WET SPOT is the original portable water softening system. WET SPOT works basically the same way as a residential or commercial water softener, only it’s been designed to be portable and is recharged manually, requiring no electrical hook up! Backed by a 12 Year Warranty, WET SPOT products are designed to last and constructed out of strong, low maintenance materials that can withstand even harsh marine environments. PVC, aluminum, brass hose fittings, rubber wheels, even our labels are manufactured of a specialized material to last and look great for years to come… This WET SPOT model is recommended for boats 100′ and up. (Depending on how hard water is, and usage). This WET SPOT is for extra-large and/or built-in applications only. Before you buy a WET SPOT SUPER model, please realize that it is difficult for most people to single handedly move on and off a docked vessel. Many clients have opted for two WET SPOT PLUS Models, instead of one WET SPOT SUPER model. Length 45″ Width 7.25″ Height 10.5″ Weight 50lbs.
