Water heater accessories help you install, upgrade, and maintain reliable hot water in homes and commercial spaces. From safety parts to efficiency boosters, the right add-ons reduce energy use, prevent leaks, and extend the life of your tank or tankless unit.

Popular water heater accessories include anode rods to fight corrosion, expansion tanks to protect plumbing from thermal expansion, drain pans with alarms to catch and alert on leaks, and temperature and pressure relief valves for critical safety. Improve performance with recirculation pumps for faster hot water at the tap, insulation blankets and pipe wraps to cut standby heat loss, and thermostats or mixing valves for steady, safe outlet temperatures. For gas models, look for thermocouples, igniters, drip legs, and venting kits; for electric units, consider heating elements, thermostats, and high‑quality dielectric unions and flex connectors. Tankless systems benefit from scale reduction filters, service valve kits, condensate neutralizers, and proper combustion air and vent components.

Choosing the right water heater parts starts with compatibility: match thread sizes, voltage or gas type, BTU rating, and vent class to your model. Check local plumbing codes for requirements on expansion control, pan drainage, and discharge lines. Prioritize durable materials like stainless steel, brass, and magnesium, and select lead‑free, certified components where potable water contacts occur.

Installation tips: shut off power or gas, close the water supply, relieve pressure, and follow manufacturer instructions or hire a licensed plumber. Test for leaks, confirm T&P valve operation, and insulate exposed hot lines to save energy. Schedule routine maintenance with anode inspections, sediment flushing, and descaling to keep efficiency high.
