Extend the life of your new water heater in Sunnyvale by flushing the tank annually to remove sediment, replacing the anode rod every 3 to 5 years, setting the thermostat to 120°F to reduce mineral buildup and tank stress, and inspecting the T&P valve annually.

Real feedback from homeowners who trusted Magnet Plumbing with their plumbing projects.
"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."
"Magnet Plumbing fixed a leaky kitchen faucet and installed a new toilet in the master bath on the same visit. They were in and out in a few hours and cleaned up everything before they left. Will absolutely use them again."
"Late-night leak under the kitchen sink, had someone out within 90 minutes. Stopped the leak, replaced the shutoff valve, and I could finally go back to sleep."
