Expert Water Heater Installation

Right-Sized, Code-Compliant Setups

Marlin Plumbing designs and installs water heaters that match your household’s hot water demand, fuel type, and efficiency goals. We assess fixture counts, simultaneous-use patterns, recovery expectations, and space constraints to recommend the best system—high-efficiency tank, tankless, or heat pump—along with proper venting, gas sizing, electrical requirements, and recirculation options for faster hot water at distant taps.

Our licensed installers handle permits, code compliance, and safety from start to finish, including expansion tanks, drip pans with drains, seismic strapping, and condensate management for condensing units. We pressure-test connections, verify combustion/venting, set safe temperatures, and register warranties so your new system is efficient, safe, and protected on day one.

Fast Fault Isolation And Fixes

When your hot water runs out, fluctuates, or takes too long to recover, Marlin Plumbing performs targeted diagnostics to find the root cause. We test electrical components with calibrated meters, inspect gas pressures and flue draft, evaluate thermostats and controls, check anode condition, and look for sediment buildup, crossovers, and dip-tube failures that can reduce output and efficiency.

Our technicians repair both tank and tankless systems, including igniters, gas control valves, thermocouples, heating elements, thermostats, T&P valves, circulators, flow sensors, and heat exchangers. We carry common OEM parts for faster fixes, provide clear estimates before work begins, and offer safety checks to prevent leaks, scalding, or combustion issues from recurring.

Extend Lifespan, Boost Efficiency

Annual maintenance keeps your water heater efficient, safe, and within manufacturer warranty terms. For tank models, service typically includes sediment flushing, anode rod inspection or replacement, T&P valve testing, expansion tank pressure verification, leak checks, and thermostat calibration to a safe 120°F for energy savings and scald protection.

Tankless systems benefit from descaling to remove mineral deposits, cleaning inlet screens, verifying flow rates, checking condensate neutralizers and venting, and updating control settings to maintain peak performance. These steps restore heat-transfer efficiency, reduce error codes, and improve reliability under heavy demand.

Preventive care lowers utility bills, extends equipment life, and reduces emergency breakdowns. We also test water quality and hardness, recommend mitigation (such as softening or filtration) when needed, document all service for warranty purposes, and schedule convenient reminders so maintenance never gets missed.
