How to Stop Air Bubbles from Forming in Your Pool
Here’s Everything You Need To Know
Do the return jets of your pool have air bubbles coming out of them? If so, do not be alarmed because it’s a problem that happens often. Here are some troubleshooting tips to help you deal with this problem.
Why Am I Getting Air Bubbles?
In most cases, the side of your pool has a suction area where the air comes out from. Check the following accessories to verify that you have air in your system:
1) Pool Skimmer
Analyze the water level of your pool. If it is low on water, then your skimmer is probably sucking up a lot of air. The water level should be within the center of the opening of the skimmer.
Analyze the skimmer basket to see if it’s damaged. It should also be seated correctly so that the water suction is good.
Analyze the weir, which is the flapping door of the skimmer. The weir is in front of it. The purpose of the weir is to prevent big pieces of debris from finding their way into the pool again. The weir manages the flow of water that goes into the skimmer too. If the weir is ever jammed, unjam the door to get it moving freely again.
You don’t need a skimmer weir if you don’t have one already, but it is better to have one.
2) Pool Pump
Analyze the lid of the pump. If you see any cracks, then you have a big issue to deal with. Usually, the O-ring of the lid is the problem.
Shut off the pump and take off the lid. Analyze the O-ring and see if it has any cracks. Use your fingers to bend the O-ring, and you’ll be able to tell whether it has cracks or not. If the O-ring has signs of dry rot or splitting, then replace it immediately. If you don’t see cracks anywhere, then you can feel good about it.
It is best to use an O-ring lubricant that is Teflon-based because it will produce a stronger seal.
Analyze the pump basket to see if it’s cracked. The basket will not be seated properly within the housing if there are cracks present. In this case, replace the basket and clean it regularly. Also, make sure it is seated correctly in the housing because this will allow you to seal the lid correctly too.
Analyze the drain plugs of the pump housing. There should be one or two plugs to check. Ensure they’re not loose or leaking in any way. If they are, then use a little plumber’s tape to seal the threads of the drain plug. This should stop the leakage.
The plumbing of an inground swimming pool could have unions in it. The word “unions” refers to threated connectors which exist in the middle of the piping. Their purpose is to let filter equipment be replaced easily so that you don’t need to cut any of the pipes.
There is an O-ring inside of each union. Make sure it does not have damage or cracks either. If you see this kind of damage there, then replace the O-ring right away. If you don’t see any damage, then check to ensure the O-ring is seated correctly within the appropriate grooves. The O-ring must be in its groove or else it won’t seal properly. If it’s not sealed properly, then air will find its way into your pool system.
