These are notes from Jan 2023 me to future me – here’s what you need to know:
- To fix the 2007 Pegasus [is that a Home Depot brand?] widespread two-handled faucet on the upstairs bathroom sink
- About fixing leaking sink faucets more generally
Diagnosis. Figure out if the hot or cold is leaking by turning off the water supply lines one at a time.
The part to change to stop the dripping is the cartridge (in a one-handled faucet) or, in this widespread two-handle bathroom sink, the faucet stem. It comes with a new retaining clip. Cartridge vs. faucet stem is mostly a matter of terminology.
