FAQs
Why is on-site water analysis important for Winchester homes and businesses?
Winchester sits above a chalk aquifer that produces naturally hard water rich in calcium, magnesium and occasional traces of iron and nitrates. On-site testing lets us measure the exact mineral, metal and microbial levels coming out of your tap so we can design a treatment system that targets local conditions rather than using a one-size-fits-all national estimate.
What contaminants or parameters do you test for during a visit?
Our field technicians carry calibrated electronic meters and test kits to measure hardness, TDS (total dissolved solids), pH, alkalinity, iron, manganese, nitrate, chlorine, lead, copper and bacterial activity (presence/absence). If your supply is from a private well, we can also screen for pesticides, sulphates and coliforms. Results are recorded and explained on site so you know exactly what is in your water.
How long does the on-site analysis take and when will I see the results?
A standard residential analysis in Winchester usually takes 45–60 minutes. Commercial premises with multiple draw-off points can take 1–2 hours. Most field tests deliver instant digital readings, so you’ll see preliminary results before we leave. If you opt for extended lab testing (e.g., detailed microbiological profile), samples are couriered the same day and a full report is emailed within 5 working days.
What purification solutions do you offer based on the test results?
After testing, we recommend only the equipment needed to solve the specific issues we find: water softeners for hardness, whole-house sediment or carbon filters for taste/odour and chlorine, reverse osmosis units for nitrate or heavy-metal reduction, and UV disinfection for bacterial concerns. All systems are sized to match your flow rate and usage patterns, ensuring efficiency and compliance with WRAS guidelines.
Will installing a purification system increase my water pressure or maintenance burden?
Properly sized modern systems cause minimal pressure drop (typically <1 bar). We use high-capacity bypass valves and resin tanks to keep flow strong. Maintenance is straightforward: softeners require salt refills every 4–6 weeks, RO systems need annual cartridge changes, and UV lamps are replaced yearly. We offer service plans that include reminders, parts and labour so you don’t have to worry about upkeep.
How much does on-site testing and a complete treatment system cost in Winchester?
A basic residential on-site analysis is £85, which is waived when you proceed with a system installation. Full-home softening systems start around £950 installed, whole-house carbon filtration from £550, and point-of-use RO drinking stations from £345. Because every property’s water profile is unique, we provide a written quotation after testing that itemises equipment, installation, warranties and optional service contracts, with no hidden fees.
