You’ve found a house in Encino you love. The kitchen’s been updated. The floors are refinished. The landscaping looks great. The general home inspection came back clean. But there’s something the home inspector almost certainly didn’t check — the condition of the sewer lateral, the water supply line, and the drain system beneath and around the house.
Standard home inspections in California cover visible plumbing: they check for active leaks at exposed pipes and fixtures, verify that toilets flush, and confirm that hot water is working. What they don’t do is run a camera through the sewer line, pressure-test the water supply, or assess the condition of buried pipes that are 40 to 70 years old. And in Encino — where the housing stock spans from post-war ranch homes to 1970s hillside builds — those hidden pipes are where the most expensive surprises live.
What a Pre-Purchase Plumbing Inspection Covers
A dedicated plumbing inspection goes beyond the surface-level checks in a general home inspection. Here’s what a licensed plumber evaluates:
Sewer camera inspection. A waterproof camera is fed through the sewer lateral from the house to the city main. The plumber records footage of the entire pipe, noting any root intrusion, cracks, offsets, bellies, corrosion, or collapses. This is the single most valuable piece of information a buyer can get about an older Encino home’s plumbing. We’ve covered the full process and what it reveals in our sewer camera inspection guide.
Water supply line assessment. The plumber checks the material, age, and condition of the main water supply line. Galvanized steel lines in pre-1970s Encino homes are a known replacement liability. Even copper lines in older homes may show signs of corrosion or low-flow conditions. A pressure reading at the main confirms whether the incoming supply and pressure regulation are adequate.
Drain line function test. Running multiple fixtures simultaneously reveals whether the drain system handles volume properly. Slow drainage under load, gurgling, or backflow between fixtures all indicate problems that wouldn’t appear if you only run one faucet during a casual walkthrough.
Water heater condition. The age, type, and condition of the water heater are checked — including signs of corrosion, leaking, or improper installation. A 12-year-old water heater that’s still functional may look fine to a buyer, but a plumber recognizes that it’s near end-of-life and factors that into the overall assessment.
Visible pipe material inventory. The plumber notes the materials used throughout the accessible plumbing system — copper, PEX, CPVC, galvanized, cast iron, ABS, PVC. A house with mixed materials from multiple renovation eras can indicate patchwork repairs that may or may not have been done to code.
What Plumbing Inspections Find in Older Encino Homes
Homes in Amestoy Estates, Encino Village, Hayvenhurst, and Royal Oaks were largely built between the late 1940s and early 1970s. Common findings in these neighborhoods include cast iron drain lines with advanced internal corrosion, clay sewer laterals with root intrusion at every joint, galvanized supply lines with significant flow restriction, original water heaters well past their useful life, and previous repairs that were done without permits.
None of these are deal-breakers necessarily — but they’re all costs. A buyer who knows about them before closing can negotiate a price reduction, request a repair credit, or factor the work into their renovation budget. A buyer who discovers them after closing pays full price for both the house and the repairs.
How Much Does a Pre-Purchase Plumbing Inspection Cost?
A comprehensive plumbing inspection including a sewer camera scope typically runs a few hundred dollars. Compare that to the cost of a sewer line repair (which can run several thousand), a full repipe, or a water damage restoration project, and it’s one of the highest-ROI investments a buyer can make during escrow.
According to the American Society of Home Inspectors, supplemental inspections — including sewer scopes and specialized plumbing assessments — are increasingly recommended for homes over 30 years old. In a market like Encino, where the median home age comfortably exceeds that threshold, it should be standard practice.
Can You Use the Inspection Results to Negotiate?
Absolutely. A recorded sewer camera inspection showing root-infiltrated clay pipe, a pipe belly, or early-stage corrosion is objective evidence that repair work will be needed. Buyers routinely use this footage to request seller credits, price reductions, or pre-closing repairs.
Even if the seller declines to adjust, you’ve still gained essential information. You know what repairs to budget for, you can schedule them on your timeline instead of reacting to an emergency, and you avoid the unpleasant surprise of discovering a $10,000 plumbing problem six months after moving in.
Schedule the Inspection Before Your Contingency Window Closes
In a competitive Encino real estate market, timing matters. Plumbing inspections should be scheduled as early in the escrow period as possible so you have results before your inspection contingency expires. A licensed plumber who’s experienced with Encino properties can typically schedule within a few days and provide a written report with camera footage.
