Why do my drains back up only when I run the washing machine?
When the washing machine drains and water comes up in the shower or a floor drain, the machine is rarely the problem. It dumps a lot of water in a short burst, and the line behind it cannot carry that volume away. Something is narrowing the pipe: grease and lint built up on the pipe wall, roots pushing in at a clay joint, or a bellied section that holds water and slows the flow.
Where it shows up tells you a lot. If only the laundry standpipe overflows, the blockage is probably in the branch line serving the machine, and a cable machine often clears that. If the lowest drains in the house gurgle or back up too, the blockage is further down, in the main line or a failed sewer lateral. That is a different job. It usually calls for hydro jetting or a camera inspection to see what is actually in there.
Safe homeowner checks: make sure the drain hose is not jammed tight into the standpipe, and try a smaller load. Do not keep running loads to see if it clears. Every cycle pushes more water toward the lowest opening in the house.
If water is coming up inside the house, stop using the washer, sinks and toilets and call. Expert Plumbers Co is a referral service, not a plumbing company. We refer you to a local plumber for Drain Cleaning in Lexington, KY: (380) 262-9173.
Watch for a pattern in when it happens, because that helps separate a drain problem from a venting or plumbing layout issue. If the backup always appears on the second or third load, the line is partly blocked and fills as the volume builds. If the washer is on a long run that ties into the main near a bathroom, the surge can push air and water into the nearest fixtures. Older homes often have laundry drains that were added later with a smaller pipe or an awkward connection, which cannot keep pace with a modern machine. A common mistake is placing a lint trap on the end of the drain hose and assuming it solves everything. It catches fibers, but it does not clear buildup already in the pipe. Tell the plumber the machine type and how many loads you run in a day.
Small flies keep coming out of the drain. Is that a clog?
Possibly, but not always. Small flies rising out of a drain are drain flies. They breed in the organic film that coats the inside of the trap and the first few inches of pipe, not in clean standing water. The film is the nursery.
A slow or partly blocked drain gives that film somewhere to sit, which is why flies and a slow drain often show up together. A drain nobody uses is a different case. When its trap dries out, flies and sewer odor both come straight up the pipe.
Safe homeowner check. Tape a card or a clear bag over each suspect drain overnight. Flies on the underside show which one they come from. Clean the strainer and the visible part of the drain. On a rarely used drain, pour in a bucket of water to refill the trap.
A cable machine is enough when one fixture is slow and no flies are involved. A cable only cuts a channel through the blockage and leaves the film on the pipe wall. A line that keeps producing flies after cleaning usually needs hydro jetting, which strips the wall back to bare pipe.
One fixture is a local job. Flies plus several slow drains point further down the line: grease build-up on the pipe wall, a bellied section holding water, or root intrusion at a joint. That calls for a camera inspection before anyone picks equipment.
Stop running water and call if drains gurgle, sewage odor fills the room, or water rises in the lowest fixture.

The choice of cleaner matters. Bleach poured down the drain kills flies on contact but leaves the film they feed on, so they return within days. Boiling water helps on metal pipe but can soften or loosen joints on some plastic, so use hot tap water. A stiff brush on the strainer area and the first few inches of pipe does more than any liquid. An enzyme cleaner left overnight can digest the film, but treat it as upkeep, not a cure for a blocked line.
Check the overflow opening on sinks and tubs too. That channel is rarely cleaned and can breed flies.
Adult drain flies are weak fliers and rest on walls near the source, so counting them each evening shows whether cleaning is working. If the numbers do not fall within a week of thorough cleaning, the source is deeper in the line, or in a seldom-used floor drain in a basement or utility room that nobody thinks about.
When I run one side of my double kitchen sink, water comes up in the other side. Why?
When water from one basin rises in the other, both bowls are sharing a drain that is partly blocked downstream of where they join. The two basins feed a single tailpiece and trap, and the water has nowhere to go but back up the second bowl. The clog is almost never in the basin you are looking at.
The usual cause is grease and food residue that has built up on the pipe wall past the trap, narrowing the pipe until it can pass only a trickle. Sometimes the blockage sits in the horizontal pipe inside the wall, or further along where the kitchen line meets the main drain.
Safe checks you can do: run only the cold tap for a minute and see whether the water in the second bowl rises slowly or fast. Look under the sink for a leak at the trap and the connection between the two bowls. Remove the trap if you are comfortable doing so, with a bucket under it, and clear out what is inside. Skip chemical drain cleaner, since it sits in a standing pipe and can damage fittings and hurt whoever opens the trap next.
If the trap is clear and the water still climbs into the other bowl, the blockage is deeper. A cable machine is often enough for a soft grease and food plug. If the line clogs again within weeks, grease has likely coated the pipe wall, and hydro jetting scours it clean in a way a cable cannot. A camera inspection is worth asking about when the same line keeps returning, because it can show a bellied section holding water or a damaged joint that cleaning alone will not fix.
Stop running water and call promptly if the backup is also showing in other drains, if you smell sewage, or if water is coming up from a floor drain or toilet. That points to the main line rather than the kitchen branch, and every extra gallon you send down ends up on your floor.
Cost depends on access to the pipe, whether a cleanout is available, how far the blockage sits from the opening, and whether any section has to be opened up or replaced.

