Quick answer: A blocked drain that backs up, overflows or will not drain at all needs a plumber, not more drain cleaner. Stop using that fixture and call our 24/7 line to get a licensed plumber who clears the line with a drain machine or hydro jetting and checks whether the main sewer line is involved.
Do this right now
- Stop running water into the blocked sink, tub or floor drain.
- Check other drains: if several are slow or one drain backs up when another is used, treat it as a main line problem.
- Do not pour in more chemical drain cleaner, especially before a plumber works on the line.
If water or sewage is coming up from the lowest drain, see sewer backup repair.

Clogged drain: call now or can it wait?
A single slow drain can usually wait. Water coming back up, or several drains at once, cannot.
- Call now
Water backing up from a floor drain
Stop the washer and other water use, then call. - Call now
Several drains slow or backing up together
This points to the main line. Call before it overflows inside. - Same day
A kitchen sink that is full and will not drain
No flood risk if you stop using it, but book a same-day visit. - Can wait
One slow bathroom sink or tub
Often hair or soap near the drain. Try a plunger, then book a regular visit.
One slow drain or several?

| What you see | What it usually means |
|---|---|
| One sink or tub drains slowly | A local clog: hair, soap or food near that fixture |
| The kitchen sink backs up into the other side of the sink | A clog in the kitchen branch line, often grease |
| The washing machine makes a sink or floor drain overflow | A partly blocked branch or main line |
| Several drains are slow or gurgle together | The main sewer line: see sewer backup repair |
When is a clogged drain an emergency?
- Water is overflowing or about to overflow onto floors or cabinets
- A floor drain, tub or shower is filling with dirty water you did not run
- The only kitchen sink or only shower in the home is fully blocked
- Several drains are slow or gurgling at the same time
- You smell sewage near a drain
One slow bathroom sink that still drains can usually wait for a regular appointment.
Are chemical drain cleaners safe for my pipes?
They often fail on a full blockage and leave caustic water sitting in the pipe, which can harm older pipes and burn the person who opens the drain next. A plunger or a small hand auger is safer for a minor clog. If you already used a chemical cleaner, tell the plumber before work starts.
What the plumber does
- Asks which drains are affected to tell a local clog from a main line problem.
- Clears the drain through the fixture, the trap or a cleanout.
- Runs water to confirm the line drains at full speed.
- Uses a camera if the clog keeps coming back, to look for roots, a sag or a broken pipe.
- Explains the cause and the price before any extra work.

Snaking or hydro jetting?
| Method | When it is used | Limits |
|---|---|---|
| Hand or machine auger (snake) | Most single-fixture clogs: hair, soap, food, small objects | Punches a hole through buildup; grease can return |
| Hydro jetting | Grease, sludge and roots that keep coming back | Not for broken or very old fragile pipe; the plumber checks first |
| Camera inspection | Repeat clogs or a suspected broken pipe | Finds the cause; does not clear it |
A good plumber starts with the simplest method that will clear the line and only suggests jetting or a camera when the clog keeps returning.
How fast can a drain be cleared?
Most single-drain clogs are cleared in one visit once the plumber reaches the trap or a cleanout. Arrival time depends on your location and the time of day; ask for the expected arrival time when you call. Grease buildup and repeat clogs take longer, especially if jetting or a camera is needed.
What changes the cost of emergency drain cleaning?
- Which drain and how far down the clog is
- Access: a reachable trap or cleanout is faster than removing a fixture
- The method: auger, hydro jetting or both
- Whether a camera inspection is needed
- The time of the call (see how after-hours pricing works)
You get the price before work starts.
How to keep a cleared drain from clogging again
- Kitchen: wipe grease into the trash and use a sink strainer
- Bathroom: use hair catchers in tubs and showers
- Run hot water after using the garbage disposal
- If the same drain clogs every few months, have the line camera-inspected
What usually blocks each drain
| Drain | Common cause | Tip |
|---|---|---|
| Kitchen sink | Grease, food scraps, coffee grounds | Scrape plates into the trash; never pour grease down the sink |
| Bathroom sink | Hair, soap and toothpaste buildup | Clean the pop-up stopper every few months |
| Tub and shower | Hair and soap scum | Use a hair catcher |
| Laundry standpipe | Lint and fabric fibers | Use a lint trap on the washer hose |
| Floor drain | Dirt, debris or a main line problem | If it backs up, check the main line |
