Quick Answer
A slab leak in Pomona, CA is a water line leak beneath your concrete foundation, typically caused by aggressive soil chemistry and aging copper pipes in 1950s–1960s homes.

Regal Plumbing & Rooter provides licensed slab leak detection across Lincoln Park, Ganesha Hills, and the Fairplex area with same-day service.
Know the Signs
Warning Signs of a Slab Leak in Pomona Homes
The first sign Pomona homeowners notice is a higher water bill. Next comes the faint sound of running water with all fixtures off, warm spots on tile floors, and damp baseboards. In older Lincoln Park and Ganesha Hills homes, you may also see visible cracking in plaster walls and uneven floor settling as water erodes the soil beneath the slab.
If you live in Pomona and notice these signs, call us before the leak undermines your foundation.
Advanced Technology
How We Detect Slab Leaks Without Tearing Up Your Floor
Regal Plumbing & Rooter, a family-owned plumbing company based at 2141 E Philadelphia St, Suite R in Ontario, CA, uses electronic amplification and acoustic listening equipment to hear water escaping from a copper line through inches of concrete. We pinpoint leaks under your Pomona home within a few inches.
Pressure testing isolates whether the leak is on the hot or cold side, and thermal imaging cameras map temperature differences across your tile. The result is a 1–2 hour diagnosis, a small repair area, and minimal disruption.
Local Conditions
Why Slab Leaks Are Common in Pomona, CA
Pomona's soil profile includes pockets of aggressive chemistry, particularly near the Fairplex and the older neighborhoods around Cal Poly Pomona, that accelerate copper corrosion from outside the pipe. Lincoln Park and Ganesha Hills 1950s–1960s slab homes are still on original copper supply lines, which means many are now 60+ years old and well past their typical service life.
The expansive clay soil that runs through much of Pomona swells 3–5% with seasonal moisture and stresses rigid copper inside concrete slabs. Installing a water filtration and softener system slows interior corrosion and is one of the best long-term defenses against future slab leaks.
Don't Wait
What Happens If You Ignore a Slab Leak in Pomona
An undetected slab leak can waste 250+ gallons of water per day. In older Pomona neighborhoods that already have settling history, that water accelerates the existing problem and can lead to cracked plaster walls, uneven floors, and stuck doors within months. Foundation repairs routinely run $10,000–$30,000.
Standing moisture under your home also breeds mold. Whether you need emergency plumbing or just a professional inspection, acting fast in Pomona saves money. Contact us today.
