The Plumbing–Purification Connection
Water quality and plumbing integrity are inseparable. Contaminants not only pose health hazards but can also ruin valves, gaskets, and pipework. HEP’s comprehensive approach puts purified water at the heart of the plumbing system rather than treating it as an afterthought.
Site Assessment and Water Profiling
HEP engineers begin with a detailed survey that includes:
- Testing mains water for hardness, pH, turbidity, microbial count, and chemical residues
- Inspecting pipe materials—copper, galvanised steel, PEX, or PVC—for potential leaching risks
- Mapping flow rates to ensure purification equipment matches peak demand
- Identifying points where cross-connection or backflow protection may be required
Integration Without Compromise
Once the water profile is known, HEP designs a purification setup that:
- Fits within existing service cupboards or utility rooms
- Maintains adequate pressure for showers, irrigation systems, and commercial processes
- Allows for bypass circuits to facilitate maintenance without disrupting supply
- Complies with Water Supply (Water Fittings) Regulations and local building codes
Commissioning and Verification
After installation, technicians flush the system, sanitise all lines, and carry out post-treatment tests to confirm:
- Microbial counts fall within drinking water standards
- Residual chlorine levels are balanced to prevent bacterial regrowth
- Hardness values align with manufacturer recommendations for boilers and water heaters
- Flow and pressure remain stable across all outlets
Core Purification Technologies Used by HEP in Lancing
Sediment Filtration
A first defence against rust, sand, and silt. Spin-down or cartridge filters trap particles down to 5 microns, protecting downstream membranes and resins from premature fouling.
Activated Carbon Adsorption
Granular activated carbon (GAC) and carbon block filters excel at removing chlorine, chloramine, pesticides, and unpleasant flavours. High-iodine-number GAC ensures maximum adsorption capacity while maintaining good flow.
Ion Exchange Water Softening
Hardness—principally calcium and magnesium—creates limescale that clogs heating elements and piping. HEP installs metered softeners that regenerate based on actual usage, conserving salt and water.
Reverse Osmosis (RO)
For properties requiring high-purity water, RO membranes remove up to 99% of dissolved solids. Systems are sized to produce sufficient daily volume for drinking, cooking, and specialised equipment such as espresso machines or fish tanks.
Ultraviolet (UV) Disinfection
UV lamps neutralise bacteria, viruses, and protozoa without adding chemicals. An integrated sensor monitors lamp intensity, triggering alerts if dosage falls below safe thresholds.
pH and Mineral Balancing
After aggressive purification—such as RO—the water can become slightly acidic. Calcite or magnesium oxide filters re-mineralise and stabilise pH to protect copper pipes and enhance taste.

Regulatory Framework Guiding Water Purification in Lancing
Water Supply (Water Quality) Regulations
Mandate that potable water meets strict microbiological and chemical criteria. HEP designs systems to keep every metric comfortably within statutory limits.
Building Regulations Part G
Covers sanitation, hot water safety, and water efficiency. Integrated purification must align with flow rate and temperature safety requirements.
WRAS Approval
All fittings, valves, and pipes used by HEP carry the Water Regulations Advisory Scheme mark, ensuring compatibility with UK drinking water.
Environmental Health Inspections
Commercial premises undergo regular checks. HEP supplies test certificates and maintenance records that demonstrate due diligence, streamlining the inspection process.
Best Practices for Residents to Maximise Purification Performance
Simple Daily Habits
- Run cold water taps for 30 seconds after extended non-use, such as holidays
- Keep aerators clean by soaking them monthly in vinegar to dissolve mineral deposits
- Avoid chemical drain cleaners that could backflow into purification units
Seasonal Considerations
Spring and autumn are ideal for comprehensive system reviews, as temperature and usage patterns shift. Residents can:
- Check softener salt levels at the start of each season
- Inspect UV lamp indicator lights to confirm operational status
- Note any taste difference following municipal supply maintenance and report anomalies
The Science Behind Common Contaminants in Lancing
Iron and Manganese
These metals originate from both natural geology and corroded pipe interiors. They can cause staining and metallic flavour. HEP employs oxidation-filtration stages, often aeration or catalytic media, followed by fine filtration to remove precipitated particles.
