The Town of Clifton has no town water system, and homes in town rely on private wells, so a softener decision starts with a test of your own well. Some homes in the wider Clifton area may be on Fairfax Water instead. Call the number on this page to be connected with a local plumber in Clifton.

Signs your well water needs treatment
- White scale on fixtures, kettles and shower glass
- Orange or brown stains in sinks and toilets, a sign of iron
- Black specks or staining that can point to manganese
- Soap that won't lather and laundry that comes out stiff
- A softener that clogs or loses capacity quickly
Local conditions in Clifton
The Town of Clifton's FAQ says there is no town water system and new houses on vacant lots must have room for a water well and an onsite wastewater field. Public sewer is available only to existing buildings that meet Fairfax County's guidelines, so many homes send their wastewater to a private onsite system. The median home in town dates to about 1940, among the oldest housing in Northern Virginia, so piping near the well and pressure tank can be a mix of materials and ages.
Groundwater differs from property to property. A lab test for hardness, iron, manganese and pH tells the plumber what to install. In some homes a softener alone is enough; in others an iron filter or pH correction belongs in front of it. If your property in the wider 20124 area is on Fairfax Water, its plant analyses show hardness of about 70 to 185 mg/L, and a simple tap test is enough.
For homes with a private onsite system, keep regeneration water to a minimum with a metered, high-efficiency softener. Talk with whoever services your onsite system about where the discharge goes.
What affects the cost
- Water test results and any filters needed ahead of the softener
- Space near the pressure tank for several units
- Drain routing and whether it goes to an onsite system
- Older piping or valves near the well tank that need replacing
- Capacity for the household's daily use
- Removing outdated equipment
What happens when you call
The number on this page is a free referral line, not a plumbing company. It connects you with an independent plumber who works in Clifton. Share any recent well test, the size of the household, and what equipment is already in place. For permits, building permit applications come from Fairfax County Land Development Services, but the Mayor or a designee must sign them first; for interior-only work, the Town clerk can provide a letter to the County.
