Highlights

  • Sediment can collect in your water heater and lower its efficiency.
  • Your dishwasher may clean poorly if spray arms or valves get blocked.
  • Washing machines fill slower and wear out faster when screens clog.
  • A fridge with a water line needs clean filters to avoid flow problems.
  • Basic checks and cleaning every few months help prevent long-term damage.


Sediment is made up of small particles like sand, minerals, and rust that travel through your water supply. Over time, this buildup can collect inside your appliances and reduce how well they work. In some cases, it can shorten their lifespan or cause costly damage.

Here are the four appliances most affected by sediment buildup and how you can protect them with simple, regular upkeep.

1. Water Heater

Your water heater is one of the most affected appliances. It holds water for long periods, which gives sediment time to settle at the bottom of the tank. This buildup can reduce heating efficiency and put extra strain on the unit.

How it’s affected:

  • Harder to heat water evenly
  • Higher energy bills
  • Noises during operation
  • Shorter unit lifespan

What you can do:

  • Flush your water heater once a year
  • Check for cloudy water or popping noises
  • Install a sediment filter on the incoming water line if buildup is frequent

2. Dishwasher

Dishwashers rely on clean water to spray and rinse dishes. When sediment builds up in the supply line or spray arms, performance drops. It can also clog the internal filter or damage the valve.

How it’s affected:

  • Dishes come out dirty or spotted
  • Water takes longer to enter the unit
  • Shorter appliance lifespan

What you can do:

  • Clean the dishwasher screen and spray arms every few months
  • Inspect the water inlet valve for buildup
  • Use a hose with a built-in sediment screen if needed

3. Washing Machine

Washing machines pull a lot of water quickly. Sediment can clog the inlet screens, wear out hoses, or collect inside the drum. This leads to longer cycles and can cause early wear.

How it’s affected:

  • Slower fill times
  • Hoses crack or leak from pressure changes
  • Visible grit on clothes or in the drum

What you can do:

  • Remove and clean inlet screens regularly
  • Inspect hoses for buildup or wear
  • Replace hoses every 3–5 years with high-quality, sediment-resistant lines

4. Refrigerator with Water Dispenser or Ice Maker

If your refrigerator uses water for drinking or ice, sediment can damage internal filters or clog the lines. Ice may taste odd, and water flow may slow down.

How it’s affected:

  • Ice cubes are cloudy or taste off
  • Water comes out slower or stops
  • Filters wear out faster

What you can do:

  • Replace the water filter on schedule (every 6 months or as needed)
  • Flush the water line if you notice taste or flow problems
  • Use a sediment filter before the refrigerator line for better protection

Keep It Simple: Monthly and Seasonal Checks

You don’t need a full inspection every week. But a few simple habits can keep your appliances safe from buildup:

Every month:

  • Wipe down inlet screens (washing machine, dishwasher)
  • Listen for new noises in your water heater

Every 6 months:

  • Replace refrigerator filters
  • Flush water heater if needed
  • Check for slow water flow or gritty water

Once a year:

  • Inspect and replace worn hoses
  • Schedule a professional flush if buildup is heavy

Final Note

Sediment buildup doesn’t cause problems overnight, but it builds slowly. The sooner you stay ahead of it, the longer your appliances will last and the better they’ll work.

If you’d like help inspecting your supply lines, replacing hoses, or installing a sediment filter, we’re here for that. Reliable care now prevents bigger problems later.
