Discover how HEP’s Essential Minerals Plumbing transforms everyday tap water into a crystal-clear, revitalizing resource. Our advanced water purification systems retain the healthy calcium, magnesium, and trace elements your body craves while removing sediment, chlorine, and heavy metals that dull flavor and harm fixtures. Imagine turning on the faucet in Petros and tasting water that’s as bright and balanced as a mountain spring—clean enough for cooking, bathing, and brewing the perfect cup of coffee.
Behind that refreshing sip stands decades of engineering expertise. Every component—filter housings, mineral cartridges, smart flow valves—is selected for durability and easy maintenance, so you save time and reduce plastic waste from bottled alternatives. With HEP, you’re not just installing equipment; you’re investing in wellness, sustainability, and peace of mind for your home or business. Live better, drink better, and let the minerals do the talking.
FAQs
What are “essential minerals” in drinking water and why do I need them?
Essential minerals are naturally occurring nutrients—primarily calcium, magnesium, and trace elements like potassium and sodium—that your body needs for bone strength, nerve function, and overall metabolic health. Water is not the only source, but studies show mineralised water can contribute up to 20 % of daily requirements. Stripping all minerals can leave water tasting flat and may reduce its nutritional value, so our purification approach is designed to keep these beneficial minerals while removing harmful contaminants.
How does the Petros water-purification system remove contaminants but keep the good minerals?
Our system combines layered mechanical filtration, catalytic carbon adsorption, and a proprietary selective-membrane stage. Sediment and carbon filters first trap rust, sand, chlorine, pesticides, and volatile organic compounds. In the third stage, the selective membrane’s pore size and surface charge are calibrated to reject heavy metals, micro-plastics, and pathogens while allowing ionic forms of calcium and magnesium to pass through. The result is clean, safe water that still contains its natural mineral profile and has a crisp, balanced taste.
Will the system also soften hard water?
Yes, the system reduces hardness but does not completely de-mineralise the water. The catalytic carbon and membrane stages lower the concentration of scale-forming calcium and magnesium ions to below 60 mg/L, which is considered moderately soft, preventing limescale in pipes and appliances. At the same time, trace levels of these minerals remain so the water retains its desirable taste and nutritional benefits.
How often do I need to replace filters or service the unit?
For an average household of four, the sediment pre-filter should be replaced every 6 months, the catalytic carbon block every 12 months, and the selective membrane every 24 months. A built-in flow meter and LED indicator alert you when each stage reaches 85 % of its capacity. Annual professional check-ups are recommended to flush the system, sanitise housings, and verify water quality. Actual replacement intervals can vary with local water conditions and usage volume.
Is the system suitable for both municipal and well-water sources?
Absolutely. The layered filtration tackles chlorine, chloramine, and pipe-scale often found in municipal supplies, while the membrane’s 0.02 µm rating removes bacteria, cysts, and heavy metals common in well water. For very high levels of iron or sulfur, we may recommend a pre-treatment stage—our technicians can test your source water and design the right configuration.
What certifications and safety standards does the Petros system meet?
All wet components are NSF/ANSI 42 and 53 certified for material safety and contaminant reduction claims. The selective membrane carries NSF/ANSI 401 certification for emerging contaminants such as pharmaceuticals. Systems are pressure-tested to ASME standards and are compliant with South African National Standard (SANS 241) drinking-water requirements. Each unit ships with a batch-specific laboratory report confirming that purified water meets or exceeds WHO guidelines.
