If your pool pump is squealing in cold weather when you turn it on this indicates that you have an issue with the bearings.
Lower temperatures restrict the flow of lubrication around the bearings.
This causes increased friction which is responsible for the squealing noise, it can also cause a lot of damage and can lead to pump failure so should be fixed as soon as possible.
Typically squealing noises will happen when the pump is first turned on, it will usually last for up to 30 minutes.
The noise eventually goes away as the bearings warm up the movement inside the pump becomes smoother and the noise disappears.
However if you allow the pump to cool down and then restart it again the noise will begin once again.
As we've said this noise is caused by faulty bearings.
Sometimes this noise may be so loud that you can hear it inside your home or even outside in the yard!
The good news is, there are things that you can do to eliminate these squealing noises from your life:
This is probably the best solution to this problem.
The bearings are what cause your pool pump from squealing when cold so it makes sense that if you replace them, then there will be no more noise! This may seem like a lot of work but changing out these small components won't take too long and can save you a lot of trouble in the future.
To do this yourself here's what you need to do (this guide is for on a Hayward pool pump):
First you will need the following:
As you can see from the previous step manually replacing the bearings yourself is no easy task.
If your pump is still in warranty then a quicker and far easier solution is to get the whole pump replaced.
This is more of a short-term strategy however if you need to use your pool pump today and you don't want to make unnecessary squealing noise then this can work very well.
In cold weather the oil around the bearings doesn't lubricate them as well causing more friction.
Warming the pump up before you use it will help prevent this and will reduce viscosity and allow the bearings to move easily and far more quietly.
The best way to warm up your pool pump is by using the sun...i.e waiting until the weather warms up and then turning it on, however if this is not an option then a heat lamp can work very well.
Place the heat lamp over the pool pump within a couple of feet from it. Give it 20-30 minutes of heat before turning off the heat lamp and starting the pool pump up.
