To fix a leaking water fountain, first shut off the water supply and drain the basin. Inspect the fountain for visible cracks, loose bolts, or damaged components. Replace worn seals, gaskets, or O-rings, especially around the pump and pipes. Tighten loose connections and apply waterproof sealant to gaps. For severe leaks, consider professional repair or replacement.

Leakage in water fountains often stems from worn mechanical parts or structural damage. According to a 2022 study by the American Water Works Association, 60% of leaks in public water systems are caused by faulty seals and joints. Neglecting these issues can lead to significant water waste; the Environmental Protection Agency (EPA) estimates that a single dripping faucet wastes 3,000 gallons annually. Proactive maintenance reduces repair costs by up to 40%, as noted in a 2021 report by the National Association of Water Quality. Cracks in concrete basins, common in older fountains, require epoxy injection or replacement to prevent further damage. Additionally, pressure imbalances in pipes can force leaks, which are addressable by adjusting valves or installing pressure-reducing devices. Regular inspections every six months minimize long-term expenses and environmental impact.
