The H2O Simplified 3-in-1 water system installed in a Newmar luxury coach service bay
For Newmar Coaches

Water Treatment for
Newmar Coaches

One patented system in the service bay softens the water, filters it, and gives you a rinse that dries without spots. We have built one into a Dutch Star. Your paint, your glass and your plumbing get the same water every time, no matter what the park is running.

The Catch

You bought a Newmar to keep. Hard water doesn't care.

Newmar owners keep their coaches. That is most of the reason people buy one, and it is why the wash matters more here than on a rig somebody plans to trade in three years. But every park, every rally lot and every friend's driveway hands you a different water, and most of it is hard. Minerals dry to spots on high-gloss paint. They sit on glass and brightwork until the glass stops looking clear. Out of sight, behind the bay doors, they build scale in the water heater and the pump. You specified this coach down to the cabinet pulls, and then you feed it whatever is coming out of the pedestal.

The finish shows everything

Hard water dries to chalky spots on a coach you just finished washing, and on glass and brightwork it keeps working until the haze stops buffing out. Repainting or re-polishing a coach at this level is not a small job. Not letting the spots land in the first place is the cheaper plan.

What happens behind the bay doors

Mineral-heavy water leaves scale inside the water heater, the pump and the fixtures, and it can carry the taste and smell of whatever sat in the campground line before you got there. None of that is visible until it becomes a service call, usually somewhere you did not plan to stop.

What Gets Installed

Soft water in, spots out, and a rinse you can walk away from.

H2O Simplified is a patented 3-in-1 unit that lives in the coach's service bay and goes where the coach goes. Softening, filtration and a true deionized rinse, in one package, fed by whatever hookup you happen to be parked at. We have built one into a Newmar Dutch Star, so this is not a theory about where it might fit.

  • Softening: ion exchange takes the calcium and magnesium out before the water reaches your plumbing, which helps protect the water heater, the pump and every fixture downstream of it. The showers feel different. That part you notice the first night.
  • Filtration: cleaner, clearer, better-tasting water at the galley and the bath, whatever the park's line was carrying.
  • True spot-free rinse: deionized water for the last pass, so you rinse the coach and walk away. No towels, no chamois, no ladder work chasing drips down the side.
  • Installed, not stowed: it is plumbed into the bay, not a tote you drag out and put back. Nothing to set up at the pedestal and nothing to leave behind at the last campground.

Tell us what you own

Bring your own water quality with you.

Call or send a note with your model and how you use the coach. We size the system to your bay, quote it, and install it. Pricing depends on the coach and the layout back there, so the first step is a short conversation rather than a shopping cart.
