Pool pumps are the lifeblood of any swimming pool. They keep the water circulating and ensure that your pool stays clean and healthy. However, sometimes, these pumps will not prime. This can be frustrating for any pool owner, especially if you’re trying to enjoy a swim on a hot summer day. In this article, we’ll explore what causes a pool pump not to prime and how to fix it.
What Does it Mean to Prime a Pool Pump?
Before we dive into the reasons why your pool pump may not be priming, let’s talk about what it means to prime a pool pump. Priming is the process of removing all the air from the pump and filling it with water. Pool pumps are designed to work with water, and if there is air in the system, it will prevent the pump from working correctly. When a pump is not primed, it cannot create the suction necessary to circulate water through the pool system.
Reasons Why Your Pool Pump May Not Be Priming
1. A Clogged Skimmer or Pump Basket
One of the most common reasons why a pool pump will not prime is because the skimmer or pump basket is clogged. When debris accumulates in the skimmer or basket, it can stop water from flowing into the pump, which prevents the prime. Make sure to keep your skimmer and basket clean to avoid these issues.
2. Low Water Level
Another common cause of a pool pump not priming is due to low water levels. If the water level in your pool is too low, the pump will not be able to draw in water efficiently, causing it not to prime. Ensure your pool water level is always up to par.
3. Air Leaks
If there is air leaking into your pool system, it can prevent the pump from priming correctly. Check for leaks in the pump lid, valves, and pipe fittings. Sealing these leaks should solve the problem.
4. A Worn Out Pump Impeller
If your pump impeller is worn out, it will not be able to create the necessary suction to start the prime. Over time, impellers can wear out, especially if there is debris in your pool system. You may need to replace your impeller if this is the issue.
5. Wrong Pump Rotation
Lastly, if your pump is rotating in the wrong direction, it may cause the pump not to prime. A pool pump should always rotate counterclockwise when viewing it from the motor end. This rotation will help with the efficiency of the pump prime.
How to Fix a Pool Pump That Won’t Prime
If you’ve determined that the problem is, in fact, a pool pump not priming, it’s time to find a solution.
1. Check the Skimmer or Pump Basket
The first step is to check for any clogging in the skimmer or pump basket. Remove any debris or large objects that are obstructing the flow of water.
2. Check the Pool Water Level
Another solution is to check your pool water level. If the level is too low, fill the pool with fresh water. After refilling, turn on the pump and see if it starts to prime.
3. Check for Air Leaks
If the problem persists, check for air leaks. Look for loose fittings, cracked lines or broken valves. Tighten and secure any loose points with sealant or replace broken parts.
4. Check for a Worn Out Impeller
If your impeller is worn out, replace it. You can do this by removing the pump housing and replacing the impeller with a new one.
5. Check the Pump Rotation
Lastly, check to see if your pump is rotating in the correct direction. If the pump is rotating in the wrong direction, you’ll need to reverse its rotation.
A pool pump not priming can be frustrating, but it’s essential to rectify the issue to maintain pool health. By following these solutions, you should have your pool pump priming in no time!.
