Have you ever wondered how clean water stays safe in your plumbing system? One important device working behind the scenes is the backflow preventer. Whether you’re managing a home, commercial property, or industrial facility, this small yet powerful device ensures contaminated water doesn’t mix with your clean water supply.
In New Zealand, backflow prevention is not just a recommendation—it’s often a requirement. Contaminants from irrigation systems, toilets, or even bidets can flow backwards into your clean water if not properly controlled. That’s where a backflow preventer comes in. Let’s explore what it does, why it’s important, and whether your home or business needs one.
What Is the Purpose of a Backflow Preventer?
A backflow preventer is a device designed to stop water from flowing backwards into your clean water supply. This is especially important in situations where contaminated water could pose health risks if it re-enters the drinking water system. Whether it’s fertiliser from a garden hose or waste from a bidet, backflow can happen more easily than you think.
The purpose of a backflow preventer is to:
- Protect your home’s drinking water from contamination
- Meet local plumbing and health regulations.
- Prevent health hazards caused by cross-connections
- Ensure water safety for households and businesses.
- Maintain public health standards across water networks
At UR Plumber, we’re experienced in installing and maintaining backflow preventers for both residential and commercial systems. Our experts can assess your needs and recommend the best solution.
