A supply line lets go at 11 p.m. A main sewer backs up into the downstairs shower. The water heater dumps forty gallons across the garage floor. When that happens in a Pasadena single-family home, you don't need a sales pitch — you need someone who shuts the water off, finds the actual cause, and quotes a flat price before touching a wrench. That's Alliance. We're family owned and operated since 2010, licensed under CSLB 1119845, with over 40 years of combined trade experience and an emergency line answered 24/7.
What emergency plumbing service involves
An emergency call starts with containment. We locate and close the nearest shutoff — fixture stop, water heater cold inlet, or the main at the meter — so the damage stops growing while we diagnose. Then we find the real source. That might mean pulling a toilet to clear a stoppage at the closet flange, running a camera down the sewer lateral to see whether it's grease, roots, or a bellied clay section, or pressure-testing a suspected slab leak instead of guessing at it.
From there the work depends on what we found. Common Pasadena emergencies include burst copper or PEX supply lines, failed water heater T&P valves and tank ruptures, main line stoppages that back up every drain in the house at once, clogged kitchen drains packed with grease, and hidden water leaks under slabs or behind walls. We carry drain machines and hydro-jetting equipment, sewer cameras with locators, press and sweat fittings, shutoff valves, supply lines, and common water heater parts on the truck so most calls finish in one visit.
Before any of it starts, you see a flat price and approve it. No mystery invoices, no hourly meter running while we work.
Why Alliance for emergency plumbing service
- 24/7 emergency line and same-day service. Our emergency line is answered around the clock; office hours are Monday–Friday 8am–4pm and Saturday 8am–2pm.
- Flat price approved before we start. Accurate pricing upfront, in writing, with no surprises added at the end.
- Diagnosed correctly, solved the first time. We camera the sewer and test the line rather than patching a symptom and coming back next month.
- Family owned and operated since 2010, CSLB 1119845, with over 40 years of combined experience across Southern California.
- One licensed team for the whole house — plumbing, sewer, water treatment, heating, air and electrical — so a plumbing emergency that turns out to be an electrical or water heater issue doesn't need a second contractor.
- Free sewer camera inspection and year-round senior and veteran discounts.
Our emergency plumbing service process
- Call the 24/7 line. Tell us what you're seeing and where the water is going. If it's actively flooding, we'll walk you through finding your main shutoff on the phone.
- Same-day dispatch. We send a licensed technician to your Pasadena address with the drain machines, camera, and repair parts the described symptom calls for.
- Contain and diagnose. Water off at the correct isolation point, then a real diagnosis — camera inspection for sewer and drain issues, leak location for wet drywall or slab symptoms.
- Flat price, your approval. We show you what we found, explain the repair options, and give you one flat number. Nothing proceeds until you say yes.
- Repair on the spot. Most stoppages, burst lines, failed valves, and water heater repairs are completed on the first visit.
- Test and verify. We restore pressure, run the fixtures, re-camera the line where relevant, and confirm the problem is actually gone.
- Walk the house with you. We show you the shutoffs, flag anything nearby that's about to fail, and leave the work area clean.
What emergency plumbing service typically costs
Emergency plumbing estimates range based on what's actually wrong, how accessible it is, and how much of the system the failure touches. A toilet stoppage or a single clogged drain sits at the low end. A main line stoppage that needs hydro-jetting, a slab leak that has to be located and rerouted, or a water heater replacement sits considerably higher because of the labor, materials, and access work involved.
The factors that move the number: whether the line can be reached from an existing cleanout or one has to be installed, pipe material and age, whether drywall or concrete has to be opened, fixture and valve quality, and the time of day. What's included is the diagnosis, the flat quoted repair, and testing afterward. Not included is drywall finishing, flooring, or restoration work after a major leak.
We charge a service fee, we tell you what it is before we roll, and you approve the flat repair price before any work begins.

FAQ
Do you really answer the phone at 2 a.m. in Pasadena?
Yes. Our emergency line is staffed 24/7. Our office hours are Monday–Friday 8am–4pm and Saturday 8am–2pm, but plumbing emergencies don't keep office hours and neither does our dispatch line.
Can you come out the same day?
Same-day service is standard for us on emergency calls. Call the line, describe the problem, and we'll give you a realistic arrival window rather than a vague "sometime today."
How do I know what it'll cost before you start?
We diagnose first, then hand you one flat price for the repair. You approve it before we begin. There's a service fee for the visit and we tell you that number on the phone — no mystery invoices at the end.
My whole house is backing up. Is that a sewer problem?
Usually, yes. When every low fixture backs up at once, the blockage is typically in the main sewer lateral rather than a single branch drain. We run a camera down the line to confirm whether it's roots, grease, or a broken section before recommending anything. The camera inspection is free.
Do you handle water heaters during an emergency call?
We do. Leaking tanks, failed T&P valves, no hot water, and tankless faults are all part of our emergency work, and we carry common parts on the truck.
My water pressure dropped suddenly — is that an emergency?
It can be a sign of a hidden leak or a failing regulator. Our guide on why water pressure drops in summer and how to fix it covers the common causes. If pressure drops along with wet spots, a running meter, or a jump in your bill, call us — that's a leak, not a nuisance. If you're heading out of town, our notes on preparing your plumbing before a vacation can keep a small drip from becoming a flooded house.
