Drains backing up at night. Stop the water, we clear the line.

When the lowest drain in the house starts filling on its own, every fixture upstream is feeding it and the clock is running. Royal Flush Affordable Plumbing clears main lines from the cleanout 24 hours a day Sunday to Friday, runs the line under load to prove it flows, and tells you what was in it, with the price agreed before the machine comes off the truck.

  • 24 hours, Sunday to Friday
  • $50 off drain and sewer cleaning
  • Price agreed before any work

Signs you need this

Six signs this is the main line, not one clogged sink.

A single slow drain can wait. These mean the whole house is backing up and water should stop now.

The ground-floor tub or shower is filling

With nobody using it. Wastewater from the whole house is coming up through the lowest fixture.

The toilet bubbles when the washer drains

Air and water pushed back through the nearest trap. The main line past both is blocked.

Every drain is slow at once

One slow drain is a trap. All of them is the line they share.

Water or sewage at the cleanout

The cap is weeping or the box is full. The line is blocked between there and the street.

A sewer smell in the yard or the house

Wastewater is escaping a blocked or broken line somewhere between the house and the city main.

It happened before

A line that backed up months ago and was cabled has the same cause still in it. This time it needs a camera.

What the emergency visit covers

Cleared from outside, tested under load, cause explained.

The main line is cleared from the exterior cleanout with a machine cable sized to the pipe, never through a toilet when there is any other access. The head is matched to what is in the line: a cutter for roots, a retriever for wipes and objects. Then every fixture in the house is run together and the flow watched at the cleanout. If it keeps up, the job is done. If the line is lined with grease or scale, the technician will say so and recommend jetting, which strips the pipe wall instead of boring through the blockage.

On a repeat backup, or where the cable met something that felt like a break, a camera goes in while the line is clear and shows roots, a belly, an offset or a collapse with the distance marked, so the next decision is made on video, not guesswork.

  • From the cleanout, with the right headRoots, wipes, grease and scale each need a different cutter. We bring them all.
  • Tested with every fixture runningA line that drains a trickle is not clear. We load it before we call it done.
  • Camera on repeatsThe second backup gets a camera so the cause is known and the third does not happen.

    Cleared, tested, explained

    The line is cleared, run under load, and you hear what was in it and whether it will be back.

What affects the price

What moves the price on an emergency backup.

Agreed before the machine comes out. These are the variables.

The access point

An exterior cleanout is the fastest route. No cleanout means a roof vent or a pulled toilet and more time; installing one makes the next time short.

What is in the line

Wipes and a fresh clog clear quickly. Roots and grease take longer and may need jetting to stay clear.

Cable or jetter

Cabling clears a blockage. Jetting cleans the whole wall and is the lasting fix for grease and roots.

A camera inspection

An option on first-time backups, strongly recommended on repeats. Priced separately so you choose.

The coupon

$50 off any drain or sewer cleaning, emergency calls included. Mention it when you call.

Emergency Drain Backup FAQs

Drain backup questions from Houston homeowners.

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
01Is a drain backup an emergency?
If sewage is coming up a drain, or more than one fixture is backing up, yes: wastewater from the whole house has nowhere to go but back into the lowest fixtures. One slow sink is not an emergency and can wait until morning.
02What should I do while I wait?
Stop using water: no flushing, laundry, dishwasher or showers. Move belongings off the floor near the lowest drain. Clear a path to the cleanout but do not open it, because it is under pressure. Open windows if there is a smell.
03Can you clear it through the toilet?
We clear main lines from the exterior cleanout wherever one exists. Going through the toilet means pulling it, a new wax ring and the risk of damaging an old flange, so it is a last resort when a house has no cleanout. In that case we recommend installing one.
04Why does it keep coming back?
Because cabling pushes through the blockage without removing its cause. Grease lining, roots, scale in cast iron, a belly or a broken section all return on a schedule. Jetting handles the first three; a repair handles the last two. A camera inspection tells you which you have.
05Could it be the city sewer and not my line?
Yes, if the city main is blocked or surcharged after heavy rain. A camera sent toward the street from a two-way cleanout shows where the problem is, and that footage is what the City of Houston asks for before it responds.
