drain cleaning using a snake down a sink drain

Snaking the drain

When a drain clog has built up over time, is firmly rooted, and only snaking or rooting the drain will remove the obstruction and allow proper flow.

This is a job best left to the professionals. Let us take care of the mess for you and call RT Olson Plumbing at (951) 344-5596.

Camera Inspections

If there are slow drains or drain stoppages in your home or business that aren’t easily fixed with a plunger, it may be time for a video drain line inspection.

We’ll send a skilled technician with specialized equipment to find the reason your drain keeps slowing. A video drain line inspection can look deep into pipes and see exactly what is the problem is, eliminating guesswork and hit-or-miss repairs.

Hydro-jetting clogged drain by RT Olson Plumbing - Corona CA


For stubborn clogs deep in the sewer line or in outdoor landscaping drains, hydro-jetting is often the best cure.

This special equipment uses powerful water jets to cut through roots and other clogs in your drain line.

Hydro-jetting is also used to clean the scummy film that builds up on the inside walls of your drain pipe and creates unpleasant odors in the kitchen and baths.

Sewer Line Jetting, Repair, or Replacement

If camera inspection shows deep clogs or tree root invasions then our hydro-jetting sewer line service should get the job done for you.

Note: if the sewer pipe is cracked, crushed, or broken then it will need either section repairs or complete line replacement.

We provide sewer line jetting, repairs, replacement, as well as trenchless sewer repair using pipe liners.

See our sewer line repair service for more information.

Trenchless Sewer Repair

Trenchless sewer repair is an alternative sewer repair or pipe replacement service we provide that prevents the damage of digging an open trench along the entire pipe route and instead digs a hole at only one end of the pipe, cleans the pipe, and then inserts a pipe liner that expands and hardens inside the old pipe. All usually done in one day.

See our Corona CA trenchless sewer pipe repair service page for more information.

Clogged Drains – surface & subsurface

There are two basic categories of clogs:

1) clogs or blocks close to the surface (fixture drains)

2) clogs or blocks deeper in the main sewer lines.

 Pipes clogged close to the surface are usually blocked by:

  • grease or oil (in kitchen sink drains)
  • hair, soap scum, and dirt (in bathroom sinks, tub and shower drains)
  • feminine hygiene products, baby wipes, and dental floss (in toilets)

These are often fixable by the home-owner with some simple tools and know-how. Sometimes the clog is deep into the pipe and a professional is needed.

Deeper sewer-line clogs or blockages are commonly due to:

  • tree roots infiltrating the pipe
  • sludge buildup closing the diameter of pipes
  • corroding or collapsing pipes

These are fixable by a professional plumbing or drain-cleaning company using power rodding or hydro-jetting services.Damaged pipes may also require pipe-re-lining.

RT Olson Plumbing is a professional and experienced drain-cleaning company with over 18 years experience and over 5,000 jobs to our credit. We can help you with surface-level fixture clogs like sink drains, all the way to deeper sewer system clogs and obstructions.

Surface-Level Drain Clogs

Sink Drains, Garbage Disposals, Shower or Tub Drains, and Toilets

sink clog

Sink Clogs:

Kitchen sink clogs and bathroom sink clogs may just need the clog dislodged with an inexpensive sink plunger to get the obstruction moving freely down the line to larger pipes. Alternately, a clog in the P-trap or S-trap underneath the sink can be taken apart with simple tools, and the traps cleared my hand.

garbage disposal

Garbage Disposal Clogs:

The blades inside the device can get stuck from food accumulation.

To move stuck blades, you need the hex wrench that came with the unit ot one of your own.

Unplug the unit. Insert the hex key so you can manually rotate the blades of the disposal. Usually this frees the blades and gets any backed-up water draining. Reconnect the power, push the little red reset butotn in and you should be good to go.

Bathtub and shower drain clogs

may be fixed by vigorous pumping with a plunger. Also, the drain cover should be removed so that any hair and soap-scum clog may be removed within inches of the drain cover.

Toilet drain clogs

are also often fixed by using a plunger. If that is unsuccessful the next step is to use a drain auger (snake). If it’s still clogged then there are one or more clogs deeper into the sewer pipe. Video inspection would be next to find where the clog is and how many there are.

Deeper-level clogged sewer line

If you’re experiencing slow or gurgling toilet flushes, or slow drainage in multiple plumbing fixtures at the same time, it’s likely an issue is deeper down into your sewer line.

These deeper sewer-line clogs usually can’t be solved with plungers, chemicals, or 6-foot snaking tools. They require professional servicing.

Defective or damaged sewer lines can have potential health risks as they can allow sewage, mold, and bacteria into your home. Back-flow of raw sewage up your drains or over your toilet bowl is very nasty! It can cause extensive water damage. It can let mold and sewage bacteria flood into your home, lead to costly cleaning and repairs and health hazards.

A clogged or blocked sewer line should be diagnosed accurately and repaired quickly to save you thousands of dollars in potential repairs and cleaning and disinfecting services.

If you suspect a problem in your sewer line, it should be inspected for clogging, breakage, and penetration by roots.

See our main sewer line inspection & repair service for more information.

How can I tell if the clog is in the sewer line?

There are ways to tell the difference between a regular clog and a clogged sewer line. You may need emergency plumbing service if:

  • Multiple drains are slowing or backing up. If sinks, bathtub, shower are all draining slowly or failing to drain, there is a blockage deeper down in the sewer line they all share. Sometimes toilets, bathtub drains, and shower drains will make a gurgling noise when the main sewer line has a clog.
  • There is a smell of backed up sewage or mold coming from drains.
  • There is standing water in the sewer clean out. For homes built after 1978, there should be a wide (typically 4-inch diameter) white or black pipe with a threaded plug at or near the foundation. It’s an access to the sewer line. The plug has a raised square for the wrench. Unscrew this plug. If water flows out or is standing in the pipe, your sewer line is clogged.

We also provide main sewer line repair service for clogs, cracks, or broken pipes deep in the sewer line.
