If you’re asking the question, “Do I have air in my pool pump?” it’s probably because you are seeing bubbles shooting out of the return jets in your swimming pool and you suspect that this isn’t quite right.

If this is you, then you’re completely on the right track. The jets in your swimming pool should be pushing out a steady stream of water, minus debris, and air bubbles. 

Checking for air in my pool pump

Fortunately, this isn’t one of the biggest issues in the world and for the most part, the problem can quickly be identified and fixed. 

So where do we start?

Logically, we have to assume that air is being sucked into the system where it shouldn’t be. There are a few likely places to start. 

Take a careful look at where your pool water is going; carefully examine the skimmer and baskets to check that there is no damage or blockages. You’ll want to make sure that the water level is high enough and that all the sucking parts are underwater. You may simply need to top up the water level and empty the filter baskets. 

If this all checks out, then your next port of call will be the pump itself. Weathering of the pump housing can result in cracking, and if you see a cracked lid then there’s your problem. However, the most common issue is a cracked O-ring which serves as your trusty seal beneath the lid. These do need replacing every so often and if it’s showing signs of wear, splitting or rotting, then grab yourself a new one and squirt it with a little lubricant when you install it. 

Older pools may need a little more TLC when it comes to the plumbing to and from the pump. Over time, the pipe connectors can lose integrity and may require replacement seals. Most well-installed swimming pools will have easy-to-access unions where you can check the system without digging up your garden.
