Imagine turning on your tap and watching crystal-clear water flow—free from sediments, heavy metals, chlorine taste, and microscopic contaminants. HEP’s reverse-osmosis systems bring laboratory-grade filtration to everyday living in Petros, driving water through multi-stage membranes that strip away up to 99 % of impurities while retaining the minerals you want for a refreshing, balanced taste. Easy-fit plumbing layouts, smart leak-prevention valves, and whisper-quiet pumps make installation seamless for both new builds and retrofits, so you can enjoy dependable water purification without remodeling your entire kitchen.
Beyond performance, every unit is engineered for efficiency and sustainability. Low-waste membrane technology reduces wastewater by up to 75 %, quick-change cartridges cut maintenance time to minutes, and optional remineralizers let you fine-tune pH to match local preferences. Backed by HEP’s responsive support team and a rock-solid warranty, these systems deliver pure peace of mind—drop by pristine drop.
FAQs
What is a reverse-osmosis (RO) water-purification system and how does it work?
A Petros RO system forces tap water through a series of pre-filters and then a semipermeable membrane that blocks up to 0.0001 micron particles. Dissolved salts, heavy metals, chemicals, and microorganisms are flushed to the drain, while only purified water reaches the storage tank and dedicated faucet. Most Petros units also include post-carbon polishing to improve taste before dispensing.
Which contaminants can a Petros RO system remove from my water?
Independent testing shows our RO systems typically reduce 95–99 % of total dissolved solids (TDS). This includes lead, arsenic, fluoride, nitrates, PFAS, chlorine, chloramine, pesticides, herbicides, pharmaceuticals, cysts (Giardia, Cryptosporidium), and many other organic and inorganic impurities. Specific removal rates vary by model and water quality; consult the performance data sheet for exact percentages.
What plumbing requirements are needed to install a Petros RO unit?
Installation usually takes 1–2 hours and requires: 1) a cold-water ½-inch (or ⅜-inch) feed under the sink; 2) enough space to mount the filter assembly and a 2–3 gal (8–11 L) storage tank; 3) a standard 1⅜-inch hole in the sink or countertop for the RO faucet; and 4) access to the household drain line for the reject (waste) water saddle. Petros provides all fittings, color-coded tubing, and a detailed guide. A qualified plumber or experienced DIYer can complete the job.
How often do filters and membranes need to be replaced?
For typical household usage (50–75 gal/week): • Sediment & carbon pre-filters: every 6–12 months • RO membrane: every 24–36 months • Post-carbon polishing filter: every 12 months. High-sediment or high-TDS water may shorten these intervals. Each Petros system has quick-change cartridges, date labels, and optional pressure-drop indicators to simplify maintenance.
How much water does the system produce per day and will the flow meet my needs?
Most residential Petros models are rated at 50–100 gal per day (GPD) under 60 psi feed pressure and 77 °F water temperature. The pressurized storage tank supplies 0.5–0.8 gal/min at the RO faucet—adequate for filling pots, coffee makers, and refrigerator ice makers. Larger GPD membranes and booster pumps are available for high-demand homes or commercial applications.
Does reverse osmosis waste water, and can I reduce it?
RO technology requires a concentrate stream to carry impurities to the drain. Petros systems operate at a 1:3–1:4 purified-to-waste ratio (1 gal pure for every 3–4 gal sent to drain). Efficiency can be improved by: • installing an optional permeate-pump kit (cuts waste up to 80 %), • maintaining proper feed pressure (60–80 psi), and • re-using reject water for landscape watering or household cleaning where local codes allow.
