Faucet Spraying Water? Here’s Why It Happens and How to Fix It

If your faucet is suddenly spraying water sideways, spitting in random directions, or putting out a weak, scattered stream – take a breath. In most cases, you’re dealing with a clogged aerator, and it’s a five-minute fix you can handle yourself. If you live in Anaheim or anywhere across Orange County, this problem is more common than you might think. Our water supply runs hard – roughly 15 grains per gallon from the Santa Ana River basin – and that mineral load builds up inside faucet aerator screens faster than in softer-water regions. Here’s how to figure out what’s going on, clean the aerator step by step, and know when it’s time to call in a licensed plumber.

Key Takeaways

  • Air trapped in your plumbing lines can also cause spitting or sputtering – especially after a water main shutoff or nearby plumbing work
  • There are two aerator types: standard and recessed – knowing which one you have before you start saves time and frustration
  • The same vinegar soak that clears a faucet aerator works for clogged shower heads too
  • Replace the aerator if the mesh is torn, the o-ring is cracked, or the spray doesn’t improve after a thorough cleaning
  • OC homeowners should plan to clean aerators every 6 months to stay ahead of hard water buildup

Why Is Your Faucet Spraying Water? The 3 Most Common Causes

Before you grab a wrench, it helps to know which problem you’re dealing with. The spray pattern and timing give you the best clues.

1. Air Trapped in the Plumbing Lines

When air gets trapped in your water lines, it disrupts the flow and can cause spitting, sputtering, or uneven pressure. You might also hear banging or tapping behind the walls. This usually shows up right after the water main has been shut off and turned back on, or after nearby plumbing work has been done. If multiple fixtures are acting up at the same time, trapped air is the likely culprit.

2. Clogged or Damaged Aerator

The aerator is the small mesh screen screwed onto the tip of your faucet. Its job is to mix air into the stream of water for a smooth, even flow. When mineral deposits, sediment, or debris block part of that screen, water gets redirected – and it can spray sideways, spit, or come out in an uneven pattern. This is the most common cause of a faucet spraying water in Anaheim homes, especially given the hard water from the Santa Ana River basin.

3. Water Pressure Issues

Sudden spikes or drops in water pressure can also change how a faucet behaves. If the spraying is happening at just one fixture, it’s almost certainly a localized issue – usually the aerator. If multiple faucets throughout the house are acting up, you may be dealing with a pressure regulator issue or a supply line problem that warrants a professional look.

How to Bleed Air From Your Plumbing Lines

If you recently had the water shut off or had plumbing work done, air in the lines is probably to blame. Here’s how to clear it:

  1. Make sure the water main is fully open. Turn the valve all the way counterclockwise, or flip the lever to the fully open position.
  2. Find the fixture closest to the main water supply and start there.
  3. Work through the house in order, opening each faucet – both hot and cold – about a half turn. Do this for toilets, showers, tubs, and appliance connections like the washing machine.
  4. Let each fixture run until the water flows smoothly and steadily without spitting.
  5. Close each fixture in the same order you opened them.

Running all fixtures at once builds enough force to push remaining air through and out of the system. Once the water runs clean and steady from every fixture, you’re done.

How to Fix a Faucet Spraying Water: Clean the Aerator

If the faucet is still spraying after you’ve bled the lines – or if the issue appeared gradually rather than all at once – the aerator is almost certainly the problem. This is the most common cause we see when servicing faucets in Anaheim and OC homes, and it’s an easy fix.

What You’ll Need:

  • Pliers (wrap the jaws with a cloth to protect the faucet finish)
  • An aerator key for recessed models (more on that below)
  • A small bowl
  • White vinegar
  • An old toothbrush

Step-by-Step Aerator Cleaning:

  1. Remove the aerator. Twist it counterclockwise by hand. If it’s stuck, use cloth-wrapped pliers. For recessed aerators that sit flush with the faucet tip, use an aerator key – see the next section.
  2. Disassemble the components. The aerator contains a few small parts: a mesh screen, a flow restrictor, a rubber washer, and an o-ring. Keep them in order so reassembly is easy.
  3. Inspect everything. Look for torn mesh, cracked housing, or a damaged o-ring. If any part is physically broken, it needs to be replaced, not just cleaned.
  4. Soak in white vinegar for 20–30 minutes. Submerge all parts in a bowl of white vinegar. The acid dissolves calcium and mineral deposits without damaging the components.
  5. Scrub with the toothbrush. After soaking, scrub each piece gently to remove any remaining buildup. Rinse everything thoroughly under warm water.
  6. Reassemble in the correct order and screw the aerator back onto the faucet tip. Hand-tight is fine.
  7. Test the faucet. Turn the water on slowly and check the stream. It should be smooth and even.

