Commonly used flexible stainless steel braided hoses must be used in accessible areas but many braided steel hoses are used in accessible but closed areas where fumes from stored chemicals can react with the woven mesh, causing rust spots that lead to hose failures.
Flexible stainless steel braided hoses with sharp bends when fitted are also more prone to failure.
Failures are not uncommon.
Flexible stainless steel braided hoses must be WaterMarked but there are numerous non certified braided hoses sold. A plumber fitting a flexible braided steel hose does not guarantee compliance but compliance is not a guarantee of immunity from attack by chemical fumes or longevity.
