Main Line Clogs
The main drain carries everything out to the street. Roots, grease and old pipe joints can choke it. We open it from the cleanout with a heavy cable or water jet, then run a camera if the clog keeps returning.
Sink full of standing water? Shower draining slower every week? Laundry water spilling across the floor? Our drain cleaning crew in Yorba Linda clears the clog, finds out why it formed, and gives you a straight answer on how to keep it from coming back. Same day service in most cases.

When two or more fixtures act up at the same time, the clog is usually in the main drain, not a single sink. A blockage in one fixture stays in that room. A main line clog shows up in several places, often at the lowest drain in the house first.
Several drains backing up? Call before it overflows
Every drain clogs for its own reasons. Here is what we clear most often and how we handle each one.
The main drain carries everything out to the street. Roots, grease and old pipe joints can choke it. We open it from the cleanout with a heavy cable or water jet, then run a camera if the clog keeps returning.
Cooking grease cools inside the pipe and traps food scraps. Over time the opening shrinks until the sink holds water. We cut through the buildup and flush the line clean.
Hair and soap form a tight mat a few inches below the drain. We pull it out and clear the trap without damaging the finish.
Toothpaste, hair and soap scum slowly close the line. We clear the trap and the pipe behind the wall.
Lint from the washer builds inside the standpipe and the line behind it. We clear it so a full load drains without spilling.
Garage, patio and yard drains fill with leaves and dirt. We clear them so rain and wash water drain away from the house.
If a clog points to a broken or root filled pipe, our sewer line repair team takes it from there. For a toilet that keeps clogging, see toilet repair.

Small daily habits keep most household drains clear for a long time. Keep grease out of the kitchen sink, catch hair at the shower drain, and run hot water after heavy use.
Hard water, older drain lines and mature trees make clogs more common across Yorba Linda, from the tracts off Yorba Linda Boulevard to the hillside streets near Chino Hills State Park.
Mineral scale
Local well water averages about 20 grains of hardness, and scale slowly narrows the inside of older pipes so debris catches faster.
Decades old drain lines
Many homes built in the 1970s and 1980s still have their original drain and sewer pipes, and older joints give roots and debris a place to grip.
Mature landscaping
Big trees planted when neighborhoods were new now send roots toward the moisture in sewer lines.
Kitchen grease
Grease is the top cause of kitchen clogs in any home, and it builds faster in pipes already rough with scale.

Each room clogs for its own reasons, so the fix and the way to prevent it change from room to room. Here is what usually builds up in each drain.
| Room | What usually causes the clog | How to prevent it |
|---|---|---|
| Kitchen | Cooking grease, food scraps, coffee grounds | Keep grease out, use a strainer, run cold water with the disposal |
| Bathroom sink | Hair, toothpaste, soap scum | Clean the stopper monthly |
| Shower and tub | Hair mixed with soap | Use a hair catcher |
| Toilet | Wipes, paper towels, too much paper | Flush only toilet paper |
| Laundry | Lint and fabric fibers | Use a lint trap on the washer hose |
| Garage and patio | Leaves, dirt, debris | Keep grates clear before rain |
| Main line | Roots, grease, broken pipe joints | Camera check when clogs repeat |
A cleanout is a capped pipe that gives a plumber direct access to your main drain line. It is usually outside near the front or side of the house, close to where the sewer line leaves the home, and it often has a round plastic or metal cap a few inches above the ground.
Knowing where it is helps in two ways. First, the plumber can clear a main line clog through the cleanout instead of pulling a toilet. Second, during a backup, a cleanout that is full of water tells you the blockage is past the house. If your home does not have an outdoor cleanout, or it is buried under landscaping, adding or uncovering one can make future drain work faster and cleaner.
Store bought chemical drain cleaners promise a quick fix, but they often leave a bigger problem behind.
A plunger, a hair tool or a call to a plumber is the safer path. If you have already poured a cleaner in, tell the plumber before they start.
Most household drains only need professional cleaning when they slow down or clog. A drain that clogs more than twice a year usually has buildup deep in the pipe and benefits from a jetting visit.

Repeat kitchen clogs usually come from grease that coats the inside of the pipe. A cable punches a hole through it, but the coating stays and catches food again. Hydro jetting scours the pipe walls clean, which keeps the line open much longer. Keeping grease out of the sink also helps a lot.
In most cases, yes. We check the line with a camera first when the pipe is old or damaged. If the pipe is cracked or weak, we adjust the pressure or recommend a repair instead. Jetting is often the best way to clean a healthy older line that keeps clogging with grease or scale.
If only one sink or tub is slow, the clog is usually in that drain. If flushing the toilet makes water rise in the tub, or several drains back up together, the main line is likely blocked. In that case, stop running water and call so the backup does not spill into the house.
In most cases, yes. We offer same day drain cleaning across Yorba Linda, so a call in the morning or early afternoon usually gets a plumber to your home that day. If sewage is backing up into the house, tell us right away so we can treat it as an urgent call.
Most household drains only need attention when they slow down. If one line clogs more than twice a year, a professional cleaning or jetting visit makes sense. Restaurants and homes with heavy kitchen use often benefit from a yearly jetting to keep grease from building up.
Yes, a root cutting head on a drain cable or a hydro jet can cut roots out of a sewer line and reopen it. The catch is that roots grow back through the same crack or loose joint. If roots keep returning, a camera inspection shows whether the pipe needs a repair so the roots cannot get back in.
A slow drain only gets worse with time. Call now, tell us which drains are acting up, and we will get a plumber out to clear it and show you the cause.
