How do I maintain a jetted bathtub?

Jetted tubs are a great feature, but they do require regular maintenance to keep the jets clean and the system running properly. The biggest issue most homeowners face is biofilm buildup inside the jet lines — a slimy residue from soap, body oils, and bacteria that accumulates in the plumbing you can't see.

Cleaning the Jet Lines (Monthly)

The most important maintenance task is flushing the internal plumbing. Fill the tub with hot water until it covers the jets by about 5 cm, then add 2 tablespoons of low-foaming dishwasher detergent and ½ cup of white vinegar or a dedicated jetted tub cleaner. Run the jets for 15 minutes, drain, refill with cold water, and run for another 10 minutes to rinse. You may be surprised — and a little disgusted — by what comes out the first time you do this.

Wiping Down the Jets and Surfaces

After each use, wipe down the tub surround and jet bezels with a soft cloth. Avoid abrasive cleaners or scrubbing pads on acrylic tubs, as they'll scratch the surface and make it harder to clean over time. A mild bathroom cleaner or diluted white vinegar works well for routine wipe-downs.

Keeping the System Healthy

Run the jets briefly with clean water every few weeks even if you're not using the tub regularly — stagnant water in the lines accelerates biofilm growth. Check the air intake cover (usually near the jets) periodically and clean out any debris. If you notice reduced jet pressure, unusual noises, or persistent odours despite cleaning, that's a sign the pump or plumbing may need professional attention.

In Ottawa's climate, hard water mineral deposits can also build up in jet systems over time. A periodic flush with a citric acid-based cleaner helps dissolve calcium buildup, especially if you're on municipal Ottawa water.

If your jetted tub is showing signs of wear — cracked jets, leaking seals, or a failing pump — those repairs are best handled by a licensed plumber or renovation contractor.
