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 has 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 the labels are manufactured of a specialized material to last and look great for years to come.
