We just built or remodeled and the drains are already slow. Why?
The plumbing is new, and the tub drains like an old one. Or the sink gurgles whenever the washer runs. New work should not do this, and the cause is usually in how the pipe was set.
Four causes come up. First, not enough fall on a horizontal run. Water needs slope to carry solids, and a flat run leaves them behind. Second, a vent that was never tied in or was capped. The line cannot breathe, so you get gurgling and slow flow with no clog. Third, construction debris left in the line: grout, drywall mud, thinset, sand. It sets hard on the pipe wall. Fourth, a trap arm run too long.
One slow fixture points to its own trap arm, slope or vent. Several fixtures slow together, or the lowest drain backing up, points to the main run, a debris plug or a vent problem.
Safe homeowner check: note which fixtures are slow and listen for gurgling. Do not climb onto the roof. Stop running water and call now if water or sewage comes up in a tub or floor drain.
A camera inspection is the right first step on new work. It shows a flat section, a ridge of hardened material on the pipe wall, or a vent that never connected. Repeat cabling just pokes a hole through the problem, and it returns. A cable machine is enough for a soft, loose blockage. Hardened cementitious debris often needs hydro jetting. Slope and vent faults need the piping corrected, and what that involves follows access, materials, how much has to be opened up, and any permit or inspection.

Keep a record while the work is fresh. Photograph any open walls or trenches before they are closed, and write down the date the slow drains first showed up. If a builder or remodeling contractor did the work, the fault may be theirs to answer for. A written note from the plumber describing what the camera found, such as a flat section or hardened debris, helps far more than a general complaint.
Tell the plumber when the work finished, which fixtures were added and whether the main line was touched.
A common mistake is pouring strong drain chemicals into a new line. They rarely touch hardened grout or thinset, they can damage fittings, and they make later cabling or jetting unsafe for whoever handles it. Another is waiting for the problem to settle. Construction debris does not wash away. Ask whether any air admittance valves were used in place of a full vent, and whether local code allows them.
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.

My bathtub has a lever on the overflow plate and it drains slowly. Where is the clog?
Your tub has a lever on the overflow plate, the one you flip to close the drain, and now the water sits around your ankles. It drains slowly, and you want to know where the clog is. It is usually in one of two places.
Trip-lever drains have a plunger, or a stopper and linkage, that runs down inside the overflow tube behind that plate. A rod and spring connect the lever to the stopper at the bottom. Hair and soap scum wrap around that linkage and build into a mat that restricts the opening, even when the tub looks empty. If the linkage is out of adjustment, the stopper may also sit partly closed, so water slips through a narrower gap than it should.
The second place is the trap below the tub. Most tubs use a P-trap, and that bend collects hair, soap, and grease from bath oils. A clog there slows the whole tub even when the linkage is clean.
If only the tub is slow and the sink and toilet in the same bathroom work, the clog is almost certainly in the linkage or the trap. If the sink, shower and toilet also run slow, or the tub gurgles when another fixture drains, the problem is in the branch or main line.
Safe homeowner check: unscrew the overflow plate, pull out the linkage slowly, and clean off the hair and gunk. Check that the lever lifts the stopper fully. Run hot tap water, not boiling, to flush the drain. Avoid chemical openers.
Stop running water and call now if water backs up in the tub when the toilet or sink is used, if you see sewage, if there is water on the floor or ceiling below, or if a strong sewer smell shows up with the slow drain.
A cable machine is enough for a hair clog in the trap or a short branch. If the tub keeps slowing down, or several fixtures are involved, a camera inspection shows whether the cause is roots, a belly or grease coating the pipe. Hydro jetting is worth considering when the pipe wall is coated rather than plugged.

