Gas Leak Detection & Repair in Pomona
Pomona is full of historic homes — Lincoln Park, Ganesha Hills, and the Philadelphia corridor have houses dating back to the 1920s, with many original 1930s and 1940s gas piping still in use. Decades of soil shifting, remodeling, and weathering mean these gas lines need close attention. Newer Cal Poly Pomona-area and Fairplex neighborhoods have more modern infrastructure but still benefit from seismic valve retrofits. Regal Plumbing & Rooter, a licensed family-owned plumbing company based at 2141 E Philadelphia St, Suite R in Ontario, CA (CA License #1097482), uses electronic combustible gas detection to pinpoint leaks in 30–90 minutes. Gas leaks are emergencies — same precision detection equipment we use for slab leaks. Serving all of Pomona 24/7.

Gas Line Services
Gas Line Services for Pomona Homeowners
Historic-home gas line re-piping is one of our most-requested Pomona services. Lincoln Park and Ganesha Hills homes from the 1920s, 1930s, and 1940s often have original galvanized gas piping that has reached the end of its safe service life. We replace aging sections, bring everything to current code, and document the work for permit and insurance purposes.
Seismic shut-off valve retrofits are essential in Pomona given proximity to the Chino Fault and the broader San Andreas system. CA SB 1445 mandates them on new construction; for older homes, retrofitting is a smart safety upgrade. The valve trips automatically at roughly a 5.4 magnitude shake.
New gas line installations for BBQs, fire pits, and pool heaters are common around the Fairplex and Cal Poly Pomona neighborhoods. Gas leaks are emergencies — we use the same equipment as our slab leak detection service.
KNOW THE SIGNS
Warning Signs of a Gas Leak in Your Pomona Home
The most obvious sign is the rotten egg or sulfur odor SoCalGas adds. A hissing or whistling sound near a gas line, meter, or appliance signals a pressurized leak. Dead or dying vegetation in older Pomona yards near buried gas runs can indicate an underground leak displacing oxygen in the soil.
Pay attention to your body. Dizziness, nausea, or persistent headaches indoors can mean low-level exposure. An unexplained spike in your gas bill often reveals a slow leak. Visible corrosion on connections is especially common in historic Lincoln Park and Ganesha Hills homes. Professional gas leak detection in Pomona, CA is one phone call away.
EMERGENCY ACTION
What To Do If You Smell Gas in Pomona — Emergency Steps
The moment you detect gas in your Pomona home, your first instinct might be to flip a light or grab your phone — don't. Any electrical spark can ignite accumulated gas. Do not light matches and do not start a vehicle in an attached garage. Leave everything as it is.
Evacuate immediately. Get every person and pet out, leaving doors open to ventilate. Move at least 100 feet away. Call 911 from a cell phone or a neighbor's, then SoCalGas at 1-800-427-2200. Once they have secured the property, call Regal Plumbing at (909) 600-4561. Our 24/7 emergency team dispatches from our nearby Ontario shop.
OUR PROCESS
Our Gas Leak Detection Process in Pomona
Every Pomona gas call starts with an initial safety assessment. Our technician evaluates the area for hazards, checks ventilation, and confirms it is safe. If conditions are unsafe, we coordinate with SoCalGas before entering.
Next we use electronic combustible gas detectors to sweep every line, fitting, valve, and appliance connection — including the original galvanized piping in many Lincoln Park and Ganesha Hills homes. These instruments find concentrations far below what the human nose can sense. Once we identify elevated readings, we pinpoint the exact leak location with no demolition guesswork.
After repair, we run a full pressure test and monitor for any drop before service is restored. Most Pomona detection visits take 30 to 90 minutes.
