5-Star Rated

Water quality shows up everywhere in a house: scale on the shower glass, cloudy glassware, soap that will not lather, sediment rattling in the water heater, and fixtures that fail years early. ProStream Plumbing installs whole-home filtration and softening systems throughout Baltimore City, Baltimore County, Anne Arundel County and Howard County — specified from a test, not a sales script.

What We Install

  • Whole-home sediment and carbon filtration for particulate, chlorine taste and odor.
  • Ion-exchange water softeners sized to household demand and measured hardness.
  • Iron and sulfur treatment for private well systems.
  • Point-of-use drinking water filtration at the kitchen sink.
  • Scale-reduction protection ahead of tankless water heaters.
  • Filter changes, softener service and system repair on existing equipment.

Why Hard Water Costs You Money

Hardness minerals precipitate out as scale wherever water is heated or moves quickly. Inside a water heater, that scale becomes an insulating layer on the tank bottom or the heat exchanger, forcing more energy for the same hot water and shortening equipment life. Inside valves and fixtures, it seizes moving parts and causes the drips people accept as normal.

Treating the water is cheaper than replacing what untreated water destroys — particularly for households that just invested in a tankless water heater.

Iron and sediment loading in untreated water — what filtration is specified to remove.

Test First, Then Specify

Equipment should follow test results. Hardness, iron, pH, sediment load and household flow demand all change what the right system is. A softener does nothing for a taste complaint caused by chlorine, and a carbon filter does nothing for scale.

We would rather test and recommend a smaller system that solves your actual problem than install a large package you do not need.

Installed by a Plumber

Filtration equipment is plumbing. It needs correct placement relative to the service entry and water heater, proper bypass valves for service, appropriate drain connections for regeneration, and support so the unit is not hanging on the pipe. Those details are what separate a system that runs quietly for a decade from one that leaks in year two.
