The Eva 6410 is often confused with the Eva 6400 single handle (a 1255 faucet). The 6410 and the Boardwalk 84820 are two handle faucets with the 1224 or 1234 depending on vintage, and the only reliable tell is the stem material.
Before you start. Shut off the two small valves under the sink by turning them clockwise, then open the faucet to confirm the water has stopped. Plug the drain so small parts cannot fall in. You will need a screwdriver, an adjustable wrench or pliers, and for most handles a hex key (an Allen wrench, sold as an inexpensive set at any hardware store). If a shutoff valve will not turn or starts to drip, or anything is corroded and will not loosen with moderate force, stop and see when to call a plumber. New to this? Start here explains the parts and tools in plain language.
