What is trenchless sewer repair and when is it an option?
You have been told the sewer line may need replacing, and you want to know if that means digging it all up. Trenchless repair avoids that. The plumber works from one or two small access pits, or from an existing cleanout, and either lines the old pipe from the inside or pulls a new pipe through the old path.
It is an option when the line is cracked, offset at a joint, or split by root intrusion at a clay joint, but still runs as one continuous pipe. Cast iron choked with scale can sometimes be lined too, after the scale is cleared. That usually means hydro jetting first, then a camera inspection to confirm the pipe condition.
It is not an option when the pipe has collapsed, when a bellied line holds water and the slope has to be corrected, or when sections are crushed or missing. A liner follows the old path, so a sag stays a sag. Those jobs need open excavation.
The camera inspection decides it. If the main line clogs again after every Drain Cleaning visit, the pipe may be failing, not just dirty.
Cost depends on how deep and how long the line is, how many access points are needed, the materials used, how much has to be opened up or removed above it, and any permit or code requirement.

Before any lining starts, ask the plumber to confirm where every side connection joins the main. Branches such as a second bathroom or a laundry line have to be reopened from the inside once the liner sets, and the camera run afterwards should show each one open. Tell the plumber about earlier backups, the age of the house and any past repairs, because older homes often have clay, cast iron and fiber pipe in the same run, and the liner has to bond to each. The finished pipe is slightly narrower inside, but its surface is smooth, so flow usually improves. Plan around laundry and showers while the liner cures, since the line cannot be used until it has set. Ask for the recording of the finished pipe and keep it with your house papers. It helps if you sell the home, and it shows the next plumber exactly what was installed and where it runs.
Can a drain under a concrete slab be cleared without breaking the floor?
Usually, yes. Clearing a blockage and repairing a broken pipe are two different jobs, and only the second one needs the floor opened.
In a slab-on-grade house the drain lines run inside or beneath the concrete. There is no crawlspace to inspect, so symptoms are the only evidence you have. A cable or a hydro jetter still reaches the line through a cleanout or through a pulled toilet. Grease build-up on the pipe wall, roots in a joint and scale in cast iron can all be cleared that way.
What does need the floor opened is a cracked, collapsed or bellied section under the slab. A bellied line holds water and collects waste however often it is cleared. In older housing stock where clay or cast iron was the standard, failed sections are more likely.
A camera inspection with a locator pinpoints the fault. The plumber finds the exact spot and marks it on the floor before anything is cut, which keeps the opening small. What the job involves is driven by access, the materials, how much concrete must be opened and removed, and any permit or code requirement. Opening a slab often brings one in.
Safe homeowner check: note whether one fixture is slow or every drain is affected. A single slow fixture is usually a cable job on a branch line. Every drain backing up points to the main line or the sewer lateral.
Stop running water and call now if the whole house is backing up. Report water staining or a warm, damp patch on the floor, because it can mean a leak under the slab.

A spot repair under a slab is more disruption than most people picture. The plumber breaks out a section of concrete, digs down to the pipe, replaces the damaged length, and the floor is patched. Dust, noise and a few days without some fixtures are normal. Furniture and flooring over the area must be moved first, and tile or a finished floor may not match after patching.
For longer runs of damage, some plumbers can line the pipe from inside, or route a new line overhead or outside the house, which avoids cutting the slab. Whether either suits your pipe depends on its condition and on local code.
Ask to see the camera footage and the locator mark on the floor before any cutting begins. Mention in-floor heating, radiant tubing or a post-tension slab if you have one. Cutting into those without knowing is dangerous, so the plumber needs to hear about them before a saw comes out.
Water shows up around the base of the toilet after flushing. Is that the drain or the seal?
"There is water around the base of my toilet after I flush." Water at the floor can come from three places, and only one of them is the drain.
The most common cause is a failed seal. A toilet sits on a wax ring or a rubber seal that joins it to the flange, the fitting on the floor drain. If the ring is crushed or the toilet rocks, water escapes at the base during the flush. A loose bolt, a cracked flange or a flange set too low can do the same.
A drain problem is the other case. If the toilet is partly blocked, the flush water slows and rises, and it can push out at a weak seal. Grease build-up, a bellied line holding water, or root intrusion at a clay joint can all do this.
Here is the test. If only this toilet leaks and every other drain runs clean, think seal or flange. If the bowl drains slowly, gurgles, or the tub and floor drain are also slow, think drain. If every drain in the house is backing up, the main line or sewer lateral is involved.
Safe homeowner check: Flush and watch where the first drop appears. Press the toilet by hand to see if it rocks. Check the supply line and shutoff valve for drips. Look at the bowl: does it drain quickly or slowly? Do not over-tighten the closet bolts, because porcelain cracks.
Stop running water and call now if the water on the floor smells of sewage, the toilet will not drain or the bowl rises, other fixtures are backing up, or water is coming through a ceiling below.
A cable machine is enough for a toilet blocked by a clog close to the bowl. A seal or flange job is a reset, not a drain job: the toilet is lifted and a new ring and fittings go in. If the drain keeps slowing, a camera inspection can show roots or a belly, and hydro jetting is used for grease or scale coating the pipe wall.

