If you smell gas in your Kahului 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.
To prevent frozen pipes in Kahului, 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.
Your main water shutoff valve in Kahului is typically located near the water meter, near the front foundation, or in the basement or utility room. Turn the valve clockwise to close it.

"Magnet repiped our entire house last month. Clean install, finished a day ahead of schedule, and they respected our home the whole time. Worth every penny."
"Smelled gas in the basement late at night and called the emergency line. A plumber was dispatched within the hour, located the leak at a corroded fitting on the water heater gas line, and repaired it on the spot. They even came back the next day to re-verify with the gas detector. Truly appreciated the care taken."
