McAlpine Anti Cross Flow And Rodent Barrier Valve Arb 1

General description The McAlpine ARB-1 is a 4"/110mm Anti Back-Flow and Rodent Barrier Valve designed to prevent sewage or wastewater from flowing back into a building's plumbing system, which could lead to contamination and health hazards. This valve is particularly useful for properties located in areas with a high risk of flooding or where there is a risk of sewage or wastewater backing up into the plumbing system. It operates by allowing sewage or wastewater to flow out while preventing it from flowing back in. Additionally, the valve includes a rodent barrier to prevent rodents and other pests from entering the building through the plumbing system, which is crucial in areas where rodents are common, as they can carry diseases and cause property damage.
