure that your pool pump runs smoothly and keeps your pool water properly circulated and filtered.

Improper Installation

In some cases, pool pump surging occurs due to improper installation. This could include issues such as incorrect pipe sizing, improper voltage supply, or inadequate wiring. If the pump is not properly installed, it can struggle to draw water efficiently, leading to surging. To resolve this, it’s essential to enlist the help of a professional pool technician who can assess the installation and make any necessary adjustments or repairs.

Clogged Filters

Clogged filters are another common culprit behind pool pump surging. When the filters become clogged with debris, such as leaves, twigs, or other particles, it restricts the flow of water into the pump, causing it to surge. Regular cleaning and maintenance of your pool filters are crucial to prevent this issue. Make it a routine to clean or backwash your filters according to the manufacturer’s guidelines to ensure uninterrupted water flow and prevent surging.

Air Leaks

Another potential cause of pool pump surging is the presence of air leaks in the system. Leaks can occur in various places, including the pump lid, strainer basket cover, or any pipe connections. When air enters the system, it disrupts the pump’s ability to create a consistent flow, resulting in surging. Inspect all the connections, gaskets, and o-rings for any signs of wear, damage, or looseness. Correcting these air leaks by tightening fittings or replacing damaged components can help resolve the surging issue.

Malfunctioning Pump Motor

If you’ve ruled out issues with installation, clogged filters, and air leaks, a malfunctioning pump motor could be the reason behind the surging. Over time, pump motors can degrade, resulting in erratic performance and surging. If you suspect a faulty motor, have it checked by a professional technician who can assess its condition and determine whether repair or replacement is necessary.

Inadequate Water Level

One often overlooked factor that can cause pool pump surging is an inadequate water level in the pool. When the water level is too low, the pump can draw in air instead of water, leading to surging. Ensure that your pool’s water level is maintained within the recommended range to avoid this issue. If the water level drops significantly, it may be due to a leak in the pool or excessive evaporation, which should be investigated and addressed promptly.

Summary: Keeping Your Pool Pump Operating Smoothly

A surging pool pump can disrupt the balance and cleanliness of your swimming pool. By understanding the potential causes behind this issue and taking appropriate action, you can keep your pool pump operating smoothly. Regular maintenance, including cleaning and inspecting filters, checking for air leaks, and ensuring proper water levels, is essential. Seeking professional help when needed for installation or motor-related issues can also play a crucial role in maintaining your pool pump’s optimal performance. With proper care and attention, you can enjoy a consistently functioning pool pump and a sparkling clean swimming pool all season long.
