A plumbing inspection in Clifton covers the well pump and pressure tank, supply and drain piping, fixtures, shutoffs, water heater and propane connections, plus the line to a private onsite wastewater system where there is one. With no town water system and very old housing, it's a different visit from a typical suburban one. Call the number on this page to be connected with a local plumber in Clifton.

Reasons to book one in Clifton
- You're buying an older house in or near the historic district
- Pressure drops, or the well pump cycles on and off rapidly
- Water has started to look, smell or taste different
- Drains are slow, or the yard is soggy near the drain field
- Propane appliances that nobody has looked at in years
What's different about Clifton
Clifton is a tiny town chartered in 1902, a National Historic District since 1984, with wooded single-family lots and equestrian land to the north. The median home dates to about 1940, which is old enough that a house can still have galvanized or mixed supply piping, original drain lines and plenty of later add-ons. Freezing nights are hard on pipes in crawlspaces and older exterior walls, so the plumber will look at insulation and at outdoor spigots too.
The Town has no water system. Homes rely on private wells, and new houses on vacant lots must have room for a well and an onsite wastewater field. Public sewer is available only to existing buildings that meet Fairfax County's guidelines, with County approval to connect. So for most houses, the plumber evaluates the well pump controls, pressure tank, pressure switch and any treatment equipment, and the drain line out to the onsite system. Water testing and pumping the system are separate services, but the plumber's notes help you know what to order.
No gas utility serves the Town, and homes use their own propane. The plumber can check appliance connectors and venting. If you smell gas, leave the building, call 911, then your propane supplier. Outside town limits, the wider 20124 ZIP covers a larger area where water and sewer vary by address.
What shapes the cost
- Well equipment and water treatment to evaluate
- Age of the house and how much piping is reachable
- A camera run of the drain line
- Number of propane appliances
What happens when you call
You're connected with an independent local plumber who works around Clifton. Give the address, the build year and whether the house has a well and an onsite system. If repairs follow, Fairfax County Land Development Services issues permits, after the Town's Mayor or designee signs the application; for interior-only work, the Town clerk can send a letter to LDS instead. Ask for findings in writing so you can sort urgent items from longer-term ones.
