How long is fire hose good for?
Taking care of a fire hose the “prescribed” way can lead to a useful life of 10–20 years. More vigorous use will cut down on the lifespan of course, but good fire hose care can still go a long way in keeping your hoses working at maximum efficiency for a longer length of time.

(i) Percolating / Unlined / Canvas hose which are made of vegetable fibers. (ii) Non percolating hose made up of plastic material forming both lining as well as the outer cover.
Why are fire hoses different colors?
Though a bit more expensive than coating, colored yarn is also used to create tracer stripes in some models of hose, so that different colored stripes can indicate the different hose diameters or be used to color code the hose in a system of the end user’s preference.
What is a percolating hose?
Fire hose for extreme fires Sabre™ is a percolating hose which means that water seeps through the fabric jacket. This is achieved by pin pricking the hose so that water can flow through the fabric jacket and offer protection against burning coals. A thin water barrier thus prevents the hose from getting burnt.
