Common questions about plumbing services in Ontario, CA.
To prevent frozen pipes in Ontario, insulate exposed pipes in unheated areas like garages, crawl spaces, and attics. Keep cabinet doors under sinks open during cold snaps. Let faucets drip slightly during freezing temperatures. If a pipe does freeze, call Magnet Plumbing immediately rather than attempting to thaw it yourself to avoid a burst.
If you smell gas in your Ontario home, do not operate any electrical switches, open flames, or appliances. Leave the building immediately, leaving doors open as you go. Call your gas utility from outside or from a neighbor, then call Magnet Plumbing for emergency gas line inspection. Do not re-enter until a professional has cleared the property.
Plumber rates in Ontario typically range from $100 to $250 per hour depending on the type of work and time of day. Common jobs like drain cleaning run $150 to $300, while slab leak repair and repiping projects cost significantly more. Magnet Plumbing provides free estimates so you know the full cost before any work begins.
Most tank water heaters last 8 to 12 years. Consider replacement when your unit is over 10 years old, produces rusty or discolored water, makes rumbling or popping noises, or requires frequent repairs. Magnet Plumbing offers free water heater assessments to help Ontario homeowners decide between repair and replacement.
Burst pipes, gas leaks, sewer backups, and flooding all require immediate emergency plumbing response in Ontario. A burst pipe can release hundreds of gallons per hour, and gas leaks pose fire and explosion risks. Magnet Plumbing provides 24/7 emergency plumbing service throughout Ontario and surrounding California communities.
Low water pressure in Ontario homes is often caused by mineral deposits clogging aerators and pipes, a partially closed shutoff valve, a failing pressure regulator, or a hidden water line leak. Corroded or deteriorated pipes in older Ontario properties can also restrict flow significantly. A licensed plumber can diagnose the specific cause and recommend the right fix.

"Called Magnet Plumbing when our old 40-gallon tank started leaking. They came out the same day, gave me a fair quote on a tankless replacement, and had it running by end of day. Could not be happier with the work or the price."
"Our main line backed up on a Saturday night and the Magnet Plumbing crew showed up within the hour. They cleared it, camera inspected it, and gave us a quote to fix the damaged section. Professional from start to finish."
"We had a slab leak that nobody else could pinpoint. The Magnet team used proper leak detection equipment and found it under the kitchen in about thirty minutes. The repair was clean, no extra damage to the flooring, and the pricing was honest. Highly recommend."
