Frequently Asked Questions

A comprehensive whole-home plumbing inspection in Southern California typically ranges from $250 to $500. This “Diamond-level” audit from MKR Plumbing includes a high-definition sewer camera scan, water pressure testing, and a full shut-off valve safety check to prevent future emergencies.

The most common signs of a slab leak include an unexplained spike in your water bill, warm spots on your flooring, or the sound of running water when all faucets are off. Because of the expansive clay soil in the Inland Empire and Orange County, foundation shifts often cause these hidden leaks in copper piping.
Yes, tankless water heaters are highly efficient for Southern California homes because they provide endless hot water and only heat water on demand, saving up to 34% on energy costs. At MKR Plumbing, we recommend models specifically designed to handle the mineral content (hard water) common in our local water supply.
Water pressure above 80 PSI is considered dangerous and can cause pipe bursts, leaking faucets, and damage to appliances like water heaters and dishwashers. Many cities in Southern California have high-pressure main lines, which is why MKR Plumbing installs and tests Pressure Reducing Valves (PRVs) to keep your home at a safe 50-60 PSI.
Drain snaking “pokes a hole” through a clog to restore flow, while hydro jetting uses high-pressure water to scrub the pipe walls clean of grease, minerals, and tree roots. For Southern California homeowners dealing with recurring backups, hydro jetting is the superior, long-term restorative solution.
Yes, MKR Plumbing specializes in trenchless sewer replacement, which allows us to install a new pipe using only two small access points. This “no-dig” technology preserves your expensive landscaping, pavers, and driveways in cities like Chino Hills and Yorba Linda while providing a root-proof, 50-year solution.
The primary indicator of a gas leak is a “rotten egg” smell (mercaptan), but you may also notice a hissing sound near gas lines or dying vegetation in your yard. If you suspect a leak, evacuate immediately and call MKR Plumbing for professional gas leak detection and certified repair.

While requirements vary by city, many Southern California municipalities (including Los Angeles and surrounding areas) require Seismic Shut-off Valves during home sales or major renovations. These valves automatically cut off your gas supply during a 5.4+ magnitude earthquake to prevent fires.

Liquid drain cleaners often fail to reach the source of the clog and can actually corrode your pipes over time. In Southern California, recurring clogs are usually caused by invasive tree roots (like Ficus or Palms) or hard water scale, both of which require professional rooter service or hydro jetting to resolve.
We offer same-day and emergency service throughout our primary service areas, including Fontana, Rancho Cucamonga, Riverside, and Ontario. Our central location allows our technicians to respond quickly to plumbing, gas, and sewer emergencies across the Inland Empire.
