The short answer

Inventory the actual faucets first. Confirm fitting compatibility and the intended use of each fixture.

Avoid the one-size order

Ask the supplier or installer to match the existing faucet model and threads. Separate private bathroom sinks from kitchen or common-area fixtures. Keep one verified specification per fixture group so later replacements do not depend on guesswork.

EPA’s WaterSense faucet criteria cover specified faucet types, not every kitchen or public-lavatory faucet. [1]

Try a correctly matched replacement through your normal authorized maintenance process before buying a portfolio-wide quantity. Record the installed part number and any performance issue. Efficiency labeling does not resolve compatibility or local plumbing requirements.
