What Clogs Corona Drains

Plumber in a safety vest feeding a drain cable into a sewer cleanout — Main line clogs are cleared through the cleanout, usually a capped pipe in the front yard near the house.

South Corona, Eagle Glen, Sierra Del Oro and Dos Lagos

These 1990s and 2000s tract homes drain through plastic pipe, which roots rarely get into. The clogs here come from use. Many are busy family households, and years of grease, food waste and soap build up inside kitchen lines until they narrow and catch everything. Corona's hard water adds mineral scale to the mix, which hardens that buildup and makes it cling. The result is a kitchen sink that backs up every few months and a main line that slows down over time.

Downtown and the older neighborhoods

Homes near downtown and along Sixth Street go back to the early and mid twentieth century, with clay sewer laterals and, often, cast iron drains inside. Roots get into clay joints and cast iron scales up and cracks, so main line backups there are more often structural than grease.

Coronita, Home Gardens and Temescal Valley mix both, depending on when each street was built.

Methods

How a Corona Drain Gets Cleared

Cable clearing

A motorized cable with a cutting head opens most sink, tub, toilet and main line clogs. It punches a hole through the blockage but does not clean the pipe walls, which is why a grease-coated line clogs again.

Hydro jetting

High-pressure water scours the full diameter of the pipe and flushes grease, scale and fine roots out to the main. For a Corona kitchen line that keeps clogging, jetting is usually what ends the cycle. See hydro jetting.

Camera inspection

A camera through the line shows whether the problem is buildup that jetting will clear, or a root intrusion, crack or sag that needs repair. In older downtown homes it is the step that decides the fix.

Main Line

Signs the Main Line Is Blocked

The kitchen sink and a bathroom both back up on the same day
Flushing an upstairs toilet sends water into the downstairs tub or shower
The washing machine drain makes the toilets bubble
Water seeps from the cleanout cap in the yard
A main line that was cleared last year is slowing again

Stop running water when you see these signs, since everything drained has nowhere to go but the lowest fixture. Inside city limits, the City of Corona maintains the sewer mains, and the lateral from the house to the main is the owner's to clear and repair. Unincorporated areas are served by other agencies. If sewage is already coming up, see emergency plumbing in Corona.

Prevention

Keeping Corona Drains Clear

Wipe greasy pans into the trash before washing, and let fats cool in a can.
Run the disposal with plenty of cold water, and keep fibrous scraps, rice and coffee grounds out of it.
Keep wipes, paper towels and hygiene products out of toilets, whatever the package says.
Put hair catchers in kids' showers and tubs, which see the heaviest use in most family homes.
Skip chemical drain openers. They rarely reach a main line clog and are hard on older pipe.
If a kitchen line clogs more than once a year, jetting it on a schedule costs less than repeated emergency visits.

FAQ

Drain Cleaning Questions in Corona

How much does drain cleaning cost in Corona?

A main sewer line typically runs $250 to $600 to clear, and hydro jetting a grease-heavy line $400 to $1,200 or more. Single fixtures cost less: about $125 to $300 for a sink or shower and $125 to $275 for a toilet. See drain cleaning prices.

Why does my kitchen sink keep clogging?

In most Corona homes, grease and scale have coated the inside of the kitchen line. Cable clearing opens a path through it, but the coating stays and catches the next clog. Hydro jetting cleans the full pipe wall, which is usually what stops it recurring.

Is hydro jetting worth it?

For a line that clogs repeatedly from grease or scale, usually yes. It costs more than cable clearing once, but it cleans the pipe rather than just opening it. On older clay or cast iron, a camera check first confirms the pipe is sound enough to jet.

Who is responsible for the sewer line in Corona?

Inside city limits, the City of Corona maintains the sewer mains. The lateral from the house to the main is the owner's responsibility to clear and repair.

Can a drain be cleared the same day in Corona?

Usually, yes. Most sink, toilet and main line clogs are cleared on the first visit. A line that needs a camera inspection or a repair may need a follow-up.
