Why does my basement floor drain back up when it rains?
A floor drain that backs up when it rains is usually not a clog in the drain itself. It means the sewer line outside the house is full, and the water has nowhere to go but up through the lowest opening, which is your basement floor.
Heavy rain can push extra water into the main line through cracked joints, root intrusion at a clay joint or a failed sewer lateral. The line fills, and the floor drain shows it first.
Safe homeowner check: on a dry day, pour a bucket of water into the floor drain and see if it runs away normally. Keep stored items off the floor, and do not run the washer, showers or dishwasher during the storm.
Stop running water and call now if sewage is rising, the smell is strong, or every drain in the house is gurgling or backing up. That points to the main line, not one fixture.
A cable machine can clear roots or grease when a blockage is the cause. If the line keeps filling in wet weather, a camera inspection is the next step, because it shows whether the pipe is cracked, bellied or breached. Hydro jetting washes the pipe wall once the cause is known. Cost depends on access, how much has to be opened up, the materials involved and any permit requirement.

Pay attention to how fast the drain responds, because it tells you how serious the cause is. If the water rises within minutes of a downpour starting and drops soon after it ends, the line is being overloaded by water entering through cracks or joints. If it stays up for hours after the rain stops, something is also holding water in the pipe, such as a belly or a root mass. Older homes often have clay or cast iron lines with many joints and sometimes a downspout or foundation drain connected to the sewer, which makes wet-weather backups more likely. Newer homes with plastic pipe usually have fewer joints, so a backup there points more strongly to a blockage or a municipal main running full. Tell the plumber when the backups began, how heavy the rain was, and whether any gutters or sump discharge are tied into the house drains. Once the cause is fixed, the floor drain should stay quiet through storms.
My shower drains slowly. What should I check before calling?
A shower that drains slowly is usually a single fixture problem, and that matters. Hair and soap scum catch in the strainer and the trap just below it. That is a different job from a main line problem, where every drain in the house runs slow.
Safe checks you can do yourself: lift the strainer or stopper and clear what is sitting on it. A plastic drain strip, the kind with small barbs, pulls hair out of the first few inches of pipe. Flush with hot tap water afterwards. Then test the others. Run the bathroom sink and flush the toilet while watching the tub. If water rises or bubbles in the tub, the problem is past this fixture.
Chemical drain openers are best avoided. They sit in a standing pipe, can damage fittings, and are a hazard to whoever opens the line next.
Stop running water and call if the toilet gurgles when the shower empties, if there is a sewage smell, or if water comes up in any drain. Gurgling can point to a blocked vent stack, and slow drains everywhere can point to the main line.
A cable machine is usually enough for hair and soap in a branch line. If it keeps coming back, a camera inspection shows why. Expert Plumbers Co is a referral service, not a plumbing company. We refer you to a local plumber for Drain Cleaning in Duncan, SC: (380) 262-9173.
One more thing to check is whether the problem is the shower drain itself or the pipe it sits in. If the strainer is clear and the water still pools, try removing the cover and looking at how the drain body is built. Some tubs have a pop-up stopper or a trip lever linked through the overflow, and a bent or hair-wrapped linkage can hold the plug partly shut. In older homes the tub may use a lead or cast iron trap further down that fills with soap and hair, while newer showers have a plastic P-trap that is easier to reach from below. A common mistake is pouring boiling water down the drain, which can soften plastic fittings and loosen joints. If the water level drops only after a long wait, even once the strainer is clean, the blockage is deeper in the branch and needs a plumber's tools.
Why did my drains stop working in freezing weather?
Every drain in the house is slow or dead, something is gurgling, and it started on a hard-frost morning. Where Duncan, SC gets a hard freeze, that usually points to ice in a pipe or ice at the top of the vent stack.
Frozen lines first. In colder states a sewer lateral can sit shallow enough for frost to reach it. Any sagging section holds a little water, and that water turns to ice. An un-insulated drain in a crawlspace or garage can freeze the same way.
Then the vent stack. Warm, damp air rises through the vent and meets freezing air at the roof opening. Frost builds ring by ring until the opening closes. With no air coming in, drains cannot flow. That is the gurgling you hear.
A frozen line and a root blockage look identical from inside the house. Both give slow drains and standing water. The weather, or a camera inspection, tells them apart.
Do not pour boiling water down a frozen line. Sudden heat can crack cast iron or split a trap, and then you have a leak too.
Safe homeowner check: see whether one fixture is slow or every drain is, look at the roof vent from the ground, and feel exposed pipe for a cold, stiff section.
Stop running water and call now if every drain is backing up, water is rising in a tub or floor drain, or you smell sewage. A single slow sink is usually a trap or branch job a cable machine can clear. A whole-house freeze-up or a suspect lateral may need a camera inspection, thawing equipment or hydro jetting, which is where emergency drain cleaning comes in.

