Guides put a basic visual plumbing inspection at about $100 to $200, a camera inspection at $300 to $1,100, and a combined visit at $400 to $1,300. The city's own permit inspection is usually folded into the permit fee, and small permits in Torrance can come in under $100. Which applies to you turns on whether you are buying a house, chasing a problem or having work done. Other work we send out sits on our gas and plumbing page.
How much should a plumbing inspection run this year?
HomeGuide splits it by method: $100 to $200 for a visual check, $300 to $1,100 for a camera or video inspection, and $400 to $1,300 for both together. Angi reports a national average near $300 and an overall span of $100 to $1,375. Treat them as guide numbers; only the written quote fixes the price.
| Kind of inspection | Guide range |
|---|---|
| Visual check of fixtures, supply and visible drains | $100 to $200 |
| Camera or video inspection | $300 to $1,100 |
| Visual plus camera combination | $400 to $1,300 |
| Sewer camera, basic scope (HomeGuide) | $125 to $500 |
| Sewer camera, full line (Angi and HomeAdvisor average) | about $995, most jobs $271 to $1,725 |
| Backflow test, one device | $75 to $250 (see below) |
Scope explains the gap. Someone walking a three-bedroom house with a gauge and a flashlight is a short visit. A camera pushed through 80 feet of old clay lateral takes longer and needs a clean-out to enter.
What does a drain camera show, and when does it pay off?
The plumber feeds a sealed lens on a flexible rod into the drain and watches the pipe wall on a screen: cracks, shifted joints, roots, sags, scale. It pays for itself in three cases: a house purchase, drains that repeatedly back up, and before anyone prices a line repair.
For a buyer, a sewer scope is the check a standard home inspection skips, since the buried line is out of sight. A pre-purchase scope runs about $250 to $600 in the guides. Tract houses built after the war around Torrance, Gardena and Lawndale commonly rest on old clay or cast iron sewer lines many decades old, where roots and joint offsets turn up most. A recording gives you something to hand the seller or a repair plumber. Two related methods have their own pages: finding hidden leaks and smoke testing a sewer.
When does Torrance require a plumbing permit, and who inspects it?
Plumbing work on pipes, fixtures, water heaters and sewer lines is permitted work in Torrance, and the city inspects it. The plumber normally applies and books the visits, which generally cover a rough stage ahead of closing walls, then a final. Torrance Municipal Code section 81.2.2 lists the work that is exempt, so ask Building and Safety if you are unsure.
Inspections come with the permit, not as a separate booking. The city's FAQ says fees vary with the type and value of the work and that small permits can cost under $100. Card payment adds 2.5 percent. The Building and Safety line is (310) 618-5910; heater swaps, repipes, gas line work and sewer repairs all sit in the permitted group. One worked example is in permits for water heaters.
How do I apply for a plumbing permit online in Torrance?
Create an account in the city's Citizen Access Portal, choose the Plumbing Permit link, and upload the application with any plans or zoning clearance the job needs. Trade permits are applied for separately from building permits. The city accepts permit submittals and plan reviews only electronically.
Most homeowners never touch the portal, because the plumber files. A homeowner is allowed to pull an owner-builder permit for their own primary residence, per the city's FAQ, but then you are responsible for the work passing. Work worth $1,000 or more, parts included, needs a contractor holding a state license in California; the CSLB site has a lookup. Permit expiry rules vary, so ask the city how long a permit stays valid and what happens if work stalls.
Is a backflow test part of this, and what does it cost?
It is a test of a specific device, not a general inspection. A backflow device, found on lawn irrigation, fire lines and some commercial connections, is tested annually by a qualified tester, usually for $75 to $250 per device. The device protects drinking water from reverse flow, so the test is a safety record, not a repair.
Not every house has one. If yours does, your water supplier sends a notice and wants a report on its form. Price depends on device size, access and whether it passes. Repair and replacement ranges are in the backflow testing price guide, and the test itself is described under backflow prevention testing.
How do I compare two inspection quotes?
Line up what each covers: time on site, a recording or written report, how many drain lines, whether any of the fee comes off a repair, and whether cleanout access is included. A cheap quote that ends at the first cleanout buys less than a full-line scope.
Ask too who reads the picture. A camera operator and a plumber who can price the fix are different people. For a purchase, find out whether the findings come as a plain summary you can pass to your agent. To ask for a written price, send the quote form.
Common questions
Does a home inspection include the plumbing?
A general home inspection looks at visible plumbing: fixtures, supply pipes, the water heater and any leaks. It does not scope buried sewer lines. That requires a separate camera inspection, which is why buyers often order one. Ask your inspector what is excluded before closing.
How much of my morning does it take?
For a visual check, budget an hour or two in a typical house. One drain line with a convenient cleanout can be scoped in under an hour. Put both together with a written report and the visit grows, and awkward access adds more.
Can I get the inspection credited toward repairs?
Many plumbers credit the visit fee when you go on to hire them for the repair, but not all do. Ask when booking. A separate inspector who recommends work without doing it has no such credit, though their report is independent and can be used to get several repair bids.
Does a city inspection replace a plumber's check?
No. The city inspector checks that permitted work meets code and signs it off. A plumber's inspection is something you buy to learn the state of your pipes. Neither stands in for the other, and a plumber's report cannot clear a permit.
Should I inspect before buying an older house?
For a house with decades-old pipes, usually yes. A sewer scope plus a look at supply pipe and the water heater runs a few hundred dollars and can expose repairs worth thousands. The guides say a scope finding can also support a request for a repair credit or a lower price.
Prices are one part of the job: plumber torrance covers the rest.
