Pool Pump Leaking After Replacing Shaft Seal (Solved)

One of the main concerns people deal with when it comes to using a pool pump is when it begins leaking.

It is difficult to pinpoint why the pool pump is leaking and where the damaged part is.

For the most part, it is going to be something to do with how the water flows through the pool pump and which part is damaged. It is often going to be the seal.

This is when you are going to want to go back and take a look at the seal. However, what if the pool pump is leaking after replacing the shaft seal?

If the pool pump is leaking after replacing the shaft seal, go back and re-install it. If this does not work, check the pump impeller for damage and inspect the pump housing for an underlying crack. In some cases, the O-Ring will get damaged and need to be replaced.

In general, the main issue is going to do with damage to a specific part outside the shaft seal of a pool pump.

You will want to work through these steps to see where the issue lies.

This article is going to look at what’s required when fixing a pool pump leaking after replacing the shaft seal.

Steps On Fixing Pool Pump Leaking After Replacing Shaft Seal

1. Re-Install The Shaft Seal

When the issue arises after replacing the shaft seal, you will want to go back and take a look at the part again.

Sometimes, the initial installation is not going to turn out as required.

This means the seal is not going to be stable and it will need to be redone.

This is normal and the best thing a person can do is re-install it. This will ensure things progress as you need and you can then take a look at the other parts of the pool pump moving forward.

Do not look past the shaft seal of a pool pump until you have at least re-installed it once. This will then give you a heads-up about other issues that you might be facing.

2. Check The O-Ring For Cracking

You are now going to take a look at the rest of the pool pump.

One issue that people report has to do with the O-ring.

This ring is put around the seal and it is essential for how well the seal works. If it does not hold, the rest of the seal is not going to do much for the pool pump.

The leaking will begin right away and it will become difficult to stop until you replace the O-ring. If this happens and you do notice damage to the O-ring in a pool pump, it’s best to replace it on the spot.

3. Look At The Pump Impeller

Let’s assume everything around the seal is good, you are now going to venture outward.

You are going to take a look at the rest of the pool pump.

This is going to include the pump impeller.

You don’t want a situation where the pump impeller is damaged as that is going to become a real problem for those who want to do things the right way.

It’s essential to see what is going on with the pump impeller and how well it works over time. As long as you are doing this, you are going to get the pump impeller to run in a way that works.

4. Focus On The Pump Housing

The pump housing is something you are going to want to think about in greater detail.

The pump housing is essential in how well the pool pump holds up. This is why you are going to start noticing the leaking.

Once this gets damaged, the water will leak through.

You have to figure out where the crack or damaged part is with the pump housing. As soon as you spot this, you will know it is going to have to be replaced.

Final Thoughts

The best thing a person can do is take a look at what’s going on with the pool pump to see why it’s leaking after replacing the shaft seal.

If the pool pump is leaking after replacing the shaft seal, it’s best to re-install the shaft seal to see if that helps. If not, replace the O-ring and check parts such as the pump impeller or pump housing for potential cracking.

It is common for those to be the issues that are going to arise when the pool pump is leaking.

You do not want to rush the process but changing the damaged part is often the way to go. You will want to get the pool pump back to how it was and it is these parts that tend to get compromised.

Work your way outward from the shaft seal to get good results.
