Envirowater’s Free Flow Valve is unlike any other on the market.  What makes our product unique is its simplicity. Most water free systems require costly installation and ongoing maintenance. Our system is simple to fit and maintain.  It is easy to clean, completely chemical free and eco-friendly.  It is also extremely low cost (each unit is available to purchase at  £49.95 exclusive of VAT and P&P) and replacement is only required every 6 months (replacement cartridges cost £39.95 +VAT & P&P). All these unique benefits save you money (an average of £433 per urinal every year, in many cases much more) whilst keeping your washrooms hygienic and fresh.
