Why Does My Pool Have Air Bubbles and How Can I Fix It?

Now your pool is installed in your backyard, everyone in the family is looking forward to plunging in. The pool looks great, but there’s one thing that bothers you. There are bubbles in the water. Before assuming something is seriously wrong, it helps to understand that the reason for those bubbles is likely something that can be easily repaired. Here are some ideas for you to check.

Are You Really Seeing Air Bubbles?

Before spending too much time looking for the origin of your air bubbles, make sure they actually are bubbles. Depending on your jet design, you may be seeing froth rather than bubbles. This type of situation can occur when the minerals in the water are unbalanced.

Froth is most often caused by low calcium hardness in your pool water. In other words, the lack of mineral content in the water has made it soft, which allows froth to develop. You can easily remedy this situation without making any repairs to your pool or equipment.

You just need to add calcium chloride to the water. After doing so, the water chemical balance and make sure it complies with your pool manufacturer’s recommendations. Once the balance is back within a normal range, the froth will subside and you’ll see nothing but clear water you’ll just want to (and can!) dive into.

Investigate the Jets

The jets in any swimming pool design help return water that’s passed through the filters. Climb into your pool and study each jet. Observe the water as it emerges and see there are air bubbles in it.  If so you’ve found your problem.

Water emerging from jets shouldn’t have any signs of air bubbles. Their presence indicates there’s something going on with your pool’s filtration system. Your job now is to learn why air is getting into what should be a closed system.

Study the Filtration System

Now you know the air bubbles are originating in the filtration system, check the filters and the equipment that comprise the system. Your first order of business should be the fittings found on both the intake and the return pipes of the filtration pump.  There’s a good chance one or more of those fittings is loose or possibly damaged.

On the intake side, check the fitting to make sure the seal is tight.  Use a wrench to see if it will turn slightly. If so you can tighten the fitting and the problem may go away. If the fitting is tight, the problem could be further along the line.

Check the out-take from the pump and determine if those fittings are solid and also sealed perfectly. If not, tighten them and observe the water gushing from the jets. If the air bubbles are gone, congratulations! You’ve solved the problem and the system is working as it should.

The Seal around the Filter Pump Lid

Another possible reason for air bubbles is a problem with the seal of the lid on the filtration pump. Like the fittings, the lid should be completely secured and airtight. If the seal is slightly warped or otherwise damaged, it won’t provide the efficiency you need. Your best bet is to have it replaced at once. This will alleviate stress on the pump and ensure the air bubbles are no longer present.

The Pump Housing

Another area to check is the housing on the filtration pump. Scrutinise the drain plugs on the housing. If they appear clogged for any reason, that could be the underlying cause of the bubbles.  Clearing the drains and restoring proper function may be all it takes to fix the problem.

When to Call For Help

Sometimes, despite your best efforts you simply won’t be able to find or fix the problem. Rather than trying to deal with the issue on your own, the best bet is to call a professional. Explain your problem and the steps you’ve taken to deal with it. That information will go a long way in helping the professional eliminate the more common reasons for the bubbles.
