Old Pasa Plumbers is the Pasadena emergency plumbing team built around the city's oldest blocks: the brick storefronts, restaurant kitchens, loft buildings and medical offices of Old Pasadena, and the estates and apartments just south and west of it. Founded in 2010 and led by owner Michael Sullivan, our 30 skilled professionals run 10 fully loaded service vans from East Colorado Boulevard, answering burst pipes, sewer backups, failed water heaters and grease emergencies around the clock. We know what a Saturday-night backup costs a business on Colorado Boulevard, and we know how late-1800s plumbing behaves under a modern workload. A person answers the phone at any hour, nothing is replaced until the cause is proven, and the price is yours to approve first.

Under California's food code, a sewage backup or a loss of safe water in a restaurant, café or bar can be an imminent health hazard, and unless it's corrected immediately an enforcement officer can suspend the health permit and order the facility closed on the spot. Inside city limits, that officer works for the Pasadena Public Health Department, which permits and inspects the city's retail food establishments; Pasadena has run its own health department since 1892. A backed-up floor sink at 7 p.m. on a Saturday in Old Pasadena isn't a maintenance ticket. It's a closure risk with a clock on it.
Our first job on a commercial plumbing call is to stop the hazard, protect whatever can safely stay open, and document the fix for the inspector. Each emergency plumbing repair Pasadena restaurants call us for ends with dated photos and an itemized invoice showing what failed and what was done.

Old Pasadena is the city's original commercial center, a district of late-1800s and early-1900s brick buildings that now carry restaurant kitchens, salons, gyms and loft apartments their builders never imagined. The public sewer under these streets is old, too: nearly nine in ten feet of the city's sewer pipe is vitrified clay, and close to a quarter of it predates 1900. Inside the buildings, cast-iron stacks and drains have carried a century of flow, and some storefronts sit over basements below street level.
Pasadena code requires a backwater valve wherever a fixture sits below the curb or property line, because a surcharging street sewer pushes sewage into the lowest opening it can find. Add grease from a busy kitchen, roots at old clay joints and plumbing extended for each new tenant, and a building can go from slow drains to standing sewage in a single dinner rush. Our sewer camera inspection service finds the exact failure point before any work begins.
Our vans work out of East Colorado Boulevard, so Old Town, the Civic Center and the blocks south toward the South Pasadena line are the shortest runs we make. The first hour is about control: stop the water or isolate the drain, protect stock and dining areas, and keep restrooms or a prep line running wherever it's safe to.
After hours is when the 24 hour plumber Pasadena businesses call does its loudest work, whenever the hazard allows: jetting a main line at 1 a.m. instead of during service, and leaving the floor clean for the morning crew. Single-point failures are usually fixed on the first visit; lining a stack or replacing a lateral to the street takes permits and several days.
Snaking a grease-choked line buys a few weeks, because it punches a hole through the blockage and leaves the pipe walls coated. A lasting fix starts with a sewer camera to see what the line is made of and where it fails, then hydro-jetting to scour grease and roots back to bare pipe, then a second camera pass to prove the result.
From there, the repair follows the footage. An undersized or failing grease interceptor gets resized or replaced to a design the city engineer approves, a cracked cast-iron section gets lined or replaced, and a clay lateral with offset joints gets lined, burst or replaced with any section between the curb and the main brought fully up to standard, as PMC 13.24.210 requires. A cleaning interval matched to the kitchen's volume keeps it from coming back.
Most plumbing companies sell the same residential playbook in every city. Old Pasadena doesn't fit it: the Old Pasadena Historic District, listed on the National Register in 1983, spans buildings from the 1870s through the 1940s, and the corner of Fair Oaks Avenue and Colorado Boulevard is the zero point every Pasadena street address counts from. Our vans start a few doors from that corner.
Old Pasa is built around one question: how do you keep a historic building open and safe when its plumbing fails at the worst possible hour? That's why the local plumber Pasadena business owners call puts hydro-jetting, trenchless sewer repair, commercial service and historic re-piping at the center of the work.
Each building type in our part of the city fails in its own way, so every repair starts with knowing what's behind the wall.
Anything below the street is the first thing a surcharging sewer reaches. Pasadena requires a backwater trap or valve wherever an outlet or fixture sits below the curb or property line, installed where it stays accessible and serving only the low fixtures.
