Not professional plumbing advice
The content on Home Water Clinic is for general informational and educational purposes only. It is not professional plumbing, electrical, gas, or engineering advice, and it is not a substitute for an inspection by a qualified, licensed professional who can see your equipment and your home.
Water heaters, water softeners, and filtration systems vary by brand, model, age, and installation. Always follow your manufacturer’s manual and the labels on your equipment. Where our guides and your manual disagree, follow the manual.
Safety first
- Gas work: Gas lines, gas valves, burners, and venting must be serviced by a licensed plumber or gas technician. If you smell gas, leave the building and call your gas utility or 911 from outside.
- Electrical work: Electric water heaters run on 240 volts. Turn the breaker off and verify power is off before opening any panel. Wiring and breaker work should be done by a licensed electrician.
- Hot water and pressure: Water heaters store scalding water under pressure. Never cap, plug, or disable a temperature and pressure (T&P) relief valve.
- Codes and permits: Many installations and replacements require a permit and must meet local code. Check with your local building department.