Nitrates
Agricultural activity around the South Downs can elevate nitrate levels in certain boreholes. Ion exchange resins or RO membranes are required to keep concentrations below 50 mg/L nitrate (NO₃).
Microplastics
Emerging research detects microplastic particles in surface water supplies. Ultrafiltration membranes with pore sizes below 0.1 microns physically block these particles, supplementing conventional treatment.
PFAS (Per- and Polyfluoroalkyl Substances)
Known as “forever chemicals,” PFAS demand high-performance activated carbon or advanced ion exchange media. HEP actively monitors regulatory developments and upgrades systems when new limits are introduced.
Plumbing Considerations Specific to Purified Water
Galvanic Corrosion
Purified, low-TDS water can be more aggressive towards metal pipes, driving galvanic action between dissimilar metals. HEP mitigates this with:
- Dielectric unions
- pH correction filters
- Use of plastic or stainless-steel fittings in critical zones
Flow Limitation
Multiple filtration stages increase resistance. HEP optimises line sizing or installs booster pumps where necessary to preserve pressure at distal points like attic bathrooms.
Backflow Prevention
Regulations require check valves or air gaps to protect the public supply. Purification systems can create negative pressure zones that must be isolated. HEP incorporates RPZ (Reduced Pressure Zone) valves where mandated.
Indicators That a Lancing Property May Need Purification Upgrades
Unpleasant tastes, scaling kettles, discoloured laundry, or low appliance efficiency often point to water quality issues. Additional warning signs include:
- Recurrent pinhole leaks in copper pipes
- Premature failure of seals in mixers and valves
- Cloudy ice cubes or white film on glassware
- Elevated energy bills due to limescale-coated heating elements
Addressing these symptoms early with a properly engineered purification solution prevents larger repair costs and health concerns down the line.
Smart Technology for Real-Time Water Quality Monitoring
Connected Sensors
Modern systems incorporate inline probes for:
- Conductivity and TDS tracking
- Chlorine residual measurement
- Temperature surveillance to prevent Legionella growth
Data streams to mobile apps or building management systems, enabling users to spot deviations instantly.
Predictive Maintenance Algorithms
Machine learning analyses historical flow and contaminant data to predict media exhaustion. HEP deploys these algorithms to schedule proactive service visits, avoiding sudden filter breakthrough or pressure loss.
Leak Detection Integration
Purification units can interface with acoustic or moisture sensors positioned near vulnerable plumbing joints. Early alerts facilitate swift isolation, minimising water damage and downtime.
Sustainable Practices Embedded in HEP’s Purification Projects
- Selection of recyclable filter housings and cartridges
- Use of energy-efficient pumps with variable-speed drives

By synchronising these projects, property owners reduce disruption and achieve cohesive, long-lasting plumbing health.
Common Myths About Residential Water Purification Debunked
-
“Lancing’s tap water is already safe, so purification is redundant.”
Safety standards define maximum allowable contaminant levels, not necessarily optimal taste or long-term appliance protection. Purification enhances both aspects. -
“Water softeners make water salty.”
Sodium levels added by ion exchange softeners are typically very low. For individuals on restricted-sodium diets, separate drinking taps fed by RO units can easily resolve concerns. -
“Filtering water removes essential minerals.”
RO and de-ionisation strip minerals, but remineralisation cartridges restore balanced pH and electrolytes, delivering a refreshing, neutral flavour. -
“Purification systems require constant attention.”
With modern smart monitoring and periodic professional servicing, day-to-day user interaction is minimal—usually limited to topping up salt or replacing quick-change cartridges.
