How to Clean Pool Jets for Stronger Water Flow

When your pool jets start to feel weaker than usual, it is a sign that your circulation system may be struggling. Cleaning your jets regularly can restore water pressure, prevent dead zones, and keep your pool feeling fresh and comfortable.

What Are Pool Jets and What Do They Do?

Pool jets are the small openings that shoot water back into your pool after it has been filtered. They play a major role in maintaining water movement, distributing heat and chemicals, and helping push debris toward your skimmer.

When they become clogged or blocked, water circulation slows down and your pool may develop cloudy areas, algae, or poor heating.

Why Do Pool Jets Get Dirty or Clogged?

Over time, jets can build up:

Algae or biofilm
Scale from hard water
Small debris or sand
Sunscreen, oils, or lotions

These materials can restrict the flow of water and make your filter and pump work harder than necessary.

When Should You Clean Your Pool Jets?

You should clean your pool jets when you notice:

Weak water flow
Dead spots in the pool
Uneven circulation or cold areas
Jets spraying in odd directions

It is also good practice to clean your jets:

Once every month during swim season
After an algae bloom
After a major storm or heavy pool usage

How to Clean Pool Jets Step by Step

Step 1: Turn Off the Pool Pump

Always begin by shutting off the power to your pump. This prevents injury and keeps debris from getting pushed deeper into the lines.

Step 2: Remove the Jet Nozzles

Use a jet removal tool or simply unscrew the nozzles by hand. Be gentle to avoid cracking or damaging the fittings.

Step 3: Soak the Jets

Prepare a bucket with a cleaning solution:

1 part white vinegar or mild pool-safe cleaner
2 parts warm water

Soak the jet nozzles for 1 to 2 hours. This loosens scale, oils, and organic buildup.

Step 4: Scrub and Rinse

After soaking:

Use an old toothbrush or soft-bristle brush to scrub inside and around the jets
Rinse thoroughly with clean water

Do not use metal tools or wire brushes, which can scratch the plastic.

Step 5: Flush the Jet Lines

Before replacing the jets:

Turn the pump on briefly to flush the lines
This pushes out any debris trapped behind the jets

Shut the pump back off once flushed.

Step 6: Reinstall the Jets

Screw the clean jets back into place and restore the pump power. Test the water flow. You should see a noticeable improvement.

What Products Can Help With Jet Maintenance?

To keep your pool jets clean longer, try these options:

Jet line cleaner: Designed to dissolve buildup in circulation lines
Enzyme treatments: Break down oils and lotions
Scale preventers: Help avoid mineral deposits from hard water
Regular shocking: Eliminates organic waste before it clogs the system

Using these weekly or bi-weekly makes cleaning easier and less frequent.

Who Should Clean Pool Jets?

Most pool owners can clean their jets themselves. However, call a professional if:

Your jets will not unscrew easily
You suspect plumbing clogs deeper in the return lines
Water pressure remains weak even after cleaning

A pool technician can perform a deeper flush or inspect your pump and filter system.

How to Keep Water Flow Strong Year-Round

Clean the filter regularly
Backwash sand or DE filters when needed
Remove leaves and debris from skimmers daily
Check for air leaks in your pump system
Run your pump for 8 to 12 hours a day
Brush your pool walls weekly to prevent buildup

Taking these steps ensures that your clean jets stay effective, keeping your pool fresh and ready for swimming.

With just a few minutes of attention, clean pool jets can make a huge difference in water clarity, comfort, and circulation.
