Drain & Sewer Repairs in Corona

Water backing up into a shower or floor drain when the washing machine runs? That’s not a clogged trap, it’s usually a downstream blockage in the main line, and it calls for a different tool than a store-bought snake. Recurring clogs, gurgling toilets, slow drains across multiple fixtures at once, or sewage odor in the yard all point to the drain or sewer line itself rather than a single fixture. That’s the problem this service solves.

What Drain & Sewer Repairs actually involves

Drain and sewer work covers everything from a single stubborn kitchen line to a full sewer lateral replacement under the front yard. The line between “drain cleaning” and “sewer repair” is usually the camera: once we can see root intrusion, a bellied pipe, or a cracked clay joint, the job shifts from clearing a blockage to repairing or replacing the section that’s actually failing. Equipment ranges from cable augers for routine clogs to hydro jetting for grease and scale buildup, to trenchless pipe lining or pipe bursting when a section needs to be replaced without tearing up a driveway or mature landscaping. Most diagnostic visits take under an hour; repairs range from a same-day cable clearing to a multi-day trenchless or excavation job depending on what the camera finds.

Our process

1. Camera inspection. A sewer camera goes down the line first, before any cutting or digging, to find out exactly where the problem is and what’s causing it: roots, a belly, a collapsed section, or buildup.
2. Locate and mark. If a dig or trenchless repair is needed, we locate the exact position and depth of the problem using the camera’s sonde and surface locator so we’re not guessing where to open the yard.
3. Clear or repair. Routine blockages get cleared with cabling or hydro jetting. Structural problems (cracks, breaks, offset joints, root-damaged clay or cast iron) get repaired with trenchless lining, pipe bursting, or traditional excavation, whichever fits the depth, access, and condition of the existing line.
4. Flow verification. After the repair, we run water and re-camera the line to confirm flow is restored and the repair holds under normal use, not just a quick test.
5. Cleanup and documentation. Any excavation gets backfilled and the site restored; photos and camera footage are kept on file in case you need them for a permit sign-off or insurance claim.

What separates a good drain and sewer response from a bad one

The most common mistake is skipping the camera and jumping straight to cabling. Cabling can clear a blockage temporarily while leaving the actual cause, a root mass, a bellied section, a separated joint, untouched, which means the same clog comes back in a few months. A thorough diagnosis means running the camera the full length of the line, not just to the first obstruction, so a secondary problem further down doesn’t get missed.

On older clay and cast iron lines, another mistake is treating every blockage as a cleaning job when the pipe itself is failing. Hairline cracks in clay let roots in repeatedly; cast iron scales down from the inside until the effective diameter is a fraction of what it was installed at. Insurance adjusters and plumbing inspectors both look for camera footage that shows pipe material and condition, not just “cleared successfully,” because that’s what distinguishes a maintenance clean from a line that needs to be replaced.

What does Drain & Sewer Repairs cost?

Costs vary widely depending on whether the job is a routine cable clearing, a hydro jetting, or a trenchless or excavation repair, and depth, pipe material, and yard access all factor in. These are typical industry ranges, not a quote: every property is different, and RT Olson Plumbing, Heating and Air Conditioning provides a written scope of work with pricing before any repair begins. Homeowners insurance typically covers sudden pipe failures and the resulting water damage, but it generally does not cover line replacement due to age, root intrusion, or wear, which is treated as a maintenance item.

Seasonal & regional considerations

Corona’s older neighborhoods, particularly homes built from the 1950s through the 1970s, often still run on the original clay or cast iron sewer laterals, materials that are especially prone to root intrusion and joint separation after decades in the ground. Mature trees common throughout these older lots send roots toward any available moisture, and a hairline crack in an aging clay line is often all it takes. Heavy winter rain can also saturate soil enough to shift a pipe that was already marginal, which is why a line that’s been “fine for years” can suddenly start backing up after a wet season.
