Well & City Water Sediment Filtration Services | Maryland, DC & Virginia

Whether you are dealing with abrasive sand from a private well or rust particles from aging municipal pipes, sediment is a physical threat to your home’s plumbing. National Water Service specializes in the installation and maintenance of high-capacity sediment filtration systems designed for the unique water profiles of Maryland, DC, and Northern Virginia.

Why Your Sediment Filter Matters

Sediment acts like sandpaper inside your pipes. A professional filter is the “first line of defense” that:

  • Saves Your Well Pump: Stops sand from grinding down pump impellers and rupturing pressure tank bladders.

  • Protects Appliances: Prevents grit from clogging sensitive valves in dishwashers and washing machines.

  • Stops Fixture “Choking”: Keeps showerheads and faucet aerators from losing pressure due to debris.

  • Pre-Treats Your Water: Protects expensive softeners and RO systems from heavy particles.

A blue and clear sediment filter is installed between two stainless steel ball valves on a wall. Text describes it as an easy-to-change, inexpensive filter with a $3.50 replacement cost. National Water Service logo is at the bottom left.

The Risks of Sediment in Your Water Supply

Sediment is made up of silt, sand, rust, or clay. These particles act like sandpaper inside your pipes and appliances, leading to:

  • Clogged Fixtures: Pebbles and grit blocking showerheads and faucet aerators.

  • Appliance Damage: Ruined valves in dishwashers, washing machines, and water heaters.

  • Well System Failure: For well owners, sediment is the leading cause of premature wear on well pumps and pressure tanks.

3 Professional Sediment Filter Installations to Choose From

We only install non-proprietary equipment, giving you the flexibility to choose the best technology for your specific usage and water quality.

Standard 3-Piece Housing (The Essential Barrier)

Ideal for standard residential use, these units are installed with most of our treatment systems to catch fine debris before it reaches your softeners.

  • Hardware: Available in 10-inch or 20-inch high-impact housings.

  • Filters: 5-micron sediment cartridges.

  • Valves: Standard CPVC shut-off valves included (Stainless Steel upgrades available).

  • Service: Every installation includes a free demonstration on how to change your filters.

"Big Blue" Jumbo Cartridge (High-Capacity Solutions)

The “Big Bubba” Jumbo filter is made of rugged, glass-reinforced polypropylene that will not chip, rust, or dent.

  • Usage: Best for high-demand homes or commercial applications removing sediment, turbidity, and chlorine.

  • No Waste: Conserves water because backwashing is not required.

  • Specs: Pleated or Depth cartridges (1 to 50 micron) with 3/4” or 1” professional installation.

Irrigation & Heavy-Duty Filtration

For properties with high-flow demands or dedicated irrigation systems, we offer three specialized configurations:

  • High-Flow Sediment Cartridges: Polyglass cartridges designed for indoor or outdoor installation. These support up to 30 GPM flow rates with minimal pressure drop.

  • Heavy-Duty Multi-Cartridge Systems: Rugged, glass-reinforced construction with built-in pressure gauges to monitor filter life. These units support massive residential and commercial demands from 50 to 150 GPM.

  • Maintenance-Free Automatic System: Our premium 10×54 Polyglass tank system. It uses a Metered Superclack Valve and battery backup to automatically flush sediment away, making it completely “hands-off” for the homeowner.

Professional Installation & System Sizing

A sediment filter is only effective if it matches your home’s flow rate.

  • Flow Calibration: We ensure your well water sediment filtration system supports your GPM (Gallons Per Minute) so you never experience a drop in shower pressure.

  • Bypass System: We install professional bypass valves so you can service your filter without shutting off your home’s main water supply.

  • Expert Integration: We place your filtration before your most expensive equipment to ensure your entire treatment suite stays clean.

Sediment Filtration FAQ

How do I know if I need a sediment filter?

Look for grit in the bottom of your toilet tanks, “surging” water pressure, or cloudy water. If you see “coffee grounds” in your sink, you likely have a sand or rust problem that needs immediate filtration.

We install the system at your home’s “point-of-entry”—after the city meter or well pump, but before your water heater and other treatment devices.

No. Sediment filters remove physical particles. To remove chemicals like chlorine, we pair these with Carbon Filtration. For bacteria, we recommend UV Sterilization.

Sediment filters work by trapping and removing particulate matter such as sand, silt, clay, and organic matter from water. They usually consist of a physical barrier (such as a mesh or a pleated material) that captures particles as water flows through it. The size of the particles that can be filtered out depends on the micron rating of the filter.

The size of the particles that can be filtered out depends on the micron rating of the filter.

Typically, sediment filters should be replaced every 3 to 6 months. However, heavy sediment or high water usage might require more frequent changes.

Look for decreased water pressure throughout the house. visible discoloration or cloudiness in the water, any unpleasant tastes or odors in the water, and look for a build-up of sediment in the filter housing or other parts of the plumbing system.

Sediment filters are primarily designed to remove particulate matter and do not typically remove bacteria or other microorganisms. For bacteria removal, a combination of filtration and disinfection methods, such as UV filters or chlorination, is required.
