A swimming pool is a great addition to any home, providing a place to relax, exercise, and entertain guests. However, owning a pool also comes with responsibilities, and one of the most important is maintaining the pool pump. The pool pump is responsible for circulating the water in the pool, which helps keep the water clean, clear, and safe to swim in.
One common problem that pool owners may encounter is when the pool pump won’t prime. In this article, we will explore the causes of a pool pump not priming, how to diagnose the problem, and solutions to fix the problem.
We will also discuss preventative measures to keep your pool pump in good working condition, as well as when to call a professional for help.
Causes of a Pool Pump Not Priming
There are several reasons why a pool pump may not prime, and understanding the cause of the problem is crucial for finding the right solution. One of the most common causes is an air leak in the suction side of the system. Air leaks can occur in the skimmer, pump, or suction hose, and they can cause the pump to lose its prime and stop working.
Clogged skimmer baskets or pump baskets can also cause a pool pump to not prime. Debris can accumulate in these baskets, blocking the flow of water and preventing the pump from priming. A low water level in the pool can also cause a pool pump, not to prime. If the water level is too low, the pump may not have enough water to prime itself.
Another possible cause is a faulty or damaged impeller. The impeller is responsible for moving the water through the pump and filter, so if it is damaged or not working properly, the pump may not prime. Lastly, a clogged or damaged filter can also cause a pool pump, not to prime. A clogged filter can reduce the flow of water, and a damaged filter can cause leaks, both of which can prevent the pump from priming.
Diagnosing the Problem
Once you have an idea of what might be causing your pool pump, not to prime, the next step is to diagnose the problem. The first step is to check for air leaks in the suction side of the system. This can be done by examining the skimmer, pump, and suction hose for any visible cracks or holes.
Another step is to inspect the skimmer basket and pump basket for any clogs or debris. If these baskets are clogged, they will need to be cleaned or replaced. The next step is to check the water level in the pool. If the water level is too low, it will need to be refilled.
You should also inspect the impeller and filter. If the impeller is damaged or not working properly, it will need to be replaced. If the filter is clogged or damaged, it will need to be cleaned or replaced.
Solutions to Fix the Problem
Now that you have diagnosed the problem, it’s time to find a solution. If the problem is an air leak, the solution is to fix the leak. This can be done by patching up any cracks or holes in the skimmer, pump, or suction hose. If the problem is a clogged skimmer basket or pumps basket, the solution is to clean or replace these baskets.
If the problem is a low water level, the solution is to refill the pool. If the problem is a faulty or damaged impeller, the solution is to replace the impeller. And if the problem is a clogged or damaged filter, the solution is to clean or replace the filter.
Preventing the Problem in the Future
Preventing the problem from happening again in the future is an important step in maintaining your pool pump. Regular maintenance and proper care can go a long way in keeping your pool pump in good working condition. One of the most important preventative measures is regular cleaning of the pool pump and system.
This includes cleaning the skimmer basket and pump basket, as well as inspecting and cleaning the impeller and filter. Properly balancing the chemicals in the pool is also crucial for the health of the pool pump and the overall health of the pool.
Keeping the pool clean and free of debris can also help prevent clogs and damage to the pool pump. Additionally, it’s important to properly winterize the pool pump and system to protect it from damage during the off-season.

Troubleshooting the Priming Issue
If you’ve followed the steps above and your pool pump still won’t prime, there are a few more things you can try. Firstly, check the power supply to the pump. Make sure it is plugged in and that the circuit breaker hasn’t tripped. Secondly, inspect the pump strainer lid for proper seal.
A loose or damaged lid can cause air leaks and prevent the pump from priming. Thirdly, check the pool return jets for proper flow. If the return jets are clogged or not working properly, they can prevent the pump from priming. Fourthly, verify that the pump is set to the correct speed.
If the pump is set to a low speed, it may not have enough power to prime. Lastly, check for clogs or kinks in the suction hose. If the suction hose is clogged or kinked, it can reduce the flow of water and prevent the pump from priming.
When to Call a Professional
Despite your best efforts, there may be times when your pool pump won’t prime and you’re not sure what to do. In these cases, it’s best to call a professional for help. If the problem persists despite your troubleshooting efforts, it’s best to call a professional.
If your pool pump is under warranty, contact the manufacturer or a professional for repair or replacement. If the problem is determined to be caused by a major component such as a broken seal or motor failure, it’s best to call a professional for repair or replacement.
And if you lack the necessary knowledge or tools to properly diagnose and fix the problem, it’s best to call a professional for help.
Conclusion
A swimming pool pump that won’t prime can be a frustrating problem, but it’s one that can be fixed with a little knowledge and effort. Understanding the causes of a pool pump not priming, how to diagnose the problem, and solutions to fix the problem is crucial for getting your pool pump back in good working condition.
Regular maintenance and proper care can also help prevent the problem from happening again in the future. And when in doubt, call a professional for help.
A well-functioning pool pump is crucial for the overall health and safety of the swimming pool and its users. It’s important to know that taking care of the pool pump and maintaining it in good working condition will not only ensure you have a clean, clear, and safe pool to swim in, but it will also save you from costly repairs in the future.
