Water hose is a vital part of your boat. It's used in lieu of pipe because it's flexible and it provides better and easier installations, especially where tight spaces, movement and vibration are a factor (typical in most boats). As plumbing they deliver, circulate and discharge the fluids (liquid and gaseous) for most operating systems (engine, generator, exhaust, bilge, drainage, live well, sanitation, potable and grey water, ventilation, gas appliance, climate control, etc.) and they're often connected as an extension of a hole in your boat (above and below the water line)
