The Water Heater Accessories & Fittings category covers the connection, protection and safety components that complete a water heater install. Beyond the tank or tankless unit itself, these details determine how reliably the system fills, heats, expands, drains and protects the surrounding structure—which directly affects service life, code compliance and callbacks.
Here you’ll find dielectric unions, flex connectors, shutoff valves, check and relief fittings, drain valves, drip pans, wall brackets, sediment traps, anode rods and thermal expansion accessories. These products support gas and electric storage tanks, tankless/on-demand heaters, hybrid heat-pump water heaters and booster or recirculation systems in both retrofit and new construction work.
When selecting water heater accessories and fittings, confirm pipe size and connection type (NPT, sweat, press, push-fit), water heater input and capacity, local code requirements, material compatibility (copper, PEX, CPVC, steel), temperature/pressure rating and whether a thermal expansion tank is required. The right accessory package improves safety, reduces corrosion and makes future service much faster.
Pro tip: Always plan the drain path first—size the drain pan, route the pan drain to an approved termination and install a full-port drain valve for annual flushing. A clean, service-friendly layout protects finished spaces and helps water heaters reach their full life expectancy.
