Van Nuys housing is dominated by 1950s–1970s slab-on-grade single-family homes built during the post-war San Fernando Valley boom. The slab-on-grade construction is the single biggest factor driving plumbing service patterns here — original copper supply lines run inside or just below the concrete slab, and after 50–70 years many of those lines have developed pinhole leaks that show up as warm spots on tile floors or unexplained spikes in water bills. Cast iron drain mains from the same era are now at the end of their service life; we routinely identify holes at the bottom of horizontal runs during camera inspections. Van Nuys also runs the hardest LADWP water in our service area — typically 15–18 grains per gallon from the San Fernando Valley supply — which drives accelerated water heater scale, recirculating pump wear, and noticeable mineral deposition on tankless heat exchangers within 18–24 months without a softener.
Leak detection in Van Nuys is dominated by slab-leak diagnosis. The 1950s–1970s slab-on-grade homes that make up most of the housing here have copper supply lines under the concrete that develop pinholes after 50–70 years of service. We use acoustic listening discs and infrared thermal imaging to localize slab leaks within 6–12 inches before opening any concrete. Pressure isolation testing on the supply manifold tells us whether it’s a hot or cold line, and helps narrow down which fixture branch contains the leak before we make a single saw cut. Beyond slab leaks, Van Nuys homes also generate underground supply line leaks (the run from the meter to the house, often 50–80 feet of buried copper or galvanized) that show up as wet spots in the yard or unexplained water bill increases.
Recent Van Nuys leak detection: a homeowner on Cantlay Street reported a $340 water bill (normally $85) and damp soil between the meter and the house. Used a contact-microphone walkover along the supply path; pinpointed the leak at 22 feet from the meter under a flagstone path. Repaired with a single-section copper splice and a sleeved tunnel rather than digging the full run. Total: $1,180 including bill-credit documentation for the homeowner’s water utility.
