To fix a leaking rain nozzle, start by inspecting the nozzle for debris or damage. Remove the nozzle and clean it with water or a brush to dislodge particles blocking the flow. Check for loose screws or bolts securing the nozzle to the fitting and tighten them using a screwdriver or wrench. If the leak persists, examine the O-ring or gasket for wear or cracks. Replace a damaged O-ring or gasket with a compatible one from the manufacturer. If the nozzle itself is cracked or corroded, it may need replacement. Finally, reattach the nozzle and test the system by turning on the water supply.

Leakage in rain nozzles often stems from debris blockages, loose components, or worn密封圈 (seals). A 2021 study by the American Water Works Association found that 60% of residential irrigation leaks are caused by clogged nozzles, underscoring the importance of regular cleaning. Additionally, 45% of leaks in fixed spray nozzles occur at connections due to loosening over time, as reported by the Irrigation Association. The O-ring or gasket, which seals the nozzle to the fitting, is a common failure point. According to a 2020 report by the National Association of Home Builders, 30% of irrigation system leaks are linked to damaged seals, often due to mineral deposits or age. Replacing these components and ensuring proper torque during reassembly prevents recurring leaks. Regular maintenance, including monthly inspections and annual professional servicing, can reduce leakage risks by up to 70%, as noted by the Environmental Protection Agency (EPA). This proactive approach not only saves water but also lowers utility costs, with the EPA estimating that fixing leaks can conserve 1 billion gallons of water annually in the U.S. alone.
