American Standard Filter Faucet Cartridge - AMS-A954410

A954410-0070A is American Standard's filter faucet cartridge, the ceramic disc valve cartridge that goes inside the faucet body and controls flow. Seals are included with it, so you are not sourcing O-rings separately.

A constant drip with the handle shut is almost always the valve cartridge, not the spout or aerator. This American Standard ceramic disc cartridge replaces that valve and ships with its seals, which is the other common leak point. If the leak is instead coming from around the base of the handle or the spout collar, that is a body or spout seal and a cartridge swap will not stop it.

Seals come with it. The A954410 cartridge kit includes the seals, so one part number covers the rebuild of the valve.

For high-traffic washrooms, ceramic disc is the type you want. Ceramic discs seal disc-against-disc rather than crushing a rubber washer against a seat, so they do not wear the way a compression stem does and they hold a drip-free shutoff far longer. This American Standard cartridge is a ceramic disc valve. If your faucet is an older compression two-handle unit, it takes stems and washers instead and this cartridge is not the part for it.

This is routine in-house maintenance work. Shut the stops under the fixture, pull the handle and retaining nut, lift the old cartridge out, and drop the new one in with the supplied seals. American Standard lists it as easy to install and no soldering or pipe work is involved. Keep the orientation of the old cartridge in mind as you pull it, since the inlet ports have to line up with the body.

If your units are fitted with the American Standard faucets that take A954410-0070A, yes, this is the sort of part worth holding on the shelf. Dripping faucets are the single most common plumbing call in an apartment portfolio, the repair is a cartridge and seals, and having the part in hand turns a two-visit job into one. Confirm the cartridge matches the faucet model in your units before standardizing on it, since American Standard uses several cartridge styles across its lines.

Because it is an internal part. The cartridge sits inside the faucet body where nothing is visible, so there is no decorative plating to match to chrome, brushed nickel, or bronze trim. One part number covers the faucet regardless of what finish the trim is.