Old Town and the blocks around it run on restaurants, bars and hotels, and their plumbing emergencies follow the dinner rush. The emergency plumbing services Pasadena restaurants rely on have to protect the health permit and the night's revenue at the same time.
When one building houses a clinic, three offices and a café, a single failed line can shut down every tenant at once. We isolate the failure so the rest of the building keeps working.
Usually, yes. Health agencies applying the California Retail Food Code list a sewage overflow or backup, the loss of a potable water supply, and water too cool to sanitize utensils among the conditions that can force a food facility to close until they're corrected. Orange County's environmental health office notes that every food facility on a backed-up sewage line can have its permit temporarily suspended. In Pasadena, food facilities answer to the city's own Environmental Health division, reachable at (626) 744-6004, rather than to the county.
The risk reaches staff, too. Sewage carries bacteria and viruses, so cleanup calls for protective equipment, disinfection and disposal of anything porous it touched. As the Pasadena emergency plumbing team on call, our part is to stop the source, clear and film the line, and hand you documentation that supports reopening.
Before hiring anyone for commercial work, check three things on the ad itself. Any emergency plumber Pasadena, California businesses bring in should print a CSLB license number, may only call itself "insured" if it names the coverage, and can't use "bonded" to mean the license bond every contractor posts. Old Pasa is a Class C-36 plumbing contractor carrying commercial general liability coverage.
Pasadena's sewer code puts grease interceptors on the owner: each one must be designed and sized to keep sand, grease and oil out of the public sewer, must hold what it collects, and if the city engineer finds it inadequate must be fixed within 30 days of notice or the building faces disconnection and fines. Water heating is changing as well. South Coast AQMD Rule 1146.2 now requires zero-emission units for many commercial water heaters and boilers up to 2 million Btu/hr, starting with smaller units in new buildings on January 1, 2026 and in existing buildings on January 1, 2029, with larger units following through 2033.
A "Pasadena" address in East Pasadena, Chapman Woods or Kinneloa Mesa is really in unincorporated Los Angeles County, and a business there answers to different agencies. Food facilities there fall under LA County Public Health instead of Pasadena's health department. County rules also put the whole lateral on the owner, out to the main and under the road, parkway and sidewalk, and any dig in the County right-of-way needs a Public Works permit. Even the water can come from a different source: PWP serves part of the area, and smaller providers such as Kinneloa Irrigation District serve others.
When a kitchen is down, owners usually choose between three kinds of help. Here's how they differ, by type rather than by name.
| Company Type | Typical Focus | After-Hours Commercial Response | Grease, Backflow & Below-Grade Work | Historic-Building Experience | Documentation |
|---|---|---|---|---|---|
| Residential-Focused Plumber | Homes first | Often limited late at night | Basic drain cleaning | Varies | Invoice only |
| Regional Facilities Contractor | Large accounts on contract | Routed through a call center | Broad, often subcontracted | Rarely district-specific | Contract reports |
| Old Pasa Plumbers (Us) | Old Town businesses, mixed-use buildings and nearby homes | Live 24/7 dispatch from East Colorado Boulevard | Hydro-jetting, interceptors, ejectors, backwater valves, ASSE 5110 backflow testing | Old Pasadena Historic District buildings | Camera footage, dated photos, itemized invoices |
We built Old Pasa for one part of the city: Old Town's buildings, the businesses inside them and the homes around them.
Old Pasa is owned and led by Michael Sullivan, so there's a name behind every job.
Hydro-jetting and advanced drain cleaning are core specializations, backed by a free camera inspection with sewer drain cleaning.
Lining or bursting where the pipe and ground allow, with $500 off trenchless sewer repair.
C-36 licensed, with an ASSE 5110 backflow tester, IAPMO-certified medical gas technicians and NITC journey-level plumbers on staff.
At about 13 grains of hardness, Pasadena water coats heaters, dishwashers and ice machines, so we size filtration and softening to the equipment.
30 skilled professionals and 10 fully loaded vans, so the 24 hour plumber Pasadena businesses call actually has a crew to send.
If another contractor says the interceptor, stack or lateral has to go, we'll look before you sign.

For a business, the math is mostly about downtime. A restaurant that can't run water or drains may not be allowed to operate at all, and one lost weekend night in Old Town costs more than most repair invoices. Insurance claims and health-department reinspections both run on documentation of what failed, why, and what was done — which a quick DIY fix can't provide.
