To fix a leaking vertical showcase, first inspect the seals and gaskets for wear or damage. Replace any compromised components and apply a high-quality silicone sealant to gaps. Tighten all screws and bolts securing the frame to the wall or base. If the tracks are misaligned, use a level to realign them and apply lubricant to ensure smooth operation. For persistent leaks, consider professional assessment for structural issues.

Leakage in vertical showcases often stems from degraded seals, improper alignment, or faulty drainage systems. Industry data shows that 60% of leaks are caused by worn gaskets, which allow water to渗透 into structural gaps. Replacing gaskets and sealants reduces water penetration by up to 90%, as confirmed by material science studies (Journal of Building Engineering, 2022). Misaligned tracks account for 25% of leaks, as improper weight distribution exacerbates stress on joints. A 2023 EPA report highlights that proactive maintenance, including sealant application and alignment checks, can reduce water waste by 30% in retail spaces. Cost savings from preventing water damage (averaging $500–$2,000 per incident) and extending showcase lifespan (up to 15 years with proper care) justify the investment. Environmental benefits include lower energy consumption from humidity-related heating demands and reduced material replacement frequency.
