Our products maintain the same warranty under all water conditions, but you may want to consider a whole house water treatment system if the water quality is a concern. This is desirable for drinking as well as protecting the plumbing systems, decorative hardware, faucets, and glass from the negative effects of hard water. The EliteSteam steam generator can operate in conjunction with a water softener. EliteSteam recommends, but does not require, that a generator pan and auto drain be installed; both are offered as accessory options.
