What the symptoms say about where the line is blocked
Start with what you see and where. The answer tells you how fast to act and how far the cleaning has to reach.
| What you see | Likely blockage | First step | Can it wait? |
|---|---|---|---|
| Basement tub or floor drain bubbles or rises | Main line | Stop water use and call | No |
| Several toilets slow together | Main line | Stop water use and call | No |
| Only one upstairs sink is slow | Branch line | Try a plunger, then book | Usually same day |
| Gurgling in a toilet when the washer drains | Partial main line clog | Reduce laundry, book soon | Same day |
| Wet patch or odor in the yard over the line | Blockage or damage outdoors | Stop water use and call | No |
| Septic home with backup and slow drains | House line or full tank | Call, avoid chemicals | No |
A plunger works on a toilet or sink clog. It will not move a main line blockage.
Sewer backups: what is happening and what to do first
A sewer backup happens when wastewater has nowhere to go and returns through the lowest openings in the house. That is usually a basement tub, shower or floor drain. It often shows up first when the washing machine empties, because that is a large, fast discharge.
Callers often describe it the same way: a toilet bowl clogged on one floor, then water in the kitchen or the basement bathroom. That pattern means the blockage sits past the point where those lines meet, in the main.
Stop using water in the house. Do not enter standing sewage barefoot, and do not use a household vacuum on it. We handle the line itself, and once water is flowing again you can call a cleanup company for the floors and drywall.
When a sewer backup is an emergency
Treat it as an emergency when sewage is entering living space, when the water is spreading toward finished flooring or electrical equipment, or when several fixtures stop at once. Our 24/7 dispatch handles those calls at night, on weekends and on holidays.
A single slow fixture that is not flooding can be booked as a same-day appointment when available. In all cases, keep the washer and dishwasher off, photograph the water line on belongings and walls, and keep children and pets away. Your insurer or landlord will ask what the backup reached.
Sewage in the basement?
Call the 24/7 line now. A licensed plumber can start clearing the main as soon as the truck arrives.
How we clear a main line
We start at the cleanout, which is a capped pipe usually found outside the house or in the basement near the main stack. If there is none, we pull a toilet or work through a roof vent, and we recommend adding a cleanout afterward so future service stays simple.
A heavy cable with a cutting head opens most root and paper blockages. Grease and mineral coating on the wall call for hydro jetting after the cable has opened a path. Then the camera goes in to confirm the line is clear and to show anything the cable left behind.
That last step matters. A line that cleared but shows a cracked joint or a low spot that holds water will back up again, and the fix then belongs to sewer line repair.
Why Wildwood main lines back up
Roots lead the list. The city's Master Plan describes Wildwood as the rolling and hilly woodlands of the Ozark foothills, and mature trees often stand within reach of a lateral. Census ACS data for 2020 to 2024 show a median build year of 1992 and about 42.8 percent of homes built before 1990, so many trees have had decades to reach a joint.
Rain is the second pattern. During the November 4 to 6, 2024 storm, the National Weather Service logged 8.34 inches of rain in nearby Ballwin. After a storm like that, check your cleanout and basement floor drain, and tell the plumber whether the backup began during the rain, since that points to a different problem than a plain clog.
Older areas along Old Manchester Road, such as Grover and Pond, and homes of any age with grease-heavy kitchens add their own causes. We read the camera footage rather than assume.
Not on MSD sewer? Cleaning a septic or package plant line
Many Wildwood homes, especially west of Highway 109, drain to a private septic tank or a subdivision package plant, while others connect to MSD Project Clear. We clear the line between the house and the tank or the sewer main. Backups that keep returning on a private system can mean a full tank, so we say so.
Avoid caustic drain products on those systems. Lye and acid can harm the bacteria that digest solids in the tank, and the dose that passes through reaches a field or plant built for ordinary waste.
Sewer drain cleaning, backwater valves and prevention
Sewer drain cleaning on a schedule is the cheap form of prevention for a line that has clogged before. Landlords and busy households often choose it every year or two. If you have a repeat problem, ask us about a camera look to find the cause.
A backwater valve is a plumbing fitting that closes if flow reverses in the line. It does not unclog anything, and it needs correct placement and access for maintenance. Ask MSD whether any backup prevention program applies to your address before you buy one.
For a drain that is slow in only one fixture, our drain cleaning service is the better fit.
Storm drains and driveway culverts are a separate system
Yard drains, downspout lines and driveway culverts carry rainwater, not household waste, and they should never connect to the sewer line. They clog with leaves, silt and mulch, and clearing them is mostly debris removal. If a roadside culvert is backing up, ask whether the road authority or you maintain it before paying for work.
If water stands in a yard drain while the sewer line is flowing, the problem is in the storm system, and a cable or a jet works there too. Tell us which line is which when you call.
What a main line clearing visit includes
- 1
Find the cleanout and read the symptoms.
We ask which fixtures failed first and open the line closest to the blockage.
- 2
Cut through the blockage.
A cable with a cutting head opens the path, and you see what comes out, such as roots, paper or grease.
- 3
Scour if the wall is coated.
If the line is coated, we follow with jetting to remove the layer that would rebuild the blockage.
- 4
Camera the line and flush the fixtures.
We confirm the flow, show any damage, and tell you whether a repair is next.
What affects the price of sewer line cleaning
Main line work is priced by the line, not the symptom. You get a clear price before work starts.
A short main to the street is quicker than a long line to a distant tank or manhole.
Paper and grease clear quickly, and dense roots need slower cutting.
A working cleanout saves time, while pulling a toilet adds it.
Each adds equipment and time, and you decide which to include.
After-hours dispatch costs differently from a same-day daytime visit.
Insurance often excludes backups from a blocked line unless you carry a water backup endorsement. If sewage damaged floors or belongings, check your policy and photograph everything. Your policy decides.
To price your line, call our 24/7 number and describe where the water appeared.

Questions we hear in Wildwood, MO
Yes. Our 24/7 dispatch covers sewer backups at any hour, including weekends and holidays. Call the emergency line and tell the dispatcher where the water is coming up.
A slow drain with no water on the floor can usually be booked as a same-day appointment when available.
The usual causes are roots entering joints, grease and paper buildup, a belly where water pools, and a damaged pipe. Heavy rain adds stress to the system. A camera shows which one applies.
No. A plunger moves a toilet or sink clog but not a main line blockage, and chemicals sit above the clog and splash during the work. On a septic system, caustic products can also harm the tank bacteria.
Sometimes. A clear camera view means the cause is probably gone. A cracked joint, a low spot or live roots can bring it back, which is why we camera the line and tell you if jetting or a repair is next.
We can clear yard drains and downspout lines, which are separate from the sewer. Roadside culverts may belong to the road authority, so ask who maintains yours before we start.
Drain cleaning usually means a sink, tub or branch line. Sewer line cleaning means the main that serves the whole house, which needs larger equipment and a camera afterward.
