National City is the second-oldest city in San Diego County, so a drain call there can involve old pipe as well as an ordinary clog. The City maintains the sewer mains; the drains in your home and the line to the main are the owner's to keep clear. Call the number on this page to be connected with a local plumber in National City.
What happens when you call
Your call is connected with an independent plumber who works in National City. You will be asked which drains are slow, whether anything has overflowed and whether you know where the cleanout is. At the house, the plumber runs water to watch how the system drains, then chooses an access point. A sink, tub or toilet clog is usually reached through the fixture. A main line plug is opened from the outdoor cleanout, or through a toilet if there is no cleanout. If the same line keeps backing up, a camera can show what is inside.
What the cost depends on
- How many fixtures are affected and where the blockage sits
- Whether the cleanout is easy to reach or buried, painted over or missing
- Whether the line needs cabling only or jetting and a camera pass too
- The condition of the pipe once the plumber can see it
- Whether the visit is during the week or at night, on a weekend or a holiday
Ask for the price to be explained before the work starts and for a heads-up if something found in the line would change it.
National City conditions
Incorporated in 1887, National City has Victorian-era homes among its housing, which means a plumber may meet several generations of drain pipe in the same neighborhood. In older homes, cast iron and clay are more common, and those materials collect scale and invite roots in ways plastic does not.
The City of National City provides sewer service to about 9,000 customers through roughly 105 miles of sanitary sewer main and two pump stations, billed as a flat monthly rate on the property tax bill rather than the water bill. If you think the blockage is in the City's main line, call Engineering & Public Works at (619) 336-4580 on weekdays or National City Police at (619) 336-4411 after hours. Clearing a stoppage is service work, but the City's Building Division requires a plumbing permit for repairs, alterations and fixture replacement when the trap is broken, so if pipe has to be replaced, permit work becomes part of the job.
Checklist before the plumber arrives
- Stop using water if more than one drain is backing up
- Look for the cleanout near the foundation or along the side of the house
- Move stored items out from under the affected sink
- Keep children and pets away from any standing wastewater
- Note what was flushed or poured down recently and when the problem began
