<p>A flexible hose (10) having an inner tube member (14) made from a thermoplastic elastomer material and an outer tube member (12) made from a non-elastic polyester material. The inner tube member (14) is secured to the outer tube member (12) only at an inlet coupler (18) and an outlet coupler (16). The inlet coupler (18) is constructed to secure to a water supply provided from a conventional household water spigot. The outlet coupler (16) incorporates a flow restrictor (21) allowing the inner tube member to equalize in pressure with pressurized water received from the water supply. Pressurized water expands the elongated inner tube member longitudinally along a length of the inner tube member and laterally across a width of the inner tube member thereby substantially increasing the length of the hose to an expanded condition wherein the hose contracts to a substantially decreased length when there is a decrease in pressurized water.</p> |
