What To Do During a Sewer Backup Emergency
Sewer backups are serious emergencies requiring immediate action to prevent health hazards and property damage. Here’s what to do immediately:
1. Stop using all water in the home
Do not flush toilets, run sinks, showers, dishwasher, or washing machine.
Any water use will worsen the backup.
2. Stop adding water to the drainage system
Do not flush toilets, run sinks, showers, washing machines, or dishwashers.
If an unrelated supply-side leak is also occurring, shut off the appropriate fixture valve or main water supply if you can do so safely.
3. Call emergency plumber: (508) 474-7481
Sewer backups require professional equipment and expertise. We respond
24/7 across MetroWest with sewer cleaning equipment.
4. Keep people and pets away from sewage
Raw sewage contains dangerous bacteria and pathogens. Keep everyone
away from affected areas until professional cleanup.
5. Do not attempt DIY clearing
Main sewer line clogs require professional equipment like sewer snakes
and hydro-jetting. DIY attempts often worsen the problem.
6. Document the damage and check your insurance coverage
Take photos of sewage backup and affected areas before cleanup when it is safe to do so.
Standard homeowners policies generally do not cover sewer or drain backups unless specific backup coverage or an endorsement has been added.
Check your policy or contact your insurer as soon as possible.
Sewer Backup in Your Basement? Do This First
Sewage coming up through a basement floor drain, toilet, shower, or utility sink is one of the clearest signs that wastewater is no longer flowing properly away from the property.
If you have a sewer backup in your basement, stop using water immediately. Do not repeatedly flush toilets or run fixtures to see whether the problem clears itself. Every additional gallon entering a restricted drain or sewer line can increase the amount of wastewater backing into the lowest part of the home.
Keep children and pets away from the affected area and avoid direct contact with sewage. Raw wastewater can contain bacteria, viruses, and other pathogens. Massachusetts public-health guidance specifically warns homeowners about health risks associated with sewage backups.
If several fixtures are affected at the same time, the problem is more likely to involve the main building drain, sewer service line, or wastewater system rather than one isolated fixture.
What Causes Sewer Backups?
Sewer backups can happen suddenly due to various causes. Understanding what causes backups helps identify the problem and prevent future issues:
Tree Root Intrusion
Roots can enter damaged joints or cracks and gradually restrict flow.
Grease, Wipes & Debris
Grease hardens inside drain lines, while wipes and foreign objects can catch on rough or damaged pipe surfaces.
Broken, Offset or Collapsed Sewer Lines
A line can crack, separate, settle, or partially collapse and repeatedly trap waste.
Heavy Rain & Sewer System Overload
For properties connected to municipal sanitary sewer, groundwater and stormwater entering damaged sewer infrastructure can reduce capacity during major storms. MassDEP specifically notes that infiltration and inflow can contribute to wastewater backups into homes and businesses.
Private Septic / Wastewater Problems
Not every MetroWest property connects to municipal sewer. Where a septic system is present, backups may originate farther downstream than the home’s plumbing and may require a septic professional once the plumbing side has been diagnosed.
Professional sewer backup service includes main line cleaning, camera inspection to identify the cause, and repairs if needed. Our licensed plumbers in Framingham, Natick, Marlborough, Wellesley, and Ashland respond to sewer emergencies 24/7 with equipment to clear blockages and restore proper sewer flow.
Multiple Drain Backups
Warning Signs of a Main Sewer Line Backup
Raw sewage or dirty water backing up through basement floor drains or lowest toilet — immediate sign of main line blockage.
Multiple drains backing up simultaneously — toilets, sinks, tubs — indicates main sewer line clog rather than isolated drain problem.
Toilets gurgling when other fixtures drain, or water level fluctuating — air trapped in sewer line pushing back through system.
Strong sewage smells from drains or yard near sewer line — sign of backup, crack in sewer line, or ventilation problem.
Why MetroWest Residents Call Us for Sewer Backup Emergencies

Clogged Drain or Main Sewer Backup?
One clogged sink does not necessarily mean you have a sewer backup.
A single slow fixture often points to a localized drain problem. But when toilets, sinks, tubs, showers, or basement drains begin backing up together, the restriction may be farther downstream in the main building drain or sewer line.
If only one fixture is affected, see our Drain Cleaning service.
