What Riverside Drain Lines Are Made Of

Hand holding a cut section of drain pipe packed with buildup — Grease, scale and debris narrow a drain line over years, which is why the same clog keeps coming back.

Riverside is one of the oldest cities in the Inland Empire, and its drains show it. The Wood Streets, the area around Victoria Avenue and parts of downtown include homes built before World War II, and much of the rest of the city went up between the 1950s and the 1970s. Those homes typically drain through cast iron inside the house and a clay sewer lateral out to the street.

Both materials have known weak points. Cast iron scales up inside and eventually cracks, so the line narrows and catches everything. Clay laterals are laid in short sections, and the joints between them are where roots get in, especially in neighborhoods with mature street trees. Riverside's hard water adds mineral scale on top of grease in kitchen lines.

The east side is different. Orangecrest, Mission Grove and other newer tracts are mostly slab-on-grade with plastic drain lines, where clogs are usually grease, wipes and food waste rather than roots.

Methods

Cable Clearing, Hydro Jetting and the Camera

Cable clearing

A motorized cable with a cutting head opens a clog and is the right first tool for most sink, tub and toilet lines. It punches through the blockage but does not clean the pipe walls, so a line coated with grease or scale clogs again.

Hydro jetting

High-pressure water scours the full diameter of the pipe, washing out grease, scale and fine roots. It is the better choice for a kitchen line that keeps clogging or a main line with heavy buildup. On old cast iron and clay, a camera look first confirms the pipe is sound enough to jet. See hydro jetting.

Camera inspection

A camera run through the line shows roots, cracks, offset joints and sags, and records where they are. In older Riverside homes it is what separates a line that just needs clearing from one that needs repair.

Main Line

When the Problem Is the Main Line

Several drains are slow or backing up at once
Water rises in the tub or shower when a toilet is flushed
Toilets gurgle when the washing machine drains
A sewage smell outdoors near the cleanout
The same backup returns every few months

Main lines are cleared through a cleanout, a capped pipe usually in the front yard near the house. Some older Riverside homes were built without one, and the line is then reached through a toilet opening or a roof vent, or a cleanout is added. The City of Riverside maintains the sewer mains in the street, and the lateral from the house to the main is generally the owner's to clear and repair. When roots or broken sections keep causing backups, see sewer line repair in Riverside.

Prevention

Keeping Riverside Drains Clear

Keep grease out of the kitchen sink. Wipe pans into the trash and let fats cool in a can.
Do not flush wipes, even ones labeled flushable.
Use strainers in tubs and showers to catch hair.
In a home with roots in a clay lateral, scheduled jetting before the next backup costs less than an emergency call.
Skip chemical drain openers. They rarely clear a main line and can damage old cast iron and the plumber's equipment.

FAQ

Drain Cleaning Questions in Riverside

How much does drain cleaning cost in Riverside?

Clearing a sink or shower drain generally runs $125 to $300, a toilet clog $125 to $275, and a main sewer line $250 to $600. Hydro jetting runs $400 to $1,200 or more. See drain cleaning prices.

Why do roots keep coming back in my sewer line?

Clearing cuts the roots inside the pipe but does not close the joint they came through. In an older Riverside clay lateral they grow back, often within a year. A camera shows whether lining or replacing the damaged section is the lasting fix.

My older Riverside home has no cleanout. Can the main still be cleared?

Yes. The line can be reached by pulling a toilet or through a roof vent, and adding a cleanout makes future service faster and cheaper. The plumber can price it at the same visit.

Who is responsible for the sewer lateral in Riverside?

The City of Riverside maintains the sewer mains in the street. The lateral from your house to the main is generally the owner's responsibility to clear and repair, and repairs need a City of Riverside permit.

Is hydro jetting safe for cast iron pipe?

Usually, when the pipe is sound. On old cast iron and clay, a camera inspection first shows whether the line is too cracked or thin to jet, in which case cable clearing and a repair are the safer path.
