It’s that time of year again, when we see articles giving advice on how to open your pool. They list cleaning and cover maintenance ideas, pump and equipment tips, and water chemistry routines to help you get started.
None of the ones we’ve seen talks about the annual maintenance of your pool ozone generator, though. So we are filling the gap here with a few basic tasks you should do to ensure that your ozone system is working away silently and automatically to keep your pool water fresh and sparkly.
Monthly Maintenance Tasks
When the pool pump is running and the ozonator is turned on, the indicator lights should be green. If they are red or not glowing at all, check the power supply. If there is still power, you may have an ozone cell problem.
Observe the outlet of the return line where it enters the pool while the pump is running and the ozone system is on. You should observe a stream of tiny bubbles. If you cannot see the bubbles, disconnect the ozone delivery tube from the ozone generator, and by putting the tip of your finger over it while the pump is running, you should feel a tiny tug that indicates there is vacuum. If you do not feel the vacuum, either there is not enough water flowing through the return line or there is a blockage in the ozone delivery tube.
Check the ozone delivery tube, including around the check valve. The check valve must be installed in the proper direction, with the arrow pointing toward the injector valve. If there are signs of water around the check valve, or above it, stop the system immediately and replace the check valve and ozone supply tubing.
Annual Maintenance Tasks
It is a good idea to replace the ozone supply tubing and check valve annually. These inexpensive parts are critical to effective operation, and they can deteriorate. If there is a leak at any point of this line, insufficient ozone will be delivered to the pool.
About every two years, give or take, you may need to replace the ozone cells. DEL Ozone corona discharge ozonators are durable and highly reliable, but they have a life of about 15,000 hours runtime. Depending on how often your pump runs, you may reach this level in two years (of course, knowing your pump timing, you can estimate the number of hours the ozonator runs every day/month/year). If you have a lesser ozone system, you may need to replace the ozone cell more often.
Give yourself safe, enjoyable water and peace of mind with these basic ozone maintenance steps.
