Re: Google search on "Reinforced Hose" gone awry
My cockpit drains use that the same reinforced hosed used for wet exhausts. It's as old as the hills but it must be good stuff because whoever installed it many moons ago not only used a single hose clamp to attach it to the through hull but also missed the through hull nipple entirely and merely clamped the hose just above. Amazingly, the hose held fine in this condition. The cockpit drains connect to through hulls located inside the engine compartment so I'm guessing the theory of using wet exhaust hose is that it is better able to handle the elevated temps that occur there.
My galley sinks, on the other hand, use a thick nylon reinforced pvc hose that is see through, although you'd almost need to be a contortionist to use it to check for blockages and waterline!
