Frequently Asked Questions About Water Heater Replacement
Explore answers to common questions about water heater replacement costs, installation timelines, and system selection in La Puente, CA.
How do I know if I need a replacement or just a repair?
A water heater requires replacement when the steel tank fractures or leaks, internal corrosion produces rusty water, the unit exceeds 10 to 12 years of age, or repair costs approach 50% of a new system's value. Isolated thermostat or element failures qualify for repair.
How long does water heater replacement take?
A standard tank-for-tank replacement takes 3 to 5 hours, including draining, hauling the old unit, installing the replacement, and testing connections. Converting from a tank to a tankless system requires 1 full working day.
What size water heater does my home need?
Homes with 1 to 2 occupants typically require a 30 to 40-gallon tank. Homes with 3 to 4 occupants require a 50-gallon tank. Larger households with 5 or more occupants require a 75-gallon tank or a continuous-flow tankless system.
Should I switch from a tank water heater to a tankless system?
Switching to tankless is ideal if you frequently deplete hot water, seek to reduce monthly energy bills by up to 30%, or want to reclaim floor space. Our plumbers evaluate your gas supply line and venting to ensure tankless compatibility.
What is the average lifespan of a new water heater?
Modern storage-tank water heaters last 8 to 12 years with annual maintenance. High-efficiency tankless water heaters last 20 years or longer when descaled annually.
Do you remove and dispose of the old water heater?
Yes. Every replacement project includes disconnecting, draining, safely removing, and transporting the old water heater to an authorized metal recycling facility.
Are permits required for water heater replacement in La Puente?
Yes. The City of La Puente requires plumbing permits and safety inspections for water heater replacements to verify proper seismic strapping, temperature relief discharge piping, and combustion venting.
What is the difference between gas and electric water heater replacement?
Gas replacements require gas flex line connections, draft hood alignment, and combustion testing. Electric replacements require dedicated 240-volt high-amperage electrical wiring, circuit breaker verification, and immersion element continuity checks.
Why are earthquake seismic straps required in California?
California plumbing code mandates two heavy-gauge seismic straps anchored into structural wall studs to prevent the heavy, water-filled tank from tipping over during seismic tremors, rupturing gas lines and causing fires.
Can a leaking water heater tank be repaired without replacing it?
No. Once the inner glass-lined steel tank fractures or rusts through, it cannot be welded or patched safely under pressure. A tank body leak always necessitates complete unit replacement.
What is an expansion tank, and do I need one?
A thermal expansion tank absorbs excess water pressure created when water expands as it heats inside a closed plumbing system. California code requires expansion tanks whenever backflow preventers or pressure-reducing valves exist.
