New kitchen faucet, a bathroom upgrade, or replacing a fixture that’s finally given out — faucet installation looks simple until an old San Francisco supply setup gets in the way. Send a few details and you’ll get a straight answer from one vetted, licensed San Francisco plumber — not five companies fighting over your phone number.
Tell us the fixture and where it’s going, and you’ll get a clear read on what the swap actually involves in your home.
Swapping a faucet is a quick job in a newer home and a different story in an older San Francisco one. The complication usually isn’t the faucet — it’s what’s under the sink. In pre-war flats and Victorians the angle stops and supply lines are often original, corroded, and seized, so the honest first step is checking whether the shutoffs even turn before the old fixture comes off. Getting a clean install often means replacing those valves and lines at the same time so you’re not left with a faucet that works and a shutoff that won’t.
Matching the fixture to the sink
The other thing worth getting right before you buy is fitment. Sinks and countertops are drilled for a set number of holes — single-hole, three-hole widespread, or a specific spread — and a faucet that doesn’t match leaves you with an exposed hole or a fixture that won’t sit right. Vintage and imported fixtures common in San Francisco homes sometimes use non-standard connections too. A plumber can tell you what fits your setup, install it sealed and leak-free, and handle the drain and any deck plate so it looks and works the way it should.

San Francisco faucet installation questions
Why does a simple faucet swap turn into more in an old home?
Because the shutoff valves and supply lines under the sink are often original and corroded. If an angle stop won’t close or a supply line is seized, it has to be replaced to install the new faucet safely — a plumber checks that first so the job doesn’t stall halfway.
How do I know the faucet I bought will fit?
It comes down to how many holes your sink or counter is drilled for and their spacing. A single-hole faucet won’t cover a three-hole setup without a deck plate, and a widespread needs the right spread. Tell a plumber your setup and they’ll confirm the match before installation.
Can you install a faucet I already bought?
Yes — a plumber can install a fixture you supply, including vintage or imported models, as long as it fits the sink. They’ll flag any adapter or extra part needed for a non-standard connection so it installs sealed and leak-free.
