If Your Sewer Backs Up In Port Chester, Do This First

Sewer water bubbling up in a tub or basement drain can stop your day cold. It is stressful, messy, and it can damage finishes fast. You can protect your home and health by taking a few focused steps right away. Here is a calm, local plan for Port Chester homeowners, plus who to call, what is yours to fix, and how to prevent it next time. Let’s dive in.

Do this first: quick steps

1. Stop using all water

• Turn off faucets and pause dishwashers and washing machines. Avoid flushing toilets. Continued use can make the backup worse.

2. Stay safe around electricity

• If water is near outlets or appliances, turn off power to the affected area at the breaker if you can do so safely. Do not touch breakers while standing in water.

3. Call Port Chester DPW now

• The Village maintains the public sanitary mains and pump stations. Call the Department of Public Works at 914-939-5207 so a crew can check the public main. Learn more on the Village’s Department of Public Works page.

4. Check the pattern of the backup

• One slow sink usually means a local clog. Multiple fixtures or a basement floor drain backing up usually points to a main line or private lateral issue. The NYC DEP explains this common workflow and responsibilities in its sewer backup guidance.

5. If DPW says the public main is clear, call a licensed plumber

• The problem is likely in the private sewer lateral that runs from your house to the main. Hire a Westchester County licensed plumber to inspect and clear the line. You can verify licenses using the County’s trades license lookup.

6. Protect people and pets

• Keep kids and pets away from affected areas. Wear rubber boots, gloves, eye protection, and a mask when cleaning. The CDC offers practical safety tips in its disaster safety and cleanup guidance.

Who handles what in Port Chester

Public main responsibilities

The Village of Port Chester is responsible for the public sanitary sewer mains and pump stations. If a backup is caused by a blockage in the public main, DPW will clear or repair it. Report suspected main problems to DPW at 914-939-5207 or visit the DPW page.

Private lateral responsibilities

Homeowners are generally responsible for the private sewer lateral from the house to the public connection. Port Chester requires inspections and compliance by qualified professionals in certain situations, including some property transfers. For details, see the Village’s building code provisions.

Health and cleanup basics

Safety and PPE

Sewage can contain bacteria and viruses. Wear rubber boots and gloves, eye protection, and at least an N95 when cleaning. Wash hands and any exposed skin after contact. Review CDC guidance on staying safe during cleanup.

Cleanup steps

• Remove standing water with pumps or wet vacs. Do not discharge sewage to storm drains.
• Clean hard surfaces with detergent, then disinfect. Discard porous items that cannot be fully disinfected.
• If materials stay wet for 24 to 48 hours, follow mold prevention guidance and consider professional remediation.
• Photograph all damage before disposal. FEMA explains why quick, documented cleanup matters in this fact sheet.

Document for insurance

Take dated photos and videos, keep receipts for cleanup and repairs, and save estimates and invoices. Separate damaged from undamaged items so an adjuster can review.

Insurance and coverage in New York

Many standard homeowners policies exclude sewer or sump backups unless you added a water backup endorsement. Contact your insurer promptly to report the loss and confirm coverage. The New York State Department of Financial Services outlines what is typically covered and what needs add-on coverage in its homeowner disaster FAQs.

Hiring help and permits

Find licensed plumbers

If DPW confirms the public main is clear, hire a Westchester County licensed plumber to inspect and clear your lateral. Confirm credentials using the County’s trades license lookup.

Permits and certification

Repair or replacement work on a sewer lateral may require permits and inspections. Start with the Village’s Citizen Access Permitting Portal for current steps. For transactions, Port Chester’s code requires certain inspections or certificates by a Westchester County licensed plumber, architect, or engineer. See the building code provisions for details.

Causes and prevention

Common local causes

Backups often come from wipes, grease, tree roots, or breaks and sags in older laterals. Port Chester has invested in a Downtown Sanitary Sewer Revitalization to reduce infiltration and inflow, which signals aging infrastructure challenges in some areas. Learn more about the Village’s revitalization project.

Prevent the next backup

• Do not flush wipes or pour grease down drains.
• Ask a licensed plumber about a backwater valve if your home is vulnerable.
• Schedule periodic camera inspections for older laterals.
• Make sure sump pumps discharge to a legal location.
• Consider a water backup endorsement if you do not already have one.
