A burst supply line at 2 a.m., a sewer backing up into the shower pan, a water heater flooding the garage — plumbing emergencies don't wait for business hours, and neither should the plumber you call. Alliance is a family-owned and operated plumbing company based in Fontana, serving homeowners across Los Angeles with same-day emergency plumbing service. Our 24/7 emergency line connects you to a real plumber, we give you accurate pricing upfront, and we fix the problem the first time. CSLB #1119845.
What emergency plumbing service involves
Emergency plumbing is about two things: stopping the damage right now, and diagnosing the actual cause so the failure doesn't repeat. When we arrive at a Los Angeles home, the first move is shutting down the water source — main shutoff, angle stops, or an isolated branch line — and containing any active leak before it reaches drywall, hardwood, or subflooring.
From there we diagnose. Common overnight calls include burst copper or PEX lines, failed water heaters (tank ruptures, leaking T&P valves, pilot and ignition failures on tankless units), toilet stoppages that have overflowed, clogged kitchen or main-line drains, slab leaks under the foundation, sewer backups, and pressure-regulator failures that spike house pressure past 80 PSI.
The tools we carry on an emergency truck reflect that: press tools for copper and PEX repairs, sectional and drum drain machines, hydro-jetter for grease and root-choked lines, a sewer camera for main-line diagnosis, and pressure gauges. A typical single-family emergency call runs 1 to 3 hours from arrival to a permanent, code-compliant repair.

Our emergency plumbing process
- Call the 24/7 emergency line. A dispatcher gets your address, the symptoms, and how much water is moving so we can prep the right truck.
- Shut it down over the phone. If water is still flowing, we walk you through closing the main or the nearest isolation valve while we're rolling.
- On-site diagnosis. We locate the failure — leak, blockage, or component — using cameras, pressure tests, and moisture readings rather than guesswork.
- Upfront written price. You see the repair options and the exact cost before we cut a pipe or pull a toilet.
- Repair or replace. Press-fit copper, PEX, cast iron, ABS, sewer lateral, water heater swap — whatever the fix requires, done to L.A. code.
- Verify the fix. Pressure test, camera the line, run the fixture, or fire the heater and check draft. Nothing gets closed up unverified.
- Clean up and document. We photograph the repair, note what failed and why, and leave the workspace clean.
What emergency plumbing typically costs
Emergency plumbing pricing depends on what actually failed and how accessible it is. A straightforward toilet stoppage or a snake-able kitchen clog is at the low end. A slab leak reroute, a main sewer line replacement, or a middle-of-the-night water heater swap sits at the higher end because of the labor, parts, and permitting involved.
Estimates range based on the fixture or line affected, pipe material (copper, PEX, galvanized, cast iron), whether the sewer needs jetting or spot repair, the water heater's size and fuel type, and how much water damage mitigation is already needed. Every job is quoted with accurate pricing upfront — no surprises after we start. Right now we're running $79 water heater service up to 50 gallons, $150 tankless flush and service, and free estimates on new installations. Call the emergency line for your specific situation and we'll give you a firm number before any work begins.

FAQ
How fast can you get to my house for an emergency?
We offer same-day service and dispatch through a 24/7 emergency line. Call and the dispatcher will give you a realistic ETA based on your Los Angeles neighborhood and current calls.
Do you charge a service fee?
Yes, there is a service fee for emergency dispatch. The fee and the repair price are quoted upfront before any work starts, so you know the full cost before you approve it.
My main line is backing up — do I need a full sewer replacement?
Not necessarily. We run a free sewer camera inspection on qualifying calls so we can see whether it's roots, grease, a belly, or a fractured section. Many backups are cleared with jetting or a spot repair.
Can you replace a water heater the same day?
In most cases, yes — standard 40 and 50 gallon tank units are commonly stocked, and we can source tankless replacements same-day for most Los Angeles addresses.
Do you work on tankless water heaters?
Yes. We diagnose ignition, flow-sensor, and scale-related failures, and we offer $150 tankless flush and service for units that just need descaling and maintenance.
Are you licensed?
Yes — CSLB #1119845. Family owned and operated since 2010.