Street-side lateral repairs also need permits and must meet PMC 13.24.210, and work in an unincorporated area needs a County permit. A fast, documented emergency plumbing Pasadena, CA repair keeps the closure short and the paperwork clean.
Bottom line: To a chain, Old Town is one more ZIP code. To us, it's the district our vans leave from every day.
Every photo in this gallery comes from a real job in or near Old Pasadena: grease-choked mains before and after hydro-jetting, rebuilt backwater valves in basement restrooms, replaced ejector pumps, lined cast-iron stacks and repiped estate homes. Each one is matched to the dated record of the job, so owners, managers and inspectors can see exactly what changed.

Holiday parties fill Old Town's kitchens and restrooms just as winter storms push water into old clay joints, which makes this the busiest stretch of the year for the emergency plumbers Pasadena, CA restaurants rely on. New Year's adds the Rose Parade, which closes Colorado Boulevard straight through the district from 10 p.m. on New Year's Eve until the route is cleaned up the next afternoon.
Spring is the time to finish compliance work before patio season peaks. Backflow assemblies get tested and reported, grease interceptors get checked against the menu you actually run now, and water heaters get serviced before summer demand.
Long hot days fill Old Town's patios and push water heaters, ice machines and dishwashers hard. Pasadena's hard water, averaging about 13 grains per gallon, builds scale fastest in exactly that equipment.
Fall in Pasadena can bring triple-digit heat; an extreme heat warning ran into early October this year followed by Santa Ana winds and the first rain. It's the window to get kitchens and buildings ready before the holidays arrive.
Old Town's blocks were laid out long before service vans, and its alleys and public garages are part of how the district works. Every commercial call is planned around access to the alley door, the loading zone, the nearest public garage such as One Colorado — and around whether the noisy part of the job can wait until after close.
Parade days need their own plan, because our base sits on the route. Colorado Boulevard closes from Orange Grove Boulevard to Sierra Madre Boulevard at 10 p.m. on New Year's Eve and usually reopens around 2 p.m. on New Year's Day, and the Colorado Street Bridge closes at 8 p.m. on December 31. On those nights we route south of Colorado on Del Mar Boulevard and Cordova Street, the east-west streets the city points drivers to.
Prevention costs less than one lost dinner service or one after-hours emergency plumbing repair Pasadena kitchens could have avoided. A short routine, kept on a calendar, does most of the work.
Here's what Old Town owners and managers actually call a Pasadena emergency plumber about, and what each sign usually means.
Floor sinks or floor drains backing up in the kitchen — a blocked main or an overloaded interceptor.
Grease odor in the dining room or alley — an interceptor overdue for service, or a venting problem.
Toilets overflowing on one floor during the rush — a restricted stack or lateral needing camera inspection.
No hot water at the hand sinks — a failed water heater or recirculation problem, and a closure risk for food service.
A pump alarm or water in the basement — a failed ejector or sump pump, or a backwater valve that didn't seal.
Low pressure on upper floors — a failing pressure regulator or corroded risers needing repiping.
Sewage odor in the alley or damp pavement over the lateral — a cracked or separated sewer line.
After each repair you get the footage, a short note on what's urgent and what can wait, and a cleaning or service interval for the line or fixture involved.
Price depends on the hour, the failure, the access and the equipment the job needs: a jetter and camera for a grease-choked main, a pump for a basement ejector, or a permit for street-side work. Market data gives a starting point: Angi's August 2026 figures for Los Angeles show emergency calls from $114 to 568,about193 typical, with nights, weekends and holidays billed at 1.5 to 3 times standard labor, and main sewer line clogs at roughly $1,510 to $5,680.
Our crews quote before they start, and if a job grows, the new number gets your approval first; that's how every Pasadena CA emergency plumber on our team works.
Triage starts while you're still on the line. Tell us what's down and whether food is being served; we'll walk the manager on duty through closing the right valve or taking a fixture out of service, then confirm keys, alarm codes and the fastest way in — the alley door, loading zone or garage.
On arrival, the failed line, fixture or tenant space is isolated so the rest of the building keeps working. Sewage and standing water are contained, stock and equipment are protected, and the areas that can stay open are identified before anything else happens.
Nothing gets replaced on a guess. Kitchen mains and laterals are filmed with a sewer camera, suspected leaks are traced electronically or confirmed at the meter, and supply lines are isolated and pressure-checked, with the footage yours to keep.
Before any work starts, the owner or manager on duty sees the options — clean or replace, line or dig — with a price beside each, and signs off on one.
