Homeowner Guide to Gate Valve Maintenance for Water Safety

Have you ever found yourself helpless when facing sudden plumbing emergencies? That moment when dripping water disrupts your peaceful night, and you wake up to discover a leaking pipe with no idea how to respond? The humble gate valve, often overlooked, actually holds the key to your home's entire water system.

As a common control element in plumbing systems, gate valves serve as silent guardians of our water safety. Whether regulating daily water flow or stopping water during emergencies, these valves play an indispensable role. Yet many homeowners remain unfamiliar with proper gate valve operation, sometimes using incorrect methods that can shorten the valve's lifespan or lead to more serious leaks.

Different valves serve distinct purposes in plumbing systems:

Understanding gate valve construction enables better operation and maintenance:

1. Confirm no water pressure in system
2. Turn handle counterclockwise slowly
3. Stop when encountering resistance
4. If stuck, slightly loosen packing gland nut
5. Re-tighten nut after operation
6. Open top-floor faucet to release air

1. Turn handle clockwise gradually
