Customer Questions & Answers

Question:
What is the Zurn Wilkins 12-375XL Backflow Preventer designed for?
Answer: The Zurn Wilkins 12-375XL is engineered to prevent backflow of contaminated water into the clean water supply. It is particularly suitable for use in commercial and industrial applications where heavy water usage occurs. This backflow preventer operates by employing a reduced pressure principle, ensuring that water flows only in one direction. For instance, it’s ideal for municipal water systems, irrigation systems, and heating systems, safeguarding water quality and meeting compliance with health regulations. -
Question:
How does a reduced pressure principle backflow preventer work?
Answer: The reduced pressure principle backflow preventer operates by maintaining pressure differentials. When the pressure drops in the system, it opens a relief valve, preventing contaminated water from flowing back into the drinking water supply. This mechanism is crucial in environments where backsiphonage is a risk, ensuring water remains safe for consumption. Scenarios such as irrigation or commercial kitchens benefit significantly from this technology, protecting public health and maintaining system integrity. -

Answer: The maintenance for the Zurn Wilkins 12-375XL includes periodic inspection and cleaning to ensure there are no blockages or debris causing malfunctions. It's advisable to check the valves and test the backflow preventer regularly, which is crucial for its optimal performance. For example, in a commercial setting, scheduling routine maintenance can prevent unexpected failures and ensure compliance, safeguarding water quality at all times. -
Question:
Is the Zurn Wilkins 12-375XL suitable for residential use?
