Emergency Sewage Backup Service
A sewage backup happens when wastewater flows back into your home instead of out to the sewer, usually through floor drains, toilets, or tubs. It is a health hazard that needs immediate professional attention. FlowFast connects you with an independent local plumber who can stop the backup, clear the blockage, and get your drains flowing the right direction again.

View all Emergency servicesFew plumbing problems are as urgent — or as unpleasant — as sewage coming back up through your drains. A backup usually means the main sewer line is blocked or damaged, so every flush and every load of laundry has nowhere to go but back into the lowest fixtures in the house. Raw sewage carries bacteria and pathogens, so standing wastewater in tubs, showers, or floor drains is a genuine health risk, especially for children, pets, and anyone with a weakened immune system. Do not wait until the damage spreads.
If you see or smell sewage backing up, stop using all water in the house: no flushing, no laundry, no dishwashing. Then get help fast. FlowFast connects you with an independent local plumber who can locate the blockage with a camera inspection, clear it with professional equipment, and advise on whether the line itself is damaged. Avoid the contaminated area and keep pets away until it is cleaned up. If you are unsure what you are dealing with, describing the symptoms when you reach out helps the pro arrive prepared.
Warning signs
Signs you need this service
- Multiple drains backing up at once, such as a toilet gurgling when the washing machine drains or the tub filling when you flush.
- Sewage or foul-smelling water rising in floor drains, basement showers, or the lowest fixtures in the house. Ensuring the problem is fully resolved.
- A strong sewage odor coming from drains, especially after heavy rain or when neighbors are having similar problems. And prompt attention prevents costlier damage.
- Toilets that will not flush properly while sinks also drain slowly, which points to a blockage in the shared main line.
What to expect
The process, step by step
The pro confirms the backup, checks whether the problem is in your line or the municipal side, and stops further use of water.
A camera is run through the main line to find the blockage, which may be roots, grease, a collapsed section, or a foreign object.
The blockage is cleared with professional equipment such as an auger or hydro jetter, and flow is restored and tested.
They report what caused the backup and recommend next steps, from root treatment to line repair if the pipe is damaged.
Prevention
How to avoid this problem
- Never flush wipes, even ones labeled flushable, along with paper towels, hygiene products, or cooking grease. And do not skip it.
- Have the main sewer line camera-inspected every couple of years if your home has mature trees near the line.
- Install a backwater valve if your area is prone to backups during heavy rain, so sewage cannot flow back in.
