The service life of PVC hoses typically ranges from 1 to 10 years-significantly shorter than that of rigid PVC pipes-with the actual duration heavily dependent on material grade and operating conditions.
Standard consumer-grade hoses: Items such as garden hoses or shower hoses generally last 1–5 years under conditions of frequent use or prolonged sun exposure; some low-quality products may even become brittle, crack, or leak in less than a year.
High-quality modified hoses: Products formulated with UV-resistant additives and reinforced construction can last close to 10 years when used properly in mild indoor environments.
Key influencing factors: Direct UV exposure, prolonged contact with high-temperature fluids, high-pressure operation, and frequent bending or movement all accelerate hose aging and shorten its service life.
Prompt replacement is necessary when signs of yellowing, hardening, cracking, or leakage at the connections appear, in order to prevent sudden ruptures or leaks.
