Standard Gas Water Heater Replacement in San Diego
Most homes in San Diego rely on a conventional tank-style gas water heater. We expertly remove your old unit, inspect the existing gas and water lines, and install a new, energy-efficient model. Our service includes proper venting setup and ensuring all connections are leak-free and secure. We work with various tank sizes to match your household's hot water demand, balancing efficiency and longevity in your local climate.
Power Vent Water Heater Replacement in San Diego
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails repeatedly, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve difficult placement problems.

For reliable Rheem gas water heater replacement in San Diego, CA, trust FKM Plumbing. Rheem offers a wide range of models, from standard tanks to high-efficiency options, suited for various household needs. Our experts guide you through the selection process and perform a professional installation. We follow all local codes and set the unit up for strong performance and safety for years to come.
Standard Vent Gas Water Heater Replacement in San Diego
Many homes in San Diego rely on standard atmospheric vent gas water heaters. When these units reach the end of their lifespan, typically 10 to 12 years, we provide professional replacement. Our service includes safely disconnecting the old unit, installing a new, energy-efficient model, and connecting it properly to your existing natural gas line and flue venting system. We also check for adequate combustion air and perform a thorough leak test for safety and efficiency.
Large Capacity 75 Gallon Gas Heaters in San Diego, CA
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model. These heaters use larger burners, sometimes 75,000 BTU, and may need a bigger gas line and flue. We check your meter and pipe size to make sure the larger tank gets the gas it needs. A high-recovery unit can be a good middle ground when space is limited. We walk you through recovery rates so you pick the right fit.
