Backflow Prevention Services in Dubai
We survey, fit and test backflow prevention on Dubai properties, from a single hose bib on a villa wall to the plant room of an apartment building.
Water is only pushed one way while the pressure holds. When the mains drops, because a main is repaired or a pump trips, the column can reverse, and whatever sits at the end of an open line comes with it. An irrigation dripper lying in wet soil. A hose left in a bucket. A chemical dosing pot on a cooling circuit. Each of those is a cross connection.
The remedy is a device matched to the hazard, not the biggest one available. A hose bib vacuum breaker where a hose is the only risk. A double check valve where an irrigation line joins the domestic supply. Then it gets tested, because a non return valve that has seized open protects nothing and looks identical to one that works.
