Choosing the right flexible hose for kitchen and bathroom installations is key to ensuring safety, durability and trouble-free maintenance. This guide is designed for installers and specifiers working on residential and small commercial projects.
Why flexible hoses matter
Flexible hoses are a small component with a disproportionate impact on the long-term reliability of any plumbing installation. A poorly specified flexible can leak, fail under pressure cycling, or simply not last as long as the rest of the system. Spec it correctly and it becomes invisible. Spec it badly and it becomes the source of every callback.
Three things to check before specifying
- Inner braid material — Stainless steel braid is the standard for hot water lines (up to 90°C continuous, 110°C peak). PVC braid is acceptable for cold water but not recommended near heat sources.
- End connections — Match exactly to the threaded fittings on both sides (typically BSP 1/2" or 3/8" for kitchen taps and toilets). Universal connectors exist but compromise sealing reliability over time.
- Working pressure — Most domestic networks operate between 3-6 bar, but pressure-tested hoses up to 10 bar provide a safety margin against water-hammer events. Specify accordingly.
Common installation mistakes to avoid
The two most common installation errors are over-tightening (which deforms the gasket and creates a hidden leak path) and excessive bending (which kinks the inner core and reduces flow). Hand-tighten plus a quarter turn with a wrench is enough; the bend radius should never go below twice the hose diameter.
