What does grease actually do to a drain pipe?
Grease leaves the sink as a liquid, and the pipe is where it stops being one. Warm fat cools on contact with the cold pipe wall and hardens into a waxy layer. That layer is slightly sticky, so it grabs coffee grounds, food scraps, and lint, and each meal adds another coat. Over weeks the opening shrinks like an artery, and water that used to flow freely starts to drain slowly and gurgle. Hot water does not fix this; it only carries the grease farther down the line, where it cools and sets again, sometimes in the main. That is why a kitchen sink that slows while every other fixture drains normally is nearly always grease in the branch line close to the trap. A cable machine cuts a channel through the buildup and often restores flow, but the coating stays on the pipe wall and narrows again within weeks. Hydro jetting sends high-pressure water around the whole interior and strips the grease off the pipe wall, which is why it is the usual answer for repeat kitchen clogs. Wiping pans with a paper towel and putting fat in the trash prevents most of it. Expert Plumbers Co connects homeowners with an independent local plumber who can tell whether a cable or a jetter fits the line. Access and the amount of buildup affect the job.
The place where most people go wrong is the hot water habit. Running hot water for a few seconds after washing dishes does not carry grease to the sewer, it only moves it down the line a few feet, where it cools and sets. A much better routine is to scrape plates into the trash, wipe greasy pans with a paper towel, and keep a jar for cooking oil that can go in the garbage once it is full. Dish soap makes grease look like it has dissolved, but it only breaks it into smaller droplets that still stick further along. Garbage disposals do not solve this either, since they chop food without removing the fat. In restaurants and busy households, a grease trap or interceptor may be present, and it needs regular emptying. If the sink has slowed repeatedly, mention that to the plumber, since a pattern points to a coating that needs scouring rather than another quick clear.
Can my downspouts or sump pump cause a sewage backup?
Every drain is gurgling and dirty water comes up the basement floor drain, but only when it rains. That is not one slow sink. Storm water is a prime suspect.
In older housing stock, gutters, a yard drain or a sump pump discharge were sometimes plumbed straight into the sanitary sewer. In a storm, all that extra water floods the house lateral and the municipal main. The pipe runs full, so sewage is pushed back up the lowest opening: a floor drain, a basement shower, a laundry standpipe.
Many jurisdictions now prohibit this. Disconnecting it is often a permit or code matter.
Safe homeowner check: walk the outside of the house. See where each downspout ends. Does it spill onto the ground, or vanish into a pipe in the soil? Does the sump pump discharge run out to daylight, away from the foundation, or into a pipe tied to the house drain? Look only. Do not dig.
Stop running water and call now if more than one fixture is backing up, if sewage is rising, or if it is reaching the floor. A single slow sink is a different job, and a cable machine usually handles it. A storm-driven backup is not a clog, so cabling will not cure it.
A plumber finds the connection with a camera inspection, which shows a tie-in on the pipe, or a dye test, where colored water poured into a downspout or sump shows up in the sewer. What the work involves depends on access, the materials, how much has to be opened up, and any permit requirement.

Once the connection is found, the usual fix redirects the storm water instead of changing the sewer. Downspouts can be extended to discharge onto the ground well away from the foundation, with the soil graded to carry water off. A sump discharge should run outdoors to daylight or to a drainage point that local code accepts.
A common mistake is capping the old pipe at the wall and leaving the buried tie-in open to the sewer. An open stub can still admit soil, roots and water. Ask the plumber to confirm the old connection is sealed at the sewer end, not just hidden from view.
Sump pumps run hardest during the very storms that load the sewer, so a pump that cycles constantly is worth mentioning on the call. After the change, watch the next heavy rain. The floor drain should stay quiet. If it still gurgles, the cause may be the street main or a damaged lateral, not the tie-in.
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.
We are buying a house. Is a sewer camera inspection before closing worth it, and what does it find in older homes?
A standard home inspection covers what can be seen and reached. It does not follow the main drain out under the yard, and that buried pipe is where the expensive surprises sit. On an older house, a camera inspection of the sewer line before closing is usually worth doing.
A plumber feeds a small waterproof camera down the line, normally through a cleanout, and watches the pipe on a screen. The run goes from the house toward the street connection, and the plumber notes how far along each problem sits.
Here is what tends to turn up in older homes:
Tree roots in clay or concrete pipe, entering at joints. They look like fine hair or a thick mat.
Cast iron that has scaled up inside, narrowing the bore, or has cracked along the bottom.
Fiber pipe made of tar and wood pulp, which can go oval and collapse over time.
A bellied section, where the pipe has sagged and holds a pool of water.
Offset or separated joints where the soil has moved, and old broken sections from past digging.
Ask for the video or screenshots, and for the distance of each defect from the cleanout. That gives you something concrete to show your agent and the seller. A root problem that a cable machine or hydro jetting can clear is a very different matter from a collapsed section that needs digging or a trenchless liner. What a repair costs depends on depth, access, how much yard, driveway or slab has to be opened, the materials, and local permit rules. Those are the things to ask a plumber about once the footage is in hand.
Two practical points. First, find out whether the cleanout is reachable, and tell the seller you need access during your inspection window. Second, a camera cannot see through a line that is full of water or packed solid, so the plumber may need to clear it first. If the seller says the line has never given trouble, that is useful, but it does not show the condition of the pipe.
Ask also whether the lateral is shared with a neighbor, since that changes who deals with a defect.

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.
