Dependable Water Heater Repair And Replacement
Serving Collin County, Dallas County & Surrounding Areas
Comprehensive Water Heater Services
Diagnose, Repair, And Replace Any Water Heater
Mega Toilet Plumbing LLC delivers full-service water heater expertise for traditional tank, tankless, hybrid, gas, and electric systems. Our licensed plumbers arrive in fully stocked vehicles, run precise diagnostics, explain findings in plain language, and provide clear, upfront pricing for repairs or replacement—all backed by strong warranties.
From no hot water and fluctuating temperatures to leaks, rumbling tanks, and discolored water, we pinpoint root causes and fix them right the first time. We service thermostats, heating elements, thermocouples, igniters, gas control valves, anode rods, expansion tanks, and more, and we perform safety checks on T&P valves, venting, combustion, and electrical. When replacement is the smarter choice, we install to current code and offer 24/7 emergency service.
Transparent Guidance And Upfront Options
Deciding between repair and replacement depends on age, condition, efficiency, and safety. Tanks often last 8–12 years (tankless 15–20); rust in hot water, repeated component failures, rising energy bills, or leaks at the tank body typically signal replacement. We compare costs, remaining service life, and energy savings so you can choose with confidence.
If replacement is best, we right-size your system for household demand using first-hour rating (tanks) or flow rate in GPM (tankless), confirm fuel and venting requirements, and address code items like drain pans, seismic strapping, expansion tanks, and proper discharge lines. Expect neat workmanship, permits where required, haul-away of the old unit, and clear manufacturer and labor warranty coverage.
High-Efficiency Tanks And Tankless Solutions
Our installation process prioritizes safety, performance, and longevity. We protect your home, isolate utilities, drain and remove the old unit, and set new equipment with correct venting, gas sizing, electrical connections, and T&P discharge routing. Every job includes leak checks, combustion analysis (for gas), CO safety testing, and commissioning of controls for optimal operation.
Choose from high-efficiency storage tanks (UEF-rated), condensing tankless systems for endless hot water and lower operating costs, or heat pump water heaters for exceptional efficiency. We outline pros and cons, space and venting needs, recirculation options for faster hot water, and potential rebates or incentives to help maximize value.
Routine maintenance protects your investment: annual tank flushing, descaling for tankless units, anode rod inspection, expansion tank pressure matching, and setting temperature to 120°F for safety and efficiency. We also address water quality with scale mitigation to reduce sediment buildup and extend system life.
