The answer to 'how to maintain faucet installation' is to regularly inspect, clean, and replace components as needed. This includes checking for leaks, cleaning aerators, and replacing washers or cartridges when they become worn. Proper maintenance can extend the lifespan of your faucet and prevent costly water damage.
Maintenance should be performed every 6-12 months, or anytime you notice issues like reduced water flow, dripping, or leaks. If you're not comfortable performing the maintenance yourself, it's best to call a professional plumber to ensure the job is done correctly.
