24-Hour Emergency Plumber in Aliso Viejo, CA
Licensed & Insured | Upfront Pricing | Available 24/7
Most emergencies in Aliso Viejo trace to one fact: the entire city was built in a tight window in the early 1990s. Original copper supply lines, original water heaters, and original gate valves are all reaching end of life within a few years of each other. When we get an emergency call about a burst pipe or a water heater flood here, it's rarely a surprise — the home was on a timeline.
Most plumbing emergencies are manageable once you know what to do. We're here day, night, weekend, holiday — same team, same pricing, no surprises.
Here's what you need to know.
Is This a Plumbing Emergency?
Not everything needs an emergency call. Some things can wait until morning. Here's a quick way to tell.
Call Right Away
- Water is actively flowing and you can't stop it
- Sewage is backing up into your home
- You smell gas anywhere in the house
- A pipe has burst, you can hear it or see water coming through walls, ceiling, or floors
- Your water heater is leaking heavily or making popping sounds
- A toilet is overflowing and won't stop after the valve is closed
- There's standing water in your home that's spreading
Can Probably Wait Until Morning
- A slow drip from a faucet or under a sink (put a bucket under it)
- A toilet that runs but still flushes
- Low water pressure that's been gradual, not sudden
- A water heater that's producing lukewarm water but not leaking
- A single slow drain (try to avoid using that fixture until we can look at it)
When in doubt, call. We'll tell you honestly whether it needs immediate attention or whether it's safe to wait.
What to Do Right Now
Find your main water shut-off valve and turn it off
Check the garage, front exterior wall, or near the water heater. If seized, turn off at the meter at the curb.
Relieve pressure by opening a faucet
Open a faucet at the lowest point in the house to drain remaining water from the lines.
Move belongings away from the water
Furniture, electronics, personal items. The faster you get things out of standing water, the less damage.

Common Emergencies
Burst or Leaking Pipe
Aliso Viejo is one of Orange County's youngest cities, and that actually tells us a lot about what we find when we get the call. Nearly every home here was built between the late 1980s and early 2000s, which means the entire community's plumbing is aging on the same timeline. The original copper supply lines are now 25 to 35 years old, right at the point where pinhole leaks start showing up. The moderately hard water from South Coast Water District — typically in the 10 to 14 grains per gallon range — has been working on those copper walls for decades, and we're seeing the first wave of failures across the community.
Sewer or Drain Backup
Sewer backups in Aliso Viejo tend to follow the geography. Properties adjacent to Aliso and Wood Canyons Wilderness Park — and there are quite a few of them along the eastern and southern edges of the community — deal with root intrusion from the mature vegetation along the canyon edges. Those root systems follow moisture right into the sewer lateral joints, and once they find a way in, they grow until the line is restricted or blocked.
Water Heater Failure
Water heater emergencies in Aliso Viejo come in waves, and we're in the middle of one right now. A home built in 1993 that's still on its original water heater is sitting on a 33-year-old tank. Even homes that replaced theirs 12 to 15 years ago are now approaching the end of that second unit's expected lifespan. The hard water puts extra stress on heating elements, anode rods, and tank linings, and sediment builds up faster than in softer-water areas.
Gas Smell or Suspected Gas Leak
Gas leaks in Aliso Viejo homes are less common than water-related emergencies, but we see them periodically — especially with aging gas appliance connections, corroded flex lines, and during outdoor kitchen or fire feature installations where the original gas line sizing wasn't designed for the added load. Many homeowners in the community have added outdoor living features over the years, and the gas infrastructure in a 1990s home wasn't always sized with those additions in mind. We're licensed for gas line work and can get everything tested and back up safely.
Why Aliso Viejo Homes Produce the Emergency Calls They Do
Aliso Viejo has a plumbing story that's different from most of Orange County, and it comes down to one thing: the entire city was built in a concentrated window. The Mission Viejo Company and other developers built this community from the late 1980s through the early 2000s, and it was incorporated as a city in 2001. That timeline means the pipes, water heaters, sewer connections, and fixtures across almost every neighborhood are all the same generation.
We're now in the window where that first generation of plumbing is reaching its service life. Copper supply lines approaching 30 to 35 years old. Original water heaters long past their expected lifespan (and many second-generation units approaching the end of theirs). Sewer laterals that have been handling decades of use. This isn't a handful of aging homes scattered across the city — it's the entire community hitting the same milestones at the same time.
The construction mix matters too. Aliso Viejo has a much higher proportion of townhomes, condos, and attached units than most Orange County cities. That shared-wall construction means a plumbing emergency in one unit can affect the neighbor — a burst supply line in an upstairs unit becomes a ceiling leak downstairs. We've handled these multi-unit situations many times here and understand both the technical coordination and the HOA communication that comes with it.
The canyon-adjacent properties along the Aliso and Wood Canyons Wilderness Park boundary add root intrusion to the mix. And the slab foundations throughout the community mean some plumbing runs are embedded in or under the concrete — making leak detection equipment essential before opening anything up.
None of this is unusual for a planned community of this era. It just means that knowing the patterns matters, and we've been inside enough of these homes to recognize them quickly. That familiarity helps us respond faster and get to the right diagnosis on the first visit.
What Happens When You Call
A real person answers the phone. We don't use an answering service.
We dispatch from our Lake Forest location — about 15 to 25 minutes from most Aliso Viejo neighborhoods depending on time of day. We're familiar with the gated communities here and the AVCA-governed properties, so access isn't a delay.
When we arrive, we assess the situation, explain what we're seeing, and give you an upfront price before any work starts. Same pricing whether it's a Tuesday afternoon or a Saturday night.
We carry the parts and equipment to handle most emergencies on the first visit. If the situation needs a bigger solution — a full repipe, a sewer line replacement, a water heater swap — we'll get you stabilized that night and schedule the permanent fix.

“I’m so pleased and so thankful for how quickly and efficiently the crew worked, to get my water back on. We did a whole house repipe and I was dreading the experience, but to my pleasant surprise, it got completed without a hit hitch.”

“Olsen's crews are fantastic. Have used them multiple times now, most recently to get a tankless water heater and water softener. They sent two sets of two plumbers out the day after Christmas, in the rain to get everything installed before the end...”
