- High leakage rates – up to 15 % loss of water volume per year, inflating utility bills.
- Frequent replacements – low‑grade caps fail after 3‑6 months, causing downtime.
- Regulatory non‑compliance – missing CE/ISO certifications can halt shipments to the EU and NA markets.
- Excessive procurement cost – generic imports often cost 30‑40 % more than a custom‑cast solution.
- Long lead times – overseas suppliers average 45 days, while production lines need parts within 7‑10 days.
