The patent-pending H2O Simplified 3-in-1 water treatment system in a luxury coach service bay
For Prevost Conversions

Bay-Installed Water Treatment for
Your Prevost

A converted Prevost is a coach full of systems, and most of them live in the bays. This is one more that belongs there: softening, filtration and a deionized final rinse from a single patent-pending unit, sized to the space you have.

The One Variable Left

Everything about this coach was specified. The water wasn't.

A Prevost starts life as a shell and ends up as whatever the conversion house and the first owner decided it should be. Paint laid by hand. Stainless polished. An interior that took months. Then it rolls up to a resort post somewhere new and drinks whatever happens to be in the ground there. Hard water does not know what it just connected to. It leaves film on polished trim and dries to white spots on a finish that shows every single one. Behind the bay doors it builds scale in the water heater and lines. Every other choice on this coach was made by somebody. The water is the leftover.

The post is the post

You control how the coach is washed and where it is stored. You choose who touches it. You do not control what comes out of the pedestal at the next stop. Untreated, that water carries the minerals that build scale everywhere behind your bays, starting with the water heater.

Where a coach like this gets judged

White spots on hand-laid paint. Film on polished metal. Glass that slowly stops looking clear. Those show up first on the surfaces people walk right up to, which on a Prevost is essentially all of them.

The three stages

One unit in the bay, three things handled.

H2O Simplified is a patent-pending 3-in-1 water treatment system. It mounts in a service bay and travels with the coach, connecting to a suitable potable fresh-water source within the installation's operating limits. All three stages come out of the same package, configured to your bay and professionally installed. Nothing to roll out at the hookup and nothing to stow before you leave.

  • Softening: ion exchange ahead of the plumbing, which helps keep scale from building in the water heater, the lines and the fixtures. The shower ends up feeling the way the rest of the coach looks.
  • Filtration: clearer, better-tasting water at the galley and the master bath. Filter performance depends on the selected media and its condition.
  • The final rinse: deionized water for the last pass. Clean paint and brightwork can air-dry with less mineral residue, so nobody is walking the coach with a towel at seven in the morning.

Sizing and Installation

It gets sized to your bay, not to a catalog.

Coaches on the H3-45 and X3-45 shells, whichever house converted them, share a bay-based service layout, and that is what this system is configured around. We work from the space you actually have, build to it, then quote it to your coach. Call it a fitment match and nothing further: Prevost and every conversion house own their own names and their own reputations.