Most single failures are fixed on the first visit, often after close. Bigger jobs — an interceptor swap, a lined stack, a lateral repair that reaches the street — go on the schedule with City or County permits, are built to the 2025 California Plumbing Code, and pass inspection before we call them done.
The repair is proven with a second camera pass or a pressure test, contaminated surfaces are disinfected, and the dated photos and itemized invoice go into one record that the health inspector, your insurer and your landlord or HOA can all use.
Every emergency plumbing service Pasadena, CA businesses book includes the same six things, whatever the hour.
Old Town and the blocks south of it include condominiums inside historic buildings, such as Castle Green, along with newer mixed-use lofts. Under California's Davis-Stirling Act, unless the declaration says otherwise, the association repairs the common area and is responsible for restoring interrupted water, gas, heat or electrical service that begins in the common area, even when the problem reaches into a unit; each owner handles their own separate interest.
That makes the starting point of a leak the first question in any building dispute, so every emergency plumbing Pasadena, CA call we take in a shared building documents exactly where the failure begins.
Each job file holds the camera footage or photos, the name of the technician and a written scope, enough for anyone to check what was done and when. Old Pasa is owned and led by Michael Sullivan, which means a named owner stands behind every invoice.
Sixteen years in, Old Pasa fields 30 skilled professionals and 10 fully loaded service vans from East Colorado Boulevard as a Class C-36 plumbing contractor. Backflow testing is handled by an ASSE 5110-certified tester, medical gas work by IAPMO-certified technicians, and our plumbers hold NITC journey-level certification.
Most of our night calls fall into these services, listed with commercial work first.
Disruption is mostly a planning problem. Pinpoint the failure first with a camera or leak tracing, and the only floor that gets opened is the one over the break; move the loud work to after close, and the dining room never hears it. Where pipe and ground allow, lining or bursting replaces a lateral without a trench through the courtyard.
Historic buildings get the same care. We protect original tile, terrazzo and woodwork, work from basements and alleys wherever we can, and leave the space ready to open — so the emergency plumbing services Pasadena storefronts receive don't cost them a business day they didn't have to lose.
Straight answers to what Old Town owners, managers and residents ask us most. Don't see yours? Call, and a person picks up at any hour.
Often, yes. A sewage backup can be treated as an imminent health hazard under the California Retail Food Code, and unless it's corrected immediately, an inspector can suspend the permit and close the facility. In Pasadena, food facilities answer to the city's own Environmental Health division at (626) 744-6004.
Pasadena's sewer code. Interceptors must be sized and designed, with the city engineer's approval, to keep grease, oil and sand out of the public sewer and to hold what they collect. If one is found inadequate, the owner has 30 days after notice to fix it or faces disconnection and fines.
At least once a year. California water rules require annual testing by a certified tester, and Pasadena Water and Power runs a Cross Connection Program for its service area at (626) 744-7958. Our ASSE 5110-certified tester handles both the test and the paperwork.
Under California's Davis-Stirling Act, unless the declaration says otherwise, the association repairs the common area and must restore interrupted water service that begins there, even if the problem reaches into a unit. Each owner is responsible for their own unit, so where the leak starts usually decides who pays.
The property owner. Pasadena maintains the main in the street, but the lateral from the building to its connection at the main belongs to the owner, and each building with its own street frontage must have its own connection. Any section replaced between the curb and the main must meet current standards.
Yes, when a fixture sits below the curb or property line. Pasadena code requires an approved backwater trap or valve on the drain serving those low fixtures, installed where it stays accessible, so a surcharging street sewer can't back up into the building.
It depends on the unit. Residential-type gas water heaters still fall under SCAQMD Rule 1121, but many larger commercial water heaters and boilers up to 2 million Btu/hr now face Rule 1146.2's zero-emission limits — for smaller units, from 2026 in new buildings and 2029 in existing ones. We check the rating before quoting a replacement.
Hard enough to matter. PWP's 2026 report shows 2025 hardness averaging about 222 ppm, roughly 13 grains per gallon, with a scale-forming balance. That scale builds fastest in water heaters, dishwashers, ice machines and espresso equipment, which is why filtration or softening is worth pricing out.
Yes. Dispatch runs 24/7, including New Year's Eve and New Year's Day. Colorado Boulevard closes through Old Town from 10 p.m. on December 31, so we route around the parade and schedule non-urgent work before the closure.
