- High price volatility: Imported caps often fluctuate 15‑25 % due to tariffs.
- Low durability: Sub‑standard alloys corrode within 12 months, causing water back‑flow.
- Long lead times: Typical 6‑8 week delivery stalls construction schedules.
- Regulatory risk: Missing CE, FCC, or ASTM certifications can halt projects.
Fact: A 2025 industry survey of 312 US contractors revealed that 38 % cite “cap failure” as the top cause of drainage re‑work.
