Reverse Osmosis System: Frequently Asked Questions
What is included in your free Water Health Index test?
Every Zenith water test gives you your full Water Health Index report, built from 11+ parameters that combine professional water chemistry with your water’s performance in your home. A certified technician comes to your home and uses a professional-grade digital photometer to test your water for multiple chemistry parameters in under 2 minutes using a small water sample: alkalinity, hardness, pH, phosphate, ammonia, nitrite, and nitrate. Results are precise and digital, not a color comparison or a test strip held up to the light. We then combine the chemistry readings with other parameters to calculate your proprietary 0-100 Water Health Index score, and you receive a clear written report before we leave.
For specialist concerns, bacteria, well water contaminants, or specific chemical testing beyond our standard test, paid certified lab testing is available, covering 150+ contaminants. Cost varies depending on what needs to be tested. Ask your Zenith technician at the water test visit.
How does a reverse osmosis system work?
A reverse osmosis system uses a multi-stage filtration process to reduce up to 99% of contaminants from your drinking water. Water first passes through a sediment pre-filter to catch particles, then a carbon filter to reduce chlorine and chloramines. The water is then pushed under pressure through a semipermeable RO membrane with pores as small as 0.0001 microns. That’s small enough to block most dissolved solids, including lead, PFAS, fluoride, and arsenic. A final post-filter polishes the water for taste before it reaches your dedicated faucet.
What does a reverse osmosis system remove from drinking water?
Our RO systems can reduce up to 99% of:
Heavy metals: lead, mercury, arsenic, chromium 6. PFAS, or ” forever chemicals. Fluoride, nitrates, sulfates. Chlorine, chloramines, and disinfection byproducts (TTHMs, HAA5). Pesticides, VOCs, and pharmaceutical residues. Calcium and magnesium contribute to water hardness. Most bacteria, viruses, and protozoa, especially when paired with our UV stage.
Actual reduction depends on water conditions, system maintenance, and contaminant type.
Is reverse osmosis water safe and healthy to drink?
Yes. Reverse osmosis water is generally considered among the safest, purest drinking water you can produce at home. RO removes most harmful contaminants while leaving water that’s crisp and clean-tasting. Some homeowners ask about minerals. Our systems include an alkaline and mineral post-filter that reintroduces beneficial minerals like calcium and magnesium into your water. You get the best of both worlds: cleaner water with healthy mineral content.
Do I need a water softener if I have a reverse osmosis system?
For many homes, yes. Here’s why. Most municipal water supplies run roughly 10 to 25 grains per gallon hard. A water softener uses ion exchange to reduce calcium and magnesium from your whole home: showers, laundry, appliances, and plumbing. An RO system polishes only your drinking water. Install a water softener with an RO, and you get soft water at most taps, plus cleaner drinking water at your kitchen sink. Our Performance and Elite bundles include both.
How often do reverse osmosis filters need to be replaced?
Typical replacement schedule:
Pre-filters (sediment plus carbon): every 6 to 12 months. Post-filter (carbon polishing) every 12 months or so. RO membrane: every 2 to 3 years, depending on your water quality and usage.
Our annual maintenance plan covers filter changes, sanitisation, and a system health check. You don’t have to track schedules yourself.