If you’re in Anaheim, Garden Grove, Fullerton, or anywhere else in Orange County where the water runs hard, plan to clean your aerators every 6 months or so. The mineral buildup comes back faster here than in soft-water regions, and staying ahead of it prevents a lot of frustration.

Standard Aerator vs. Recessed Aerator: Which One Do You Have?

Knowing your aerator type before you start saves a lot of frustration. There are two common styles:

  • Standard aerator: Sticks out slightly from the faucet tip and can be removed by hand or with pliers.
  • Recessed aerator: Sits flush inside the faucet spout and requires an aerator key (also called a cache aerator key) to remove.

Recessed aerators are common on newer kitchen faucets and many modern bathroom faucets. Aerator keys usually come with a new faucet or are available at any hardware store for around $10. If you’re unsure which key you need, check the manufacturer’s name on the faucet.

When to Replace the Aerator Instead of Cleaning It

Cleaning solves mineral buildup – but sometimes the aerator itself needs to go. Replace it if you notice any of the following:

  • The mesh screen is physically torn or corroded through
  • The o-ring is cracked, flattened, or missing
  • The housing is cracked or warped
  • The spray pattern doesn’t improve even after a thorough vinegar soak and scrubbing

Standard replacement aerators run about $5–15 and screw directly onto the faucet tip. Most home improvement stores carry them, and the correct size is usually stamped on the aerator housing. If you’re unsure which size you need, bring the old one with you to the store.

Does the Same Fix Work for Shower Heads?

Yes – the same mineral buildup that clogs faucet aerators affects shower heads too. Fill a plastic bag with white vinegar, secure it around the shower head with a rubber band, and let it soak for 20–30 minutes. Remove the bag, run the water for a minute to flush everything out, and check the spray. If the pressure still doesn’t improve, the issue may be internal – a worn cartridge or pressure regulator – and worth a call to a plumber.

Faucet Still Spraying Water After Cleaning the Aerator?

If you’ve cleaned the aerator, bled the lines, and the faucet is still acting up, something deeper is going on. These are the specific signs that point to a problem a DIY fix won’t solve:

  • Water pressure fluctuates throughout the whole house, not just at one fixture
  • The water is discolored or gritty – a sign of pipe corrosion, which is more common in older Anaheim homes with original galvanized supply lines
  • The shut-off valve under the sink won’t fully close
  • You replaced the aerator and the spray pattern is still uneven
  • The faucet is leaking around the base or handle

Any of these situations calls for a licensed plumber to take a look at the supply line, pressure regulator, or faucet cartridge.

Faucet Spraying Water FAQs

Why is my faucet suddenly spraying water sideways?

The most common cause is a partially blocked aerator – the mesh screen at the tip of your faucet. Mineral deposits or debris can redirect the flow sideways. Remove and clean the aerator first; if the problem continues after cleaning, the aerator likely needs to be replaced.

How do I clean a faucet aerator?

Unscrew the aerator, disassemble the components (screen, flow restrictor, rubber washer, o-ring), and soak everything in white vinegar for 20–30 minutes. Scrub with an old toothbrush, rinse well, reassemble, and reattach. The spray pattern should return to normal.

Why does my aerator keep clogging so quickly?

Anaheim and Orange County water runs at roughly 15 grains per gallon – classified as very hard – which deposits calcium and magnesium scale inside aerator screens faster than in soft-water areas. Cleaning every 6 months helps; a whole-house water softener can reduce buildup long-term.

When should I call a plumber instead of cleaning the aerator?

Call a plumber if water pressure fluctuates throughout the house, the water is discolored or gritty, the shut-off valve under the sink won’t fully close, or a new aerator doesn’t fix the problem. These point to a supply line, pipe corrosion, or pressure regulator issue that needs professional diagnosis.

Can hard water cause my faucet to spray water?

Yes – Anaheim and Orange County water runs around 15 grains per gallon, which is considered very hard. That mineral buildup builds up faster inside aerator screens than in soft-water regions, making clogged aerators one of the most common faucet problems we see across OC.