Once the thaw is done, expect the problem to come back unless the cause is fixed. If a shallow section froze, ask the plumber to note its depth and whether the pipe has a belly that holds water, since that spot will freeze again. A cold crawlspace or garage drain can be wrapped with pipe insulation, and heat tape made for drain lines can help in short cold snaps, but it must be installed to the maker's instructions. For a frosted vent, keep snow clear around the roof opening, and tell the plumber if the vent is narrow, since a wider vent closes up less quickly. In older homes the vent opening is often smaller and the drains less well insulated, so the same cold snap hits harder. After a freeze, watch for leaks at joints and traps as the ice melts, because expanded pipe can split quietly and only show water once it warms. If you see damp spots later, tell the plumber what happened.
My house is old and the sewer might be Orangeburg pipe. What does that mean for cleaning?
Orangeburg is a pipe made from wood pulp fibers pressed together and sealed with pitch, also called bituminous fiber. It was used for house sewer lines in the middle of the last century, and some homes still have it between the building and the street. It was never as strong as clay, cast iron or modern plastic.
Over time the pipe softens and loses its shape. It can turn oval, sag, flake at the inside wall or collapse. Joints are easy targets for roots. So an old house with repeated backups and a history of roots or low spots may be sitting on this kind of line, though only a camera can confirm the pipe material.
That matters for cleaning, because the usual tools are rougher on Orangeburg than on other pipe. A heavy cutting head on a cable can tear at a soft wall. High pressure from a jetting nozzle can strip layers off or push through a weak spot. A plumber who knows or suspects the material will start with a camera inspection, use gentler tools, and avoid forcing a machine through a section that has already deformed.
Tell the plumber on the phone how old the house is, any earlier line repairs, and whether the line has been cleaned before. If you can, mention what you have seen: slow drains, a repeat clog, wet soil over the line.
Safe checks you can do:
Ask whether any earlier paperwork notes the pipe type. Limit water use if backups are frequent.
Stop running water and call now if sewage is coming into the house or the yard.
Cleaning may buy time on a line in fair shape, but it does not strengthen the pipe. If the camera shows a collapsed or badly ovaled section, the realistic options are lining where the shape allows it, or replacing the line. Cost depends on pipe length and depth, access, what has to be dug or removed, the repair method and permits under local code.

The furnace or air conditioner drains into my basement floor drain and now it overflows. Is that a drain cleaning job?
"The furnace drains into my basement floor drain and now it overflows." That is a common one, and it is a drain problem with two parts. The overflow can come from either end: the small condensate line, or the floor drain it empties into.
Condensate lines clog with algae and sludge. Once it blocks, water backs up at the unit or spills from the line onto the floor. Many systems also have a trap on that line, and the trap is the first place sludge collects.
The floor drain itself can be the problem. If it is slow or backs up when you run the washer or a tub upstairs, the cause is in the house drain: grease build-up, a bellied line holding water, or root intrusion at a clay joint further out.
One slow floor drain, with the rest of the house draining fine, usually means a local blockage in that branch. Every drain in the house backing up, or the lowest drain gurgling and rising while others run, points to the main line or a failed sewer lateral.
Safe homeowner check: Look at the pipe from the unit. Is water standing in the pan or trap? Pour a bucket of water into the floor drain and watch how fast it goes. Do not pour bleach or drain chemicals into the condensate line without knowing the unit's instructions.
Stop running water and call now if the floor drain is bringing up sewage or a sewer smell, other drains in the house are slow or gurgling, water is spreading toward electrical equipment or the furnace, or the overflow comes back soon after you clear it.
A cable machine is often enough for a plain clog in the floor drain branch. A condensate line is a different job: it needs flushing or clearing at the line and trap, and may need a cleanout fitting added. If the floor drain keeps backing up, a camera inspection shows whether the main line has roots or a belly. Hydro jetting is used when grease or scale coats the pipe wall.

Ask the plumber to check both the condensate line and the floor drain, and to explain which one failed. Ask whether the condensate should drain somewhere else, since rules vary by area on where it may discharge. Cost depends on access, the parts needed, how much has to be opened up or removed, and any permit or code requirement.
