Most clogs are a nuisance. A main sewer line clog is a different story. When the pipe that carries all of your home’s wastewater to the city sewer is blocked, every drain in the house is affected, and sewage has nowhere to go but back up. Catching the warning signs early can save you from a messy and expensive cleanup.

What is the main sewer line?

Every sink, toilet, tub and appliance in your home drains into branch lines, and those branch lines all feed one larger pipe: the main sewer line. It runs from under the house, out through the yard, to the city connection near the street. Most homes have an outdoor cleanout, a capped pipe that gives plumbers direct access to the main line. If sewage is already coming up, call our emergency plumber in Hollywood right away — we answer 24/7.

7 warning signs of a main line clog

1. Several drains are slow at once. One slow sink is a local clog. Slow drains in different rooms point to the main line.
2. Gurgling toilets. A toilet that gurgles when the sink or washer drains means air is being pushed through a partially blocked line.
3. Water in the tub when you flush. The tub or shower is usually the lowest drain, so it is where backed-up water shows first.
4. Sewage odors. Smells from floor drains, the yard or the outdoor cleanout are a strong sign.
5. Water around the cleanout. Water or debris coming out of the cleanout cap means the line is full.
6. Soggy patches in the yard. Wet, green or sunken spots along the sewer path can mean a leak or root intrusion.
7. Backups after heavy rain. If drains slow down every time it storms, the line is likely already partially blocked.

Common causes in Hollywood homes

In South Florida, the most common causes are tree roots entering through joints in older clay or cast iron pipes, years of grease buildup from the kitchen, corroded cast iron that catches debris, and items like wipes and paper towels that should never be flushed. A sewer camera inspection shows which one you are dealing with, so you only pay for the fix you need.

How a main line clog is cleared

A technician accesses the line through the cleanout and clears it with a heavy-duty cable machine or a hydro jetter. Cabling opens the line quickly. Hydro jetting goes further, scouring grease and roots off the pipe walls so the line stays clear longer. Learn more about our sewer line cleaning service.

What not to do

• Do not keep flushing to “push it through.” You will only add more water to the backup.
• Do not pour chemical drain openers into a main line clog. They will not reach it, and they make the water hazardous.
• Do not rent a large drain machine without experience. They can injure the operator and damage old pipes.

Preventing the next one

If your home is older or surrounded by mature trees, an annual camera inspection and periodic jetting are far cheaper than an emergency backup. Keep grease out of the sink, flush only toilet paper, and know where your outdoor cleanout is.
