Water Heater Parts & Accessories

Keep your hot water reliable with quality water heater parts and accessories. This collection covers components for tank, tankless, electric, gas, and heat pump units, helping you restore performance, extend lifespan, boost efficiency, and reduce energy costs.

Find replacement heating elements and thermostats for electric models, anode rods and dip tubes to fight corrosion and deliver steady flow, and temperature and pressure relief (T&P) valves for safe operation. For gas units, shop gas control valves, thermocouples, igniters, and pilot assemblies. Support components include venting kits, condensate neutralizers, expansion tanks, recirculation pumps, mixing valves, dielectric unions, nipples, drain pans, insulation blankets, leak detectors, drip alarms, flush kits, and descaling hoses.

Choosing the right part is straightforward: match the heater’s model number, capacity, and fuel type. For electric systems, confirm voltage, wattage, and thread base on elements. For gas, verify control valve style and thermocouple or igniter length. Select anode rods based on water chemistry (magnesium, aluminum, or powered). Pick T&P valves with the correct pressure and temperature ratings, and confirm NPT sizes on all fittings. Look for OEM or proven universal options, NSF-listed materials, and proper clearances for venting and condensate routing.

Installation is manageable with basic plumbing tools. Shut off power or gas, close the cold supply, and drain as needed. Use PTFE tape or thread sealant on connections, tighten to spec, and test for leaks. Purge air, restore power or relight, set temperature to 120°F, and verify code compliance. Add dielectric isolation to curb galvanic corrosion, and insulate hot-water lines to hold heat.

Plan maintenance: flush annually, inspect anodes every two to three years, test the T&P valve yearly, check expansion tanks, and replace worn gaskets. Upgrading smart recirculation or leak alarms can cut wait times, save water, and protect your home. Shop trusted brands for reliable, code-compliant results.