Signs that may indicate a main sewer line problem include:
- Multiple fixtures draining slowly at the same time
- Water rising in a shower or tub when a toilet is flushed
- Basement floor drains backing up
- Gurgling toilets
- Sewage odors from several drains
- Wastewater appearing at the lowest fixture in the home
- A backup that returns shortly after drain cleaning
Sewer Backup or Municipal Sewer Problem?
If several nearby properties appear to be affected or sewage seems to be coming from a public sewer problem rather than your private plumbing, contact your local sewer authority as well.
A private sewer backup usually involves the building drain or service line serving an individual property. A sanitary sewer overflow involves the public sewer system.

Sewer Backup: What You Need to Know
Common questions about sewer backup repair in MetroWest Massachusetts.
How much does sewer backup repair cost?
Costs vary depending on cause and severity of backup. Simple main line cleaning is less expensive than repairs for broken pipes or tree root removal. We provide upfront estimates before beginning work and can explain all options.
Does homeowners insurance cover sewer backups?
Most standard policies cover sudden sewer backups, but coverage varies. Some require sewer backup endorsement. Document all damage with photos immediately and contact your insurance company. We can provide documentation for claims.
How do you clear main sewer line clogs?
We use professional equipment including industrial drain snakes to break through blockages, hydro-jetting to completely clear pipes and remove buildup, and video camera inspection to locate and diagnose the exact cause of backup.
Can tree roots cause sewer backups?
Yes, tree roots are a leading cause of sewer backups in MetroWest. Roots penetrate sewer lines through tiny cracks seeking water, then grow inside pipes creating blockages. We can clear roots and recommend solutions to prevent future intrusion.
How can I prevent sewer backups?
Schedule periodic main line cleaning, especially for older homes or homes with trees near sewer lines. Avoid flushing wipes, grease, or foreign objects. Install backwater valve if in flood-prone area. Regular maintenance prevents most backups.
Is sewage backup dangerous?
Yes. Raw sewage contains dangerous bacteria, viruses, and pathogens that create serious health risks. Keep people and pets away from sewage. Professional cleanup is essential. Our team responds immediately to minimize health hazards and property damage.
What should I do if sewer backs up into my basement?
Stop using water immediately. Do not flush toilets, run sinks, take showers, use the dishwasher, or run the washing machine, because additional wastewater may make the backup worse. Keep children and pets away from the affected area and avoid direct contact with sewage. If possible, move valuables away from contaminated water without putting yourself at risk. Then call for emergency plumbing service. A basement sewer backup may be caused by a blocked main drain, damaged sewer line, root intrusion, heavy buildup, or another restriction farther downstream.
Why are multiple drains backing up at once?
When several fixtures begin backing up at the same time, the problem is often farther down the drainage system rather than at one individual sink, toilet, or shower.
Warning signs may include toilets gurgling, water rising in a bathtub when another fixture is used, basement drains overflowing, or several drains becoming slow at once.
A blockage in the main building drain or sewer line can affect multiple fixtures throughout the property. Stop adding unnecessary water to the system and call for diagnosis before the backup spreads.
Can heavy rain cause a sewer backup?
Yes, in some situations.
Properties connected to municipal sewer systems can experience backups when heavy rain contributes to excessive groundwater or stormwater entering the sanitary sewer system. This is often referred to as infiltration and inflow, or I&I.
When the public system becomes overloaded, wastewater may have difficulty flowing away from some properties. However, heavy rain does not automatically mean the municipal sewer is responsible. A private blockage, damaged sewer line, basement drain problem, or other plumbing failure may produce similar symptoms.
A plumber can help determine whether the problem appears to be within your property’s plumbing or farther downstream.
Do I need sewer cleaning, sewer repair, or sewer replacement?
It depends on what is causing the backup.
If grease, debris, wipes, roots, or another obstruction is restricting an otherwise structurally sound line, sewer cleaning may restore normal flow. Access through a sewer cleanout can often make diagnosis and clearing easier.
If backups keep returning, sewer scope services or a camera inspection can help identify cracks, root intrusion, separated joints, offsets, corrosion, or collapsed sections inside the pipe.
When structural damage is found, sewer line repair may be enough if only part of the line has failed. More extensive deterioration or collapse may require sewer replacement.
If you are searching for sewer line repair near me or sewer repair near me because wastewater is already backing into the property, call before continuing to use the plumbing system.
