What it means
Fixture shutoff valves, often called angle stops, sit on the supply line between the branch and the fixture connector. Quarter-turn or multi-turn designs allow quick isolation during leaks, faucet swaps, or toilet repairs.
Old compression valves on galvanized or copper stub-outs may leak when exercised after years idle. Replacing stops during fixture upgrades prevents emergency shutoff problems.
Why it matters in Santa Cruz County
Older Santa Cruz cottages often have corroded stops tucked into tight vanity cabinets near the coast. Multi-unit buildings in downtown Santa Cruz benefit from labeled stops so tenants can contain a leak before the main is located.
Homeowner tip
Gently turn each stop off and on once a year; replace any that drip or will not fully close.
