NRv2 LoFlo Logo

(UK Patent No. 2440412)

LoFlo is a derivative of our patented NRv2 product, designed to manage and regulate the flow of water to a property by means of a “smart” non-return valve, therefore offering “whole site” protection against back-flow and contamination of water mains from internal sources.

Making this unique product by far the most efficient and cost effective method of reducing per capita consumption and finding “water and nutrient neutrality”.

The system is designed to reduce wastage from “normal” use of water services and to reduce water consumption by about 12% or 10 litres (2 gallons) per person per day of water used which could save the average property owner over £100 per property per annum in energy costs (source BBC) – assuming two-person occupation.

As with NRv2, the system can be used at any time during the life of a property, being installed without special tools without disruption to the household, unlike other flow restriction devices.

Perfect for use with all boiler systems including “Combi” boilers systems as LoFlo DOES NOT affect water pressures and minimum flow pressures offered by the UK water industry.

The system’s versatility means it is perfect for any property, even on Park homes and on caravan sites. (see images).
