Don't Let Your Pool Pump Lose Prime! Your Guide to Preventing Costly Headaches in Las Cruces
Is your pool pump losing prime? Nothing is more frustrating for a pool owner than a pump that just can't seem to get its prime back. You hear it running, but the water flow is weak or non-existent. This common issue, often related to a leak or air entering the system, can quickly lead to bigger problems and higher utility bills. Here at Otter Desert Pools, your local pool leak detection experts in Las Cruces, we understand the stress this can cause. We’re here to help you understand why your pump loses prime and how to fix it, preventing your pump from losing prime in the future.
What Does it Mean When Your Pump Loses Prime? And Why Does It Matter?
When your pool pump loses prime, it means it’s no longer effectively moving water. A pump works by creating suction to draw water from the pool, pushing it through the filter, and then back into the pool. To do this, the pump housing needs to be completely filled with water. If air enters the pump casing, it can’t create the necessary suction, causing the pump to lose its ability to move water. This isn't just an inconvenience; a pump running dry can overheat and suffer significant damage, leading to expensive pump repair or even needing a new pump.

Why Does My Pool Pump Lose Prime So Easily? Common Causes Explained
There are several common causes for a pump to lose prime. Understanding these will help you troubleshoot and prevent future issues. The most frequent culprits involve air entering the pump or the suction side of the system.
1. Is There an Air Leak in Your Suction Line?
This is perhaps the most frequent reason a pump loses prime. An air leak on the suction side of the pump allows air to be drawn into the system instead of water. This could be due to a loose connection, a crack in the suction line, or even a faulty valve. If your pump is losing its prime frequently, especially after you've worked on the plumbing, an air leak is a prime suspect. Otter Desert Pools specializes in finding these elusive leaks, ensuring your pump can maintain prime.
2. Is Your Water Level Too Low in the Pool?
Sometimes the simplest answer is the correct one. If the water level in your pool drops below the skimmer opening, the pump intake will start sucking air instead of water. This will inevitably cause the pump to lose prime. Always ensure your water level is at least halfway up the skimmer opening.
3. Is Your Skimmer Weir Stuck or Blocked?
The skimmer weir is the small, hinged flap in your skimmer basket opening. If it gets stuck in an upright position or is blocked by debris, it can restrict water flow into the skimmer, leading to a loss of prime. Always check for leaves or other debris that might be causing a blockage.
4. Is the Pump Lid or O-ring Damaged?
The clear lid on top of your pump (where you empty the basket) has an O-ring that creates an airtight seal. If this O-ring is dry, cracked, or if the pump lid itself is damaged or not tightened properly, air can easily enter the pump housing, causing the pump to lose prime. Always lubricate the O-ring regularly and ensure the lid is securely fastened.
5. Could a Faulty Check Valve or Foot Valve Be the Culprit?
A check valve or foot valve prevents water to drain back into the pool or well when the pump is off. If either of these valves is not sealing properly, water can drain out of the pump casing, allowing air to enter. This means the pump will struggle to draw water and lose prime whenever it starts up. If you have a well pump, a malfunctioning foot valve can be a critical issue. You might need to replace the check valve.

How Do You Fill the Pump and Re-Prime It?
When your pump loses its prime, the first step is always to prime the pump again. Here’s a basic guide:
- Shut off the pump: Safety first! Turn off the power to your pump.
- Release Air: Locate the air relief valve on your filter and open it to release any trapped air.
- Fill the Pump Casing: Remove the pump lid and fill the pump housing completely with water using a hose. Fill until the water in the pump is overflowing.
- Replace and Secure: Put the pump lid back on, making sure the O-ring is clean and lubricated, and tighten it securely.
- Turn On the Pump: Turn the power back on. The pump should now be able to catch its prime. If not, repeat the process.
If you have to prime the pump repeatedly, it indicates an underlying issue that needs to be addressed.
Troubleshooting: Finding That Pesky Leak That Causes Your Pump to Lose Prime
If re-priming your pump is a constant task, it's time to play detective. Otter Desert Pools are the local experts at pinpointing leaks, but here are some steps you can take:
- Inspect the Suction Side: Carefully check all connections, pipes, and fittings on the suction line (from the skimmer to the pump). Look for drips, cracks, or loose fittings.
- Listen for Air: When the pump is running, listen closely around the pump and suction pipe for a sucking or whistling sound, which indicates air entering the system.
- Soapy Water Test: Mix some soapy water in a spray bottle. Spray it on suspected air leak areas (fittings, pump lid, valve stems). If you see bubbles forming, you've found an air leak.

Preventing Your Pump from Losing Prime: Proactive Steps
Prevention is always better than cure! Here’s how you can prevent the pump from losing prime:
- Maintain Water Level: Regularly check and maintain your pool's water level.
- Inspect and Lubricate O-rings: Periodically inspect and lubricate the O-ring on your pump lid and any other O-rings or gaskets in your pump system.
- Check Skimmer and Pump Baskets: Keep skimmer and pump baskets free of debris to ensure unrestricted water flow to the pump.
- Regular Leak Checks: Consider routine professional leak detection, especially if you have older plumbing or suspect a hidden issue. Otter Desert Pools can perform thorough checks for your irrigation system or pool to ensure no small leak is causing your pump to lose prime.
