North Hills combines postwar single-family streets with a large share of apartment buildings along Sepulveda Boulevard. Drain clogs, shared water heaters and aging supply pipe keep us busy here.
Plumbing in North Hills, in short
In North Hills, frequent calls include kitchen and main drain clogs, apartment building stack and lateral problems, water heater failures, galvanized pipe losing pressure and leaking shutoff valves. We diagnose on site, explain options and typical price ranges to owners and managers, and coordinate shutoffs so tenants lose water for as little time as possible.
How we cover North Hills
North Hills, known as Sepulveda until the early 1990s, sits east of the 405 between Granada Hills and Panorama City. Sepulveda Boulevard, Plummer Street and Roscoe Boulevard carry most of the traffic, and the large VA medical campus is on the south side. Single-family homes fill the side streets, while apartment buildings line the boulevards.
Postwar homes here have the same aging copper, galvanized and clay pipe as the rest of the Valley. The apartment stock adds another layer: shared mains, shared sewer laterals, central water heaters and long drain stacks in two- and three-story buildings. A clogged stack can back up into several ground floor units at once, so clearing the right line fast matters.
Homes and pipes
Homes and buildings in North Hills
- Postwar single-family homesSide streets hold modest 1950s homes on slabs with copper or galvanized supply. Many still have original drains and laterals.
- Two- and three-story apartmentsBuildings along Sepulveda and Plummer share stacks, mains and laterals. One failure can affect a whole building.
- Central water heaters and boilersApartment buildings often run large shared heaters or boilers. When one fails, every tenant on that system loses hot water.
- Older galvanized supplySome homes and older buildings still carry galvanized steel. Rust narrows the pipe until upper floors and far units lose pressure.
What people call about
Plumbing calls North Hills owners and managers make
Drain Cleaning
Grease in kitchen lines and wipes in toilets cause frequent clogs in multifamily buildings.
See the detailsWater Heater Repair
Shared heaters work hard, and failed thermostats, burners and anode rods are common repairs.
See the detailsWhole-House Repiping
Galvanized supply in older buildings eventually loses enough pressure that patching stops making sense.
See the detailsHydro Jetting
Grease-coated building drains and main lines need jetting to clean the full pipe wall.
See the detailsBackflow Testing
Buildings with irrigation or commercial service need yearly backflow tests to stay in line with LADWP rules.
See the detailsPlumbing work in occupied North Hills apartment buildings
Most apartment plumbing work happens with tenants at home, so planning matters as much as the repair. We start by mapping the valves: which unit each one feeds, which ones close and which ones are frozen. Buildings that rely on one main shutoff for everything turn a small leak into a building-wide outage.
When we replace a failed valve or add branch shutoffs during a repair, later jobs affect fewer people. For repipes, we work stack by stack so only a few units are without water at once, and we restore service each evening. Owners often schedule shared heater replacements the same way, swapping one unit at a time on buildings with two heaters.
Pricing for North Hills multifamily work varies widely by building size. Clearing a main building line usually runs around $350 to $900, and jetting a grease-heavy main runs about $600 to $1,500. Those are typical ranges, not a quote, and access, cleanout locations and line length change them. For yearly testing details, see our guide to the annual backflow test.
Questions we hear
Questions from North Hills
How do you handle a sewer backup in a North Hills apartment building?
We find the lowest point where sewage is coming up, clear the line from the closest cleanout, then camera the line to find what caused it. Grease, wipes and roots are the usual causes. We tell the manager which units drain into that line, so tenants can be warned to hold off on running water until it is clear.
Is a whole-building repipe practical for an older North Hills apartment building?
Often, yes. We repipe one stack or wing at a time, opening small sections of wall in each unit and restoring water every evening. Copper and PEX both work, and the job runs under an LADBS permit. It takes longer than a house repipe, but it ends the cycle of leaks, weak pressure on upper floors and rusty water.
What does a single-family homeowner in North Hills usually call about?
The usual list is slow drains, water heater replacements, leaking valves and pressure loss in galvanized lines. Homes here are often near the end of their original pipe. We look at the whole system on the first visit and tell you which items are urgent and which can wait. If roots are involved, a lateral camera check tells us more.