Will baking soda and vinegar, or a kettle of boiling water, clear a slow drain?
You have a slow drain, so you tried baking soda and vinegar, or a kettle of boiling water. It still crawls, or the clog is back by morning. That is the usual result.
The fizz is mild. It can freshen a drain, but it does nothing to a solid clog of hair, soap scum, grease or paper. Boiling water melts grease for a moment, then the grease cools and sets again further down the pipe, where it is harder to reach. Boiling water can also soften PVC joints and crack porcelain. Hot tap water is safer than a kettle.
The real causes sit deeper: grease build-up on the pipe wall, scale in old cast iron, roots entering a clay joint on the main, or a bellied line that holds water and solids at its low point. A blocked vent stack can also make a drain sluggish and gurgling, which looks like a clog but is an air problem.
Count the affected drains. One slow fixture usually means a hair, soap or grease clog in that fixture or its branch. If the tub, sinks and toilets all run slow together, or you hear gurgling after a flush, the trouble is in the main line or vent, and no kitchen remedy will reach it.
Safe homeowner check: Remove the stopper or strainer and clear hair and residue by hand. Try a plunger with a good seal. Run hot tap water, not boiling. Check whether other fixtures are slow. Avoid stacking store-bought chemical cleaners, which can sit in a standing pipe.
Stop running water and call now if more than one fixture is backing up, if dark water is rising in a tub or floor drain, if you smell sewage, or if water comes up when you flush or drain the washer.
A cable machine is usually enough for a clog in a single branch. Hydro jetting is the better tool when grease or scale coats the pipe wall. A camera inspection is the right step when the drain clears and slows again within days, since that pattern points to a belly, roots or a damaged section.

Tell the plumber what you already tried. Ask what they found in the line, not only that it was cleared. The scope depends on access to the pipe, whether a fixture has to be removed, the pipe material, and whether the cause is a simple clog or damage that needs repair.
Does drain cleaning or sewer line repair need a permit?
You need a drain cleared or a sewer line fixed, and you want to know whether the work needs a permit before anyone starts. The answer depends on what is being done.
Drain cleaning usually needs no permit. Clearing a blockage with a cable machine, running a hydro jet, or putting a camera in the line does not change the plumbing system, so most areas treat it as maintenance.
Repair or replacement of a building sewer usually does need one. The building sewer is the pipe from the house to the main in the street. Fixing a collapsed section, replacing a root-damaged clay line, or digging out a bellied run changes the system, so it is normally permitted and inspected. If the dig reaches the street, curb or public right of way, a separate permit may be needed. Rules vary by area, so check with your local building or public works office, or ask the plumber what applies in Lexington, KY.
The cause points the way. Root intrusion at a clay joint, grease build-up on the pipe wall, scale in cast iron or a blocked vent stack are usually cleaning jobs. A failed sewer lateral, a bellied line that holds water, or a broken pipe is a repair, and that is where permits come in.
One slow fixture rarely leads to a permit question. If every drain in the house is backing up, the main line is involved, and a camera inspection will show whether cleaning will do or a repair is needed.
Safe homeowner check: Find your cleanout and note where it is. Find out where your property line sits, since that affects who is responsible for which part of the line. Call your local building department and ask what work needs a permit.
Stop running water and call now if sewage is coming up inside, if the yard is wet or sunken over the line, or if you smell sewage. Safety comes before paperwork.
A cable machine is enough for a soft clog. Hydro jetting is the next step for grease or scale. A camera inspection shows whether a repair is needed, and that finding is usually what leads to a permit.

Ask the plumber who handles the permit, whether an inspection is required, and how that affects the schedule. The scope depends on how much of the line has to be opened up, access, parts and materials, any right-of-way work, and the code requirements in your area.
