Leak Detection
Slab leaks under finished floors call for acoustic and thermal locating, so we open only the spot that needs it.

Most Calabasas homes are newer than the Valley tracts below them, but hillside pressure, hard water and slab plumbing still cause trouble. When something leaks or quits, call us at any hour.
Plumbing in Calabasas, in short
Common Calabasas calls are slab leaks under newer homes, failing pressure regulators on hillside lots, tankless water heater descaling, recirculation pump problems in large houses and gas lines for outdoor kitchens. We find the cause first, explain the repair and its typical cost, and work around HOA rules and gate access.
How we cover Calabasas
Calabasas sits along the 101 at the west edge of the San Fernando Valley, between Woodland Hills and Thousand Oaks, where the Santa Monica Mountains begin. Most neighborhoods were built from the 1970s onward, many as planned or gated communities on graded hillside lots. Old Town and the canyons add some earlier homes, including properties on long private drives.
Water here comes from the Las Virgenes Municipal Water District rather than LADWP, and permits go through the City of Calabasas. Many communities also have HOA rules and gate procedures, so tell us about access when you call and we will plan the visit around it.
Homes and pipes
How Calabasas homes are plumbed
- Slab homes from the 1970s onMost homes sit on slabs with copper supply lines underneath, so leaks hide below tile and hardwood until a bill spikes.
- Large houses with long hot runsBigger floor plans mean a long wait for hot water at far bathrooms, which is why recirculation pumps are common here.
- Graded hillside lotsSlopes create pressure differences from street to street and longer sewer laterals that drop steeply to the main.
- Homes along open spaceNeighborhoods near the mountains carry wildfire risk, so working outdoor spigots and a known gas shutoff location matter.
What people call about
The calls we get from Calabasas
Pressure Regulator Replacement
High street pressure on lower lots wears out regulators and stresses fixtures, appliance hoses and heater valves.
See the detailsHot Water Recirculation Pump
Long distances between the heater and the far bathrooms make a recirculation loop one of the most requested upgrades.
See the detailsTankless Water Heater Service
Tankless units are common in newer and remodeled homes, and hard water means they need descaling on a schedule.
See the detailsGas Line Installation
Outdoor kitchens, fire pits and pool heaters all need gas lines sized for the load, with their own shutoffs.
See the detailsSeismic Gas Shutoff Valve
With fire country and active faults close by, many owners want an automatic shutoff at the meter.
See the detailsHillside pressure, slab leaks and access in Calabasas
Water pressure is the quiet problem in hillside neighborhoods. A house at the bottom of a pressure zone can see pressure high enough to shorten the life of every faucet, toilet fill valve and appliance hose. A working regulator and a gauge test once a year protect the rest of the plumbing. If your pipes bang or the heater relief valve drips, check the regulator first.
Slab leaks in Calabasas homes tend to show up under expensive finishes. Rather than open a floor on a guess, we pinpoint the leak with listening equipment and thermal imaging, then compare a spot repair with rerouting the line through the attic. Our article on slab leak warning signs applies here as much as on the Valley floor.
Gated and HOA communities add a step. Give us gate instructions and any work-hour rules when you call, and let the HOA know if we may need to dig in a common area. That way an after-hours emergency visit does not stall at the entrance.
Questions we hear
Questions from Calabasas
Who supplies water to Calabasas homes?
Calabasas is served by the Las Virgenes Municipal Water District, not LADWP. That matters for main shutoff questions and meter issues. Plumbing permits go through the City of Calabasas. Neighbors in West Hills and Woodland Hills are in the City of Los Angeles and use LADWP.
Is a recirculation pump worth it in a Calabasas home?
In a large house where hot water takes a minute or more to reach a far bathroom, usually yes. A pump with a timer or a demand button cuts the wait and the water poured down the drain. The tradeoff is a little electricity and some heat loss in the loop. We size it to your layout.
How do I shut off the gas before a wildfire evacuation in Calabasas?
The shutoff is at the meter, usually on the side of the house. It takes a wrench and a quarter turn so the tab sits crosswise to the pipe. Keep a wrench near the meter. Only shut it off if you smell gas, see damage or are told to by officials, since SoCalGas has to restore service afterward.
What water pressure should a Calabasas house have?
Most homes run comfortably somewhere around 50 to 70 psi at the hose bib. Hillside lots near the bottom of a pressure zone can see far more than that from the street, which is why the regulator matters. A cheap gauge on an outside spigot tells you where you stand, and we can test and adjust it on any visit.
