4.7from 108 Google reviews Main sewer line cleaning in Houston

Every drain in the house backing up is a main line problem.

When the shower fills while the washer drains and the downstairs toilet gurgles, the blockage is in the main line that carries everything out of the house. Royal Flush Affordable Plumbing clears it from the cleanout, runs a camera when it keeps happening, and tells you honestly whether the pipe itself is failing.

Signs you need this

How to tell it is the main line and not one drain.

A single slow fixture is a branch clog. These signs mean the line everything shares.

More than one drain is slow

The kitchen, a bathroom and the laundry all slowing together share only the main line.

Water comes up the lowest drain

A shower, tub or floor drain on the ground floor is where a main line backup shows first.

Toilets gurgle when the washer drains

The washing machine dumps a lot of water fast. A narrowed main pushes air back through the nearest trap.

Water or sewage at the outside cleanout

If the cleanout cap is wet or pushed off, the blockage is between the cleanout and the city main.

Wet patches in the yard

A soft, green or smelly patch over the sewer run means the line is leaking as well as blocked.

It keeps coming back

A main that clogs every few months has roots, a belly or a break. Cleaning alone will not end it.

What we actually do

Cleared from the cleanout, then looked at.

We open the outside cleanout and run a main-line cable machine with a cutting head toward the city tap, then back toward the house if needed. For roots, grease or a line that has been cleaned before, hydro jetting cleans the full pipe wall instead of cutting a channel through the blockage.

If this is a repeat, we run a camera down the cleared line and show you the footage. A belly holding water, a cracked clay joint, or roots at a specific depth are the reasons main lines keep clogging, and the camera tells you which one you have before anyone talks about digging.

  • Main-line machine with cutting headsSized for 3 and 4 inch lines, with root-cutting and grease heads.
  • Jetting when cabling is not enoughRoots and grease come back after cabling. Jetting scours them off the wall.
  • Camera and locatorIf the line needs repair, we mark exactly where, so nobody digs up the whole yard.
How we fix it

A main line call, start to finish.

Main line backups are treated as urgent. Here is what happens when you call.

Sewage coming up a drain?

Stop using water in the house, including flushing. Every gallon has nowhere to go but up. Call and we will dispatch.

Call 281-612-1015
  1. 1
    Right away

    You tell us what is backing up

    Which drains, how fast, and whether there is water at the cleanout. We send a truck with a main-line machine and a camera.

  2. 2
    On arrival

    We find the cleanout

    Outside cleanouts are the fastest access. Older homes without one get a roof vent or a pulled toilet, and we tell you which.

  3. 3
    Before any work

    You get the price

    The cost to clear the main, upfront. If we recommend a camera inspection or jetting, that is a separate number you approve first.

  4. 4
    Same visit

    Cleared, tested, shown

    The line is cabled or jetted, every fixture is run together to confirm flow, and if a camera went down you see the footage.

What affects the price

What moves the price on a main line.

Upfront, before any work. These are the variables.

Access

An outside cleanout is quickest. Pulling a toilet or going through a roof vent takes longer and is priced that way.

What is blocking it

Paper and wipes clear with a cable. Roots and hardened grease need cutting heads or jetting.

Camera inspection

Optional on a first clog, strongly recommended on a repeat. It is the only way to see a belly or a break.

Cable or jetter

Jetting costs more than cabling and lasts much longer on roots and grease. We quote both when both make sense.

The coupon

$50 off any drain or sewer cleaning. Mention it when you book and show it at the time of service.

Main Line Drain Cleaning FAQs

Main line questions we hear every week.

Still not sure? Call and describe the problem. We’ll tell you honestly whether it’s a 20-minute fix or a job worth quoting.

Ask a plumber: 281-612-1015
01How do I know if it is the main line or just one drain?
If one fixture is slow, it is that fixture or its branch. If two or more fixtures in different rooms are slow or backing up, or the lowest drain in the house fills when water runs elsewhere, it is the main line.
02Where is my sewer cleanout?
Usually a capped pipe a few inches across near the foundation, often by the side of the house closest to the street, or by a bathroom wall. Older Houston homes sometimes have none, in which case we access the line another way and can install a cleanout for next time.
03Why does my main line keep clogging?
Roots growing in at a joint, a belly in the pipe where water and solids collect, grease that has hardened along the wall, or a cracked section catching debris. A camera inspection after cleaning shows which. Cleaning alone treats the symptom.
04Do you jet or cable a main line?
Both, depending on the blockage. Cabling cuts through paper and soft blockages quickly. Hydro jetting scours roots and grease off the pipe wall and keeps the line clear far longer. We tell you which we recommend and why.
05Is there a coupon for main line cleaning?
Yes. $50 off any drain or sewer cleaning service. Mention it when you book and show it at the time of service.
