Plumbing in Los Angeles shows up as a slab leak, a tired bungalow supply line, or a garage water heater that finally rusts through. Many ranches and stucco houses are on concrete, and a hot line can bleed under the floor until one room is warm and the rest of the house looks fine. Raised bungalows hide galvanized pipe in walls that have narrowed for years, so a faucet upgrade becomes a stuck shutoff and a pinhole. Cast iron under those houses scales and bellies until a toilet or a tub drains slowly and then not at all. The fixture is rarely the whole story.
Water heaters live in garages and in exterior closets across the city, where they bake. A failed base or a pan with no drain dumps water onto the slab and toward the house. Angle stops under lavatories seize. Main shutoffs hide behind plants. Tree roots from parkway ficus and other street trees find older sewer laterals in the yard, and the backup shows up in a floor drain or a tub while the kitchen still seems fine. Know which side of the house is suffering before you open a wall.
Hot weather changes the stakes. A seep that would announce itself in a wet climate can travel under a Los Angeles slab all summer with little more than a high bill and a warm tile. Inland houses run more hot water demand and more irrigation tie-ins, and those tie-ins confuse a leak hunt if nobody mentions them. Hard water scales heaters and cartridge valves. If you replace a clogged shower valve and leave a corroded galvanized branch, you will be back in the same wall. Say whether the house is a bungalow with a crawl space or a slab ranch, because the access is the job.
Call with the location of the water. Ceiling, slab, yard, or garage are different paths. Say whether drains are slow in one room or several, and whether you already shut a valve. Mention the water heater, any recent fixture work, and trees over the sewer route. Supply leaks, drain failures, and heater failures are separate conversations, and Los Angeles houses often have more than one of them waiting.
