Sewer Line Cleanouts
A sewer cleanout is a capped fitting on the main line, usually a few inches of pipe sticking up near the foundation or at the property line. It exists so a plumber can get a main line machine straight into the lateral without going through the house. When the main is blocked, that access is the difference between clearing the line from the yard in an hour and pulling a toilet or working from the roof vent, which is slower, messier and harder on the pipe.
Plenty of homes in the older parts of Austin and San Antonio were built before cleanouts were standard, and plenty more have one buried under a flower bed or paved over by a patio. Radiant clears main lines from any access that exists, and where there is none, we install a two-way cleanout so the next backup, if there is one, is a quick job instead of a project.
The clearing itself is done with a main line machine and cutter heads sized to the pipe, which handles roots, wipes, grease and the sediment that collects in a belly. If a line has been cleared before, we follow up with a camera so you know whether you are dealing with buildup that jetting can finish, or a broken pipe that needs a repair. Either way, the no-backup guarantee is in force: if the line backs up or slows after we clear it, we check it at no charge and make it right if it is related to our work.
What to Watch For
These are house-wide symptoms. If you see one, stop running water and call.
One clogged sink is a sink problem. A sink, a tub and a toilet all misbehaving is a main line problem, because it is the only pipe they share.
A ground-floor shower or tub fills with water when an upstairs toilet flushes. Wastewater takes the lowest exit it can find.
Air pushed back through the traps because the line downstream is nearly closed. Usually a day or two ahead of a full backup.
The line is blocked between the cleanout and the street, and the cap is the pressure relief. Do not run more water.
Sewage leaking from a broken or separated section of the lateral. Often paired with a patch of grass that is greener than the rest.
Roots and breaks do not clear themselves. A second backup within a year means the line needs a camera, not just another cable.
What We Do
Clearing the line is the first step. Finding out why it blocked is the one that keeps you from calling again.
How It Works
Quick to clear, clear about what comes next.
Tell us what is backing up. Keep everyone off the taps and toilets until we get there, and pull the cleanout cap if you can reach it safely.
The plumber locates the cleanout, or the best alternative if there is none, and confirms the blockage is in the main line.
For the clearing, and separately for a camera or a new cleanout if we recommend one. No pressure on either.
The line is opened, every fixture is flow-tested, and you hear what we pulled out and what it means for the pipe.

It is a capped pipe fitting that gives direct access to your main sewer line. On most Central Texas homes it is a white or black plastic cap, three or four inches across, sticking up a few inches from the ground near an exterior wall, most often on the side of the house closest to the street or on the bathroom side. Some homes have a second one near the property line where the lateral meets the city main. Older homes may have a brass or cast iron cap, and some have the cleanout inside, in a garage, utility room or under a bathroom sink. If you cannot find one at all, the house may simply not have one, which was common in older construction. We can locate a buried one or install a new one.
We can still clear the main line, but it takes longer and it is harder on your fixtures. Without a cleanout, the options are pulling a toilet and running the machine through the closet flange, or going in from a roof vent. Both work; both add time and mess to what should be a straightforward job. The better answer for a home that has backed up once and will likely back up again is to install a two-way cleanout on the lateral outside. It is a modest excavation near the foundation, a fitting spliced into the line, and a cap at grade. From then on, every clearing, jetting or camera inspection happens from the yard. We will price it as a separate line so you can decide.
Because the main line is blocked somewhere between that cleanout and the street, and the cleanout is the lowest open point upstream of the blockage. Every gallon you send down is backing up until it finds that cap, which is actually doing you a favor: the alternative exit is a tub or a floor drain inside the house. Stop running water, keep kids and pets away from the wet area, and call. The blockage is usually roots, a wad of wipes or a collapsed section of old clay or cast iron pipe, and clearing from that same cleanout is the fastest way to open it. If it happens more than once, the line needs a camera to find out why.
Not for most homes with a sound line. A newer PVC lateral with no root problems can go decades without attention. The homes that benefit from scheduled main line service are the ones with a known issue we are managing rather than fixing: an older clay or cast iron lateral with root intrusion at the joints, a line with a belly that collects sediment, or a house where the last two backups came at the worst possible times. For those, an annual clearing or jetting ahead of the holidays is cheap insurance. The honest long-term answer for a root-prone line is a repair or replacement, and we will tell you when the maintenance is costing more than the fix would.
