Is your faucet running slower than usual? Or maybe your shower suddenly has weak pressure? If so, you could be dealing with sediment in your pipes—a major cause of low house water pressure.

In places like Fresno, Modesto, Riverside, and other California cities, this issue is becoming increasingly common due to aging water systems and hard water deposits. In this blog, we’ll explain what causes sediment in pipes, how to clean them out, and when to call Phoenix plumbers today for expert help.

What Is Sediment in Pipes?

Sediment refers to mineral deposits like calcium, magnesium, rust, or even sand that build up inside your plumbing system over time.

These materials collect in your pipes, fixtures, and appliances—restricting water flow and leading to low house water pressure. The longer sediment builds up, the worse the flow becomes, and the higher your chances of experiencing clogs or pipe damage.

Common Causes of Sediment Buildup

Understanding where the sediment comes from helps you prevent it. Here are the top culprits:

1. Hard Water

Hard water is full of minerals like calcium and magnesium. Cities such as Bakersfield, Fresno, and Stockton experience high mineral content in their water supply. Over time, these minerals crystallize and cling to pipe walls.

2. Aging Pipes

Older pipes—especially galvanized steel—are prone to rust and internal scaling. This sediment flakes off and slows water flow.

3. Municipal Water Supply

City water systems may carry fine sand or silt, especially during pipeline repairs or after storms. Cities like Long Beach and San Bernardino have seen spikes in sediment problems after maintenance work.

4. Water Heater Corrosion

Sediment in your water heater can enter your plumbing system and create blockages throughout your home.

Signs You Have Sediment in Your Pipes

Here’s how to know it’s time to flush those pipes:

• Sudden low water pressure in one or more faucets

• Discolored water (brown, yellow, or cloudy)

• Clogged aerators and showerheads

• Popping or hissing sounds from your pipes or water heater

• Slow-filling toilets or appliances

If these issues sound familiar, you might have sediment buildup.

How to Fix Sediment in Pipes – Step-by-Step

If your water pressure is dropping and you're seeing signs of buildup, here’s how to get things flowing again.

Step 1: Shut Off the Main Water Supply

Always begin by shutting off the main water valve. This prevents any water damage and allows safe cleaning of your plumbing system.

Step 2: Open All Faucets

Open all hot and cold water taps to drain the system. This helps remove loose debris and prepares the pipes for cleaning.

Step 3: Remove and Clean Aerators

Faucet aerators catch sediment before it enters the fixture. Unscrew and clean them using a small brush and vinegar to break down the minerals.

Step 4: Flush the Water Heater

If your home has a water heater, sediment might be settling at the bottom of the tank.

• Turn off the heater.

• Connect a hose to the drain valve.

• Drain the water completely.

• Rinse until water runs clear.

This is especially important in homes with hard water, like in Riverside and Santa Ana.

Step 5: Use a Vinegar Flush (If Pipes Allow)

White vinegar is a natural cleaner that breaks down mineral deposits. Fill the pipes with vinegar and let it sit for several hours before flushing with clean water.

Warning: Do not use vinegar if you have old copper or iron pipes. It could cause corrosion. Always consult a professional if unsure.

Step 6: Consider Pipe Descaling or Jetting

For stubborn buildup, professional services like pipe jetting or descaling may be necessary.

• Pipe Jetting: High-pressure water blasts clear out the pipes.

• Descaling: Specialized tools scrub the interior walls of your plumbing system.

These services are often offered by phoenix plumbers today and are highly recommended in homes with extensive buildup or frequent low pressure issues.

Preventing Future Sediment Buildup

You don’t want to go through this more than once. Here’s how to avoid future issues.

Install a Whole House Water Filter

These systems capture sand, silt, and minerals before they reach your pipes.

Use a Water Softener

In hard water areas like Fresno or Bakersfield, water softeners remove excess minerals and reduce scale formation.

Perform Annual Plumbing Maintenance

Have a licensed plumber inspect your system annually. They can identify early signs of sediment buildup and flush the system before problems arise.

Flush the Water Heater Every 6–12 Months

Regular flushing reduces mineral buildup and extends the life of your heater.

Clean Faucet Aerators Monthly

Prevent blockages by checking and cleaning aerators often. It’s a quick task that can improve flow instantly.

Cities in California Most Affected by Sediment Problems

Several cities in California frequently report sediment buildup due to aging infrastructure and hard water supply:

• Fresno – High mineral content and aging water lines.

• Bakersfield – Among the worst for hard water problems.

• Modesto – Water main repairs stir up sediment in the system.

• Riverside – Residents often report low water pressure and cloudy water.

• Stockton – Older homes experience corrosion and scaling.

• Santa Ana – Water quality reports show moderate to high hardness levels.

• Oxnard – Increased sand and grit from coastal water sources.

If you're in one of these cities and dealing with frequent plumbing issues, it's time to check your pipes.