Ask the plumber whether the clog was in the linkage, the trap or further along, and whether the stopper needs replacing or adjusting. If the tub sits over a finished ceiling or is set in tile, ask how they plan to reach the trap. The scope depends on access, the parts or materials needed, how much has to be opened up, and any permit or code requirement.
The plumber wants to pull the toilet to reach the line. Why would they do that?
You called about a slow drain, and now the plumber says the toilet has to come off the floor. It is actually a common and sensible move, and it is often the cleanest way in.
A cable or jetting hose needs a way into the line. The best entry is a cleanout, a capped pipe fitting on the main drain. Many houses do not have one, or it is buried, painted over or blocked by a wall. Without a cleanout, the toilet is usually the best access point in the house. Pulling it exposes the closet flange and gives the plumber a short, straight shot into the closet bend and then into the main. Going in through a sink or tub means tight turns and a trap, and the tool may never reach the real problem.
It matters most when the blockage is past the branch lines. Roots at a clay joint, a belly holding water, or grease further down the main sit well beyond the bathroom. A straight path lets the cable or jet hose get there with enough control to clear it and, if a camera is used, to see what the pipe looks like.
Think about whether it is one fixture or the whole house. If only the bathroom sink is slow, the plumber should work at that sink. If the toilets gurgle, the tub backs up and a floor drain bubbles, the problem is in the main, and pulling the toilet is a reasonable way to reach it.
Safe homeowner check: look in the basement, crawl space or outside wall for a capped cleanout fitting on the main drain, and tell the plumber where it is. Do not pull the toilet yourself unless you are comfortable with it. The bolts can seize, and the bowl is heavy.
Stop running water and call now if sewage is coming up in a tub or floor drain, if the toilet is overflowing, or if you smell sewer gas.
A cable machine is enough for a simple clog near the closet bend. Roots, a belly or heavy build-up usually call for a camera inspection first, and hydro jetting to clean the pipe wall.

Ask the plumber if a cleanout will be added so the next visit does not need the toilet pulled. Also ask about the new wax ring and any damaged bolts or flange, since the toilet must be reset and sealed afterward. Scope depends on access, parts, the condition of the floor around the flange, and any code requirement for adding a cleanout.
The city is replacing the street main outside our house. Why are our drains acting up now?
The crew has been digging up the street for a week, and now your toilets gurgle, the tub drains slowly, or you saw muddy water in a floor drain. It is natural to suspect the work outside. There are a few real reasons why it can be connected.
Your house drain, called the lateral, runs from your foundation to a connection on the city main. When the main is dug up and replaced, that connection is cut and reattached. Vibration, trench work and heavy equipment can crack an older clay or cast iron lateral, push a joint out of line, or shift the pipe so water now pools in a low spot. Dirt, gravel and construction debris can also wash into the line while connections are open. The work can also cause temporary backups while flow is being rerouted or the new pipe is flushed.
The key question is whether it is one fixture or the whole house. A single slow sink is probably the fixture. If every drain is sluggish, gurgling or backing up at once, particularly the lowest ones, the trouble is in the lateral or the main, and the street work is a likely suspect.
Safe homeowner check: write down when the symptoms began and compare that to when work started near your address. Take photos of any muddy water, debris or wet floor. Check whether neighbors have the same trouble. Run one tap for a minute and see if the lowest drain in the house reacts.
Stop running water and call now if sewage is coming up in a tub or floor drain, if there is standing water in the basement, or if you smell sewage inside the house. Do not keep using the washer or dishwasher.
Tell the utility or the contractor promptly. They may have a claims process, and a delay can make it harder to show when the damage started. A cable machine may be enough if loose debris is the problem. If the lateral is cracked, offset or holding water, the plumber will need a camera inspection to see the damage, and hydro jetting can flush out silt and gravel.

Ask the plumber to record the camera inspection and write down the footage location of any damage, so you can give it to the city or contractor. Scope depends on how deep the pipe is, how much has to be dug up or opened, parts and materials, and any permit or code requirement. Responsibility for the repair varies by area, so confirm who owns which section of the line.
