Step 1: Stop Using Water Throughout the House
Every flush, shower, or load of laundry adds volume to a plumbing system that's already backing up somewhere downstream. Stop all water use immediately — every fixture, not just the one where you noticed the backup — until the blockage is located and cleared. This is the single most effective thing you can do to keep a bad situation from getting worse while you wait for help.
Step 2: Avoid Direct Contact With the Water
Wastewater carries bacteria, viruses, and other contaminants regardless of how clean it might look. Keep children and pets away from the affected area entirely, and avoid wading through standing water without protective gear (rubber boots and gloves at minimum) if you must be in the room.
If Sewage Contacts Skin or Open Wounds
Wash the area thoroughly with soap and water as soon as possible, and keep an eye out for signs of infection over the following days — when in doubt, a call to your doctor is a reasonable precaution.
Step 3: Ventilate If It's Safe To Do So
Opening windows in the affected area, if weather and safety allow, helps reduce sewer gas concentration in the room while you wait for a plumber. Running a bathroom or kitchen exhaust fan, if the outlet isn't near standing water, can also help — but don't use a standard vacuum or fan that could spread contaminated water or aerosolize bacteria.
Step 4: Call for a Camera Inspection, Not Just a Snake
Sewage backups are almost always caused by a blockage or structural break somewhere in the main sewer line, not the individual fixture where it happened to surface. Snaking alone might temporarily clear a symptom without addressing the actual cause, which means the backup often returns. A camera inspection lets us see exactly what's causing the blockage — root intrusion, a collapsed section, grease buildup, or a foreign object — before recommending a fix, so you're not paying for a repeat visit.
Why Sewage Backups Happen in Arlington Homes
Tree Root Intrusion
This is the single most common cause we see in Arlington's older, tree-lined neighborhoods. Roots from mature trees, planted decades before modern root-resistant PVC piping became standard, find their way into aging clay pipe joints seeking moisture, gradually restricting or blocking flow entirely.
Aging Pipe Materials
Original clay pipe and, in some mid-century Arlington homes, Orangeburg (a bitumen-impregnated fiber pipe used in the 1940s-1960s) both deteriorate and deform over time in ways that eventually restrict or block flow, independent of any specific clog.
Municipal System Surcharge
During major storms, backup can occasionally originate at the connection point with Arlington County's system rather than your own private lateral — a backwater valve is the standard protection against this specific scenario.
What Not to Flush
Wipes (even ones labeled 'flushable'), paper towels, and grease poured down any drain are common contributing causes we see repeatedly, gradually narrowing pipe capacity until a backup becomes inevitable.
After the Cleanup: What to Watch For
Once the blockage is cleared and the area is properly cleaned, keep an eye out for recurring slow drainage or gurgling in the weeks that follow — these can be early signs that the underlying cause (often root intrusion) wasn't fully resolved and is already beginning to regrow. If the same backup happens again within a few months despite clearing, that's a strong signal the pipe itself needs more than routine maintenance — trenchless lining or a targeted repair may be the more durable fix.

Frequently Asked Questions
What usually causes a sewer backup in older Arlington homes?
Tree root intrusion into clay or cast-iron laterals is the single most common cause in Arlington's older, established neighborhoods.
Is sewage backup covered by insurance?
Standard homeowners policies often exclude sewer backup unless you've added a specific rider — worth checking your policy before you need it.
Should I try to clean up sewage myself?
Basic containment (keeping people and pets away, stopping water use) is fine, but larger-scale cleanup involving contaminated water and materials is often better handled by a professional restoration service alongside the plumbing repair.
How do I know if I need a backwater valve?
If backups have happened more than once, or your home has experienced backup during major storms specifically, a backwater valve is worth discussing during the repair visit.
Can a sewage backup damage my home's foundation?
Not typically on its own, but prolonged moisture from an unaddressed backup can contribute to broader moisture issues worth having assessed if the situation was severe or prolonged.
How fast should I call after noticing a backup?
Immediately — every additional use of water in the house adds to what's already backing up, so time matters here more than with most plumbing issues.
