FAQs
What benefits does a reverse-osmosis (RO) system bring to homes and businesses in Manchester?
Reverse-osmosis removes up to 99% of dissolved salts, chlorine, heavy metals, pesticides, micro-plastics and other contaminants that are often present in Greater Manchester’s mains supply. The result is fresher-tasting water, clearer tea and coffee, better protection for kettles and steam appliances, and reduced reliance on bottled water, which cuts both costs and plastic waste.
How is an RO system installed alongside my existing plumbing?
Our certified plumbers mount the compact RO unit (usually under the kitchen sink), connect it to the cold-water feed with a dedicated isolation valve, install a pre-filter, route purified water to a separate drinking tap (or your fridge/ice-maker), and fit a small drain saddle for the concentrate line. Most domestic installations take 2–3 hours and do not require major pipework changes or floor lifting.
What ongoing maintenance is required, and how often?
An RO system has three main service points: pre-filters, the RO membrane, and the post-carbon filter. In Manchester’s moderately hard water, we recommend replacing pre-filters every 6–12 months, the membrane every 24–36 months, and the post-filter annually. Our service visit includes sanitising the housing, checking flow restrictors and pressure, and testing TDS (total dissolved solids) to ensure the system is performing to specification.
How much does a complete installation cost?
For a typical three-stage domestic RO system supplied and installed in the Manchester area, prices start at £395 including VAT. Larger units, remineralisation stages, or connections to fridges and coffee machines add £50–£150. Annual maintenance packages start at £85. Commercial high-capacity systems are quoted case-by-case after a free site survey.
Will an RO unit waste a lot of water?
Modern 1:1 or 2:1 efficiency membranes produce one litre of purified water for every one to two litres sent to drain. To lower waste even further, we can fit a permeate-pump kit or connect the concentrate line to a garden water butt for non-potable reuse. Considering the low daily drinking/cooking volume (typically 5–10 L per household), your overall water bill increase is usually under £1 per month.
Do you cover the entire Greater Manchester region for emergency call-outs and warranty repairs?
Yes. Our fleet of WRAS-approved plumbers operates across all ten boroughs—Manchester, Salford, Trafford, Stockport, Tameside, Oldham, Rochdale, Bury, Bolton and Wigan—24/7 for urgent leaks or pressure issues. Standard warranty repairs (parts and labour) are completed within two working days, and most consumables are carried on the van so your system is rarely out of service for more than an hour.
