When a clogged drain is an emergency
A slow bathroom sink can wait until morning. A toilet that bubbles when the washing machine drains, a tub that fills with gray water, or sewage rising in a floor drain cannot. Those signs point to a blockage in the shared line, and every flush or load of laundry sends more water into your house.
We treat that situation as an after-hours call at any hour, including weekends and holidays, and we book a same-day visit when a technician is free. The first step on arrival is to find which fixtures share the blocked section, because that tells us whether the clog is in a branch line or in the main line out to the street.
Stop adding water
Hold off on showers, laundry and dishwasher cycles. Every gallon you add has nowhere to go but the lowest opening in the house.
Do not mix chemicals
Skip the second bottle of drain cleaner. Caustic liquid sitting in a standing clog can splash on the technician and eats into old metal traps.
Find the cleanout
If you can locate the capped cleanout near the house or by the curb, tell us. It is usually the fastest place to start clearing the line.
Protect the floor
Move rugs and cardboard boxes away from low drains, and photograph any water for your insurance file before cleanup.
What your symptoms are telling us
One fixture drains slowly
Usually hair, soap film or grease in that fixture's own trap and branch. A cable or a small jet clears it without touching the rest of the system.
Two or more fixtures slow together
The blockage sits downstream where those lines meet. This is the pattern we see when a kitchen line and a bathroom line both back up in a ground-floor home.
Water rises in the lowest drain
A tub or floor drain that fills while a toilet flushes means the main line is restricted. Treat it as urgent and stop using water.
The clog returns every few weeks
Repeat clogs point at roots, a belly in the pipe or scale on old iron. That is the cue to run a camera instead of clearing the same blockage again.
How we clear it: cable, jet or camera
Most calls start with a cable machine, a motor-driven steel cable with a cutting head that bores through the clog. We choose the head size to match the pipe so the cable does not skip past the blockage or tear a hole through soft pipe.
If the cable keeps hitting resistance or comes back with roots, we step up to a hydro-jetting pass, which scours the pipe wall with high-pressure water. A short sewer camera inspection afterward shows whether the pipe is sound or needs sewer line repair.
| Method | Best for | Trade-off |
|---|---|---|
| Hand auger or small cable | A single sink, tub or shower branch | Cheaper and fast, but it only reaches a few dozen feet |
| Drum cable machine | Kitchen lines, laundry stacks and main line clogs | Cuts through roots, but leaves the pipe wall coated with residue |
| Hydro-jetter | Grease, scale and root regrowth | Cleans the whole pipe wall, but needs a sound pipe and a cleanout |
| Camera inspection | Clogs that return or sound pipes that still back up | Adds a short visit but shows the real cause |

Kitchen sink and dishwasher clogs
Kitchen lines clog because cooking fat cools inside the pipe and traps food particles. In many Pleasant Hill kitchens the sink, the dishwasher drain and the disposal all share one run, so a grease plug backs up all three at once.
We clear the line, then check the disposal outlet and the dishwasher's high loop, since a kinked hose can make a healthy line look blocked. If the disposal itself hums or leaks, our garbage disposal repair page covers that side of the job.
Why drains in older Pleasant Hill homes keep clogging
Pleasant Hill grew quickly after the war. The post office opened in 1948, and the Gregory Gardens subdivision was developed in 1950. In houses of that era, galvanized steel supply lines and cast iron or clay drain lines were common, and a plumber checks what is really in the wall instead of assuming.
Roots are the other big factor. Central San, the district that serves Pleasant Hill, calls root intrusion the leading cause of sewer backups and advises a professional inspection or cleaning at least every other year when trees stand near the lateral. That advice is worth following if your lot has mature trees along Contra Costa Boulevard or the Iron Horse Trail side streets.
Shower, tub and floor drains
Showers clog with hair and soap scum a few inches below the strainer, and a drain tool can usually pull it out in minutes. Tub drains that gurgle when a toilet flushes are the more serious case, because they tell us the shared line is partly blocked.
Floor drains in garages and laundry rooms are a quiet trouble spot. They often sit dry for months, then fail when the washer discharges, so we test them with a bucket of water before we leave.
What affects the price of a drain cleaning
Every drain job is different, and we give a clear price before work starts. These are the factors that move it:
Homeowners policies often cover sudden water damage from a backup only with a sewer or drain backup endorsement, so read your policy before you call the insurer.

Where we clear drains
We work every ZIP in the city, including 94523 on Contra Costa Boulevard, and we cover nearby streets in 94518 and 94520 on the Concord side. Our Concord plumber page lists the neighborhoods on that side, and we also take calls in Walnut Creek when a line backs up south of the BART station.
Drain and vent layout in California homes follows the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). That is why a new fixture needs its own trap and vent, and why we check venting when a drain gurgles.
Common questions
Yes. The line is answered 24/7, and a plumber is booked the same day when one is available. Call, describe which drains are backing up, and we will tell you what to shut off while you wait.
Run the tub and toilet separately. If only one drains slowly, the blockage is in that branch. If several fixtures back up together or the lowest drain fills, the main line is restricted.
We advise against it for a standing clog. The liquid sits in the pipe, can burn skin during the repair, and does little against grease or roots.
A correctly sized head will not harm sound pipe. If the pipe is cracked or crushed, the camera shows it, and we explain repair options before doing more work.
Repeat kitchen clogs usually mean grease has built up deeper in the line than a cable reaches. A jetting pass removes it, and a camera shows whether the pipe has a low spot holding water.
Central San says the owner is responsible for the entire lateral from the house to the public sewer connection, including the part under the sidewalk and street. We can inspect it with a camera.
