why does a pool pump lose prime

Author: Poolking - Swimming Pool Equipment Manufacturer

There is nothing more frustrating than losing prime in your pool pump. Not only does it stop your pool from being clean and healthy, it can also cause damage to your pump if left unchecked. But why does this happen? In this article, we will explore the top reasons why a pool pump loses prime and what you can do to fix it.

1. Air leaks

One of the most common reasons for a pool pump losing prime is due to air leaks. These leaks can occur in a number of places, such as the pump lid, the suction lines or the skimmer basket. When air enters the system, it displaces water and stops the pump from working efficiently. To check if there is an air leak, turn off your pump and check all the fittings and connections. If you notice any air bubbles, this is a sign that air is entering the system.

2. Clogged skimmer basket

Another common culprit for losing prime is a clogged skimmer basket. When the basket is blocked, the flow of water is reduced, which in turn affects the operation of the pump. Always make sure to clean your skimmer basket regularly to avoid any blockages.

3. Blocked impeller

The impeller is an essential component of the pool pump, responsible for drawing water through the circulation system. When the impeller becomes blocked with debris, it can no longer spin effectively and loses prime. To fix this issue, turn off your pump and remove the pump housing cover. Check the impeller for any blockages and clean as necessary.

4. Low water level

If the water level in your pool falls too low, the pool pump may not be able to function correctly. This is because the pump relies on a consistent water level to draw water through the system. Always ensure that your pool water level is high enough to keep the pump functioning.

5. Faulty pump

Lastly, if none of the above issues are identified, there may be a more significant problem with your pump. This could be due to a worn-out seal or a problem with the motor. In this case, it's important to contact a pool technician to diagnose and fix the issue.

In conclusion, losing prime in your pool pump can be frustrating, but it's essential to address the issue as quickly as possible to avoid further damage. By understanding the common causes of losing prime, you can take steps to avoid them and keep your pool running smoothly. Always remember to regularly clean your pool skimmer basket, check for air leaks, ensure the water level is adequate, and remove any blockages from the impeller. If all else fails, contact a professional pool technician to diagnose and fix any underlying issues.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
