To fix the pool pump losing prime when turned off, it’s best to turn off the pump, listen for a hissing noise (air leak), find the leak, and then fix it. The most common places for the leak are the fitting filter or the pump lid.

It’s important to note that each scenario is different.

This article is going to look at how to fix a pool pump losing prime when turned off.

How To Fix Pool Pump Losing Prime When Turned Off

1. Turn Off The Pool Pump

It is possible you can find the air leak without turning off the pool pump.

However, it is safer and faster to do this as it will allow you to focus on where the sound is coming from. Due to the nature of an air leak, it can happen anywhere within the setup and you are going to have to find its precise position to fix it.

To do this, the best solution is to turn off the pool pump.

Once you turn off the pool pump, you are going to have complete access to the air leak.

Take the time to find out where the air leak is coming from and then look at that particular spot. In most cases, the air leak will be easy to pinpoint and you will then need to start working on a fix.

2. Listen For Hissing Noise

When the pool pump is not working well, it is going to start generating a hissing noise.

This is a warning sign.

It is possible things could get worse if you don’t take the time to be proactive with the solution. You will want to nip the problem in the bud by stopping the air leak instantly.

This can be done depending on what the issue is.

The goal is to find where the hissing noise is and then inspect that part of the setup.

This will let you gauge what can be done for the pool pump and why that noise keeps coming. If there is no hissing noise, you might be dealing with a damaged pool pump.

3. Check For Leak Near The Pump Lid Or Filter Fitting

Let’s assume you have found the air leak.

You are now going to know it will either be near the pump lid or the filter fitting. Due to the nature of how the air leak happens, it can be anywhere in the setup and that is what confuses pool owners.

The best option is to follow the hissing sound.

This is how you are going to know whether or not the problem is near the pool pump lid or the filter fitting.

As soon as you find the air leak, you are then going to inspect how bad the situation is. Can it be patched up? Is it due to a loose lid?

This will guide you toward a particular solution.

4. Fix The Leak

The most important step is to fix the leak.

The air leak is not going to go away on its own and you will need to be productive with the solution. The easiest option is to replace the damaged part.

This might be the only option depending on how severe the air leak is.

The first option would be to swap out the part with a new one. Another solution is to tighten the part if it is the pool pump lid as that might be the reason for the air leaking.

It does not always have to be damaged.

As you are working on the pool, you are going to have to be diligent about your strategy. Look at all of the pool parts and then figure out how you are going to manage the air leak.

Final Thoughts

These are the details you will want to consider when the pool pump is losing prime when turned off.

If the pool pump is losing prime when turned off, this means there is an air leak in the filter fitting or the pool pump lid. Start by turning off the pool pump, inspecting the filter fitting, and then waiting for the hissing noise. After the hissing noise is located, patch up the air leak.

This will help get the pool pump to work as you want it to.

Until you do this, the air leak is going to get worse and the hissing noise will become increasingly noticeable. Do not let this happen.