Ask the plumber to say whether the problem was the seal, the flange or the drain, and what they checked. Ask if the subfloor is wet or soft, since that can widen the work. Cost depends on access, the parts or materials needed, how much has to be opened up or removed, and any permit or code requirement.
Our older house has a house trap, or running trap, in the basement. Why does it keep clogging?
Your basement drain backs up every so often, and each time someone points at the house trap and clears it again. In an older house that is a familiar story.
A house trap, also called a running trap, is a U-bend on the main drain near the foundation wall, with two cleanout plugs. It holds water to keep sewer air out. The trouble is that the dip slows the flow and gives solids a place to settle. Paper, grease, wipes and roots that pass through a straight pipe pile up in the bottom of the bend, so the trap becomes a frequent stoppage point.
Old lines make it worse. Scale in cast iron roughens the pipe and catches debris before it reaches the trap. Root intrusion at a clay joint outside sends fibres toward it. A bellied line downstream can hold water back so the trap never fully clears. Many traps were removed over the years, and local code on keeping or removing one varies.
One slow fixture is usually its own branch problem. If toilets, tubs, sinks and the washer all slow down together, or the floor drain bubbles, the trap or the main beyond it is the likely spot.
Safe homeowner check: Stop using water and look at the two trap plugs without opening them. Check whether the floor drain is holding water, and note which fixtures back up first.
Stop running water and call now if sewage is coming up from a floor drain or shower, if you smell sewage in the basement, or if a plug is weeping. Never loosen a trap plug under pressure, because sewage can surge out.
A cable machine is often enough to clear the trap itself when the stoppage is soft. Hydro jetting is the better choice when grease or scale lines the pipe on either side. A camera inspection is the right step when the trap keeps clogging, because it shows whether the real fault is a belly, a root-filled joint or a failing section further down.

Ask whether the trap can stay and be cleaned when needed, or be removed where code allows. The scope depends on basement access, the condition of the pipe on both sides, how much floor has to be opened up, and any permit or code requirement for changing the main.
We live in a manufactured home. Why do the drains under the floor keep clogging?
You live in a manufactured home, and the drains keep clogging. A sink runs slow, the tub gurgles, or the toilet backs up every few months. The cause is usually under the floor, where you cannot see it.
Drain lines in a manufactured home run through the belly wrap, between the floor framing and the ground. The runs are long and shallow, with very little fall, so water and solids move slowly and grease, soap and paper settle. Over time the hangers that hold the pipe can fail and the line sags. A sagging section becomes a bellied line that holds water and collects debris. Lightweight plastic pipe can also crack or pull apart at joints when the ground shifts.
Cold weather adds a problem. Pipes under the floor can freeze, and a frozen drain looks like a clog until it thaws. Roots can also reach the outside section where the home ties into the sewer.
One slow fixture is usually a branch or trap problem near that fixture. If sinks, tub, toilet and washer all slow down together, or water comes up in the lowest fixture, the main run under the home or the sewer connection is the likely spot.
Safe homeowner check: Run each fixture one at a time and note which are slow. Look for a cleanout outside near the home and see whether it holds water, without opening it under pressure. Do not crawl under the home if it is wet or smells of sewage.
Stop running water and call now if sewage is coming up inside, if water drips from the belly wrap, if the floor feels soft, or if the smell of sewage is strong under or around the home.
A cable machine is often enough for a soft clog in one branch. Hydro jetting is the better tool for build-up on the wall of a long, shallow run. A camera inspection is the right step when clogs keep returning, because it can show a sag, a cracked joint or a separated pipe.

Ask the plumber how they will reach the pipe and whether the belly wrap has to be opened and resealed. The scope depends on access under the home, how much belly board or insulation comes off, the pipe material, whether hangers need replacing to restore the slope, and any permit or code requirement.
