Commercial Plumbing in Sterling, VA

Signs to watch for

• Backflow devices on irrigation or fire lines that are past their yearly test
• Restroom fixtures in a warehouse or flex building that keep clogging
• Older shutoff valves that won't close fully during a repair
• A water heater that runs out halfway through a shift
• Drain lines that back up after heavy rain
• Pipes in loading docks or unheated areas that froze last winter

Local conditions in Sterling

Sterling started with the early-1960s Sterling Park development on former farmland, and about 43% of homes in ZIP 20164 predate 1980, many from the 1960s through the 1980s. That makes it one of the older parts of Loudoun County, and the shops and small commercial buildings around Sterling Park and Sterling Boulevard often have original drains and valves.

Loudoun Water serves Sterling's public water and sewer. Its Central System draws mainly on the Potomac River, with Goose Creek water as needed, and uses chloramine at both of its treatment sources. The utility says its system contains no lead service lines. Its cross-connection program covers non-potable connections such as irrigation and pools, and backflow preventers must be tested every year by a certified tester. Customer Relations is 571-291-7880; after-hours emergencies go to 571-291-7878.

Permits come from Loudoun County Building and Development. Plumbing, gas and mechanical trade permits are filed as sub-records of a parent building permit through LandMARC or in person in Leesburg. Gas service in Loudoun is split between Columbia Gas and Washington Gas, with propane where neither reaches, so check the bill. If anyone smells gas, get everyone outside, then call 911 and the gas company or propane supplier.

What affects cost

• Age and condition of drain and supply piping
• Size of the space, from a small shop to a large flex building
• Whether a backflow device needs repair before it passes
• Access in finished offices versus open warehouse ceilings
• Permit steps with Loudoun County
• After-hours scheduling around operations
