Why Does My Pool Pump Lose Prime When Vacuuming?

When you’re trying to keep your pool clean and clear, vacuuming is an essential task that can’t be skipped. However, if you’re experiencing issues with your pool pump losing prime while vacuuming, it can be frustrating and confusing. Here are some reasons why this may be happening and how to solve the problem.

1. Air Leaks

If there are any air leaks in your pool pump system, it can cause a loss of prime. This can be caused by a cracked or loose pump lid or housing, or a damaged O-ring. To check for air leaks, turn off the pump and look for any visible damage. If you can’t find any, it’s possible that the leak is coming from the suction side of the system, which can be harder to detect. You may need to call in a professional to locate and fix the issue.

2. Clogged Skimmer Baskets

If your skimmer baskets are clogged with debris, it can limit the flow of water to the pump and cause it to lose prime. Make sure you regularly clean out your skimmer baskets to prevent this from happening. You can also try using a skimmer sock to catch smaller debris and prevent it from getting into the baskets.

3. Dirty Filter

A dirty or clogged filter can also restrict water flow and cause the pump to lose prime. Make sure you clean or replace your filter regularly to prevent this from happening. If you have a sand filter, you may need to backwash it to remove any trapped debris.

4. Wrong Vacuuming Technique

If you’re not vacuuming correctly, you could be causing the pump to lose prime. Make sure you’re using the right vacuum head for your pool type and size, and that you’re not moving the head too quickly. You should also make sure the vacuum hose is completely full of water before attaching it to the skimmer.

5. Pump Size

If your pool pump is too small for your pool, it may not be able to handle the suction required for vacuuming. You may need to upgrade to a larger pump to prevent it from losing prime.

Conclusion

If you’re experiencing issues with your pool pump losing prime while vacuuming, it’s important to identify and solve the problem as soon as possible. The above reasons are some of the most common causes of this issue, but there could be other factors at play. If you’re unsure or unable to fix the issue yourself, it’s best to call in a professional to ensure your pool stays clean and clear.
