The Town of Clifton has no public water system, so homes here run on private wells, and well sediment and pressure swings can wear a shower valve alongside ordinary age. Older homes in the historic district may also have valves past rebuilding. Call the number on this page to be connected with a local plumber in Clifton.

Signs it's the valve
- A drip from the head that never quite stops
- Flow and temperature that pulse during a shower
- Gritty, stiff handle movement
- Only the shower runs weak while sinks are normal
- Damp plaster or flooring next to the tub
If every fixture pulses, the well pump or pressure tank is the likelier cause. If only the shower misbehaves, look at the valve.
Clifton conditions
Clifton is a tiny National Historic District town in southwestern Fairfax County. The Town's FAQ notes there's no town water system, and new houses on vacant lots must have room for a water well and an onsite wastewater field. Fairfax County public sewer reaches only existing buildings that meet County guidelines. For shower valves, wells matter: fine sediment can lodge in cartridge ports and seats, and pressure tank cycling makes flow rise and fall. A sediment filter on the well line often protects new valve parts. The wider 20124 ZIP area outside town includes homes on Fairfax Water, so the setup varies by address.
Housing in the town is old, with a median build year around 1940 in a very small sample. That suggests some homes may still have early two- or three-handle valves, and old brass and supply piping that need care when parts are removed.
What shapes the cost
- Cartridge or stem repair versus a full valve replacement
- Older valves whose parts are hard to source
- Clearing sediment from the valve and lines
- Access through plaster, tile or a closet wall
- Permits: Fairfax County Land Development Services issues them, but the Town's Mayor or a designee signs building permit applications first, and interior-only work needs a letter from the Town clerk to LDS
When you call
You'll be connected with an independent plumber who serves Clifton. Mention that the house is on a well, whether other fixtures show the same problem and roughly how old the bathroom is. If the shower won't shut off, close the main valve, usually near the pressure tank. The plumber will check the valve and tell you whether the well system needs attention as well, so the new parts aren't clogged again within months.
