Imagine turning on the tap, expecting clean water, and getting something harmful instead. It’s a scary thought, but without backflow preventers, it’s a risk.
According to NIH, Only 20% of Pakistanis have access to safe drinking water. That’s why we at GreenTech Solution care about your water safety. We provide backflow prevention services to keep your home or workplace water clean, protecting you and those you care about.
Backflow happens when water moves backward. It is typically as a result of variations in water pressure. The pure water supply may get contaminated as a result of this. Pump failures, pipe breaches, and excessive water use are common causes
Backflow is the unwanted reversal of water flow in your plumbing system. This can contaminate your clean drinking water with dangerous substances like sewage, chemicals, and other harmful materials.
Backflow preventers are essential devices that block this reversal, safeguarding your water supply.
Water can only flow in one way thanks to a backflow preventer, which stops any reverse flow. Check valves and air gaps are used to keep contaminants out of the clean water system
BACKFLOW PREVENTER | CHECK VALVE |
Prevents contamination of water supply | Prevents reverse flow in a single direction |
More complex with multiple valves | Simple one-way valve |
Required by code in many locations | Not always required |
Used in high-risk situations | Used in low-risk applications |
Higher due to complexity | Lower, often more affordable |
Choosing the right backflow preventer depends on the level of hazard posed by the cross-connection, as determined by your water authority:
The most reliable prevention method. It creates a physical air space between potable and non-potable systems (think of a faucet above a sink). Protects against a wide range of hazards, including backpressure and back siphonage
Protects against low or high hazards under back-siphonage only. Has a simple design with an air valve and check valve to block contaminated water.
Similar to AVB but also includes spring-loaded valves, shutoff valves, and test cocks enabling field testing. Also protects against low or high hazards under back siphonage only.
Mostly used for fire protection. Two spring-loaded check valves, shut-off valves, and test cocks protect against low hazards under back siphonage and back pressure.
Offers maximum protection, common in fire protection systems.Works similarly to a DCVA but adds a relief valve for extra protection, creating a reduced pressure zone and air gap.
Protects against both high and low hazards under both back pressure and back siphonage.
You likely need a backflow preventer if:
Yes, fire protection systems must have backflow preventers. This guarantees that public health is not jeopardized. Sprinkler systems need water as it is required to extinguish fires. This keeps stagnant water out of the pure water supply.
If backflow of water occurs, this would contaminate the whole water supply and result in disease and other problems.
It depends on the type:
Important: Building codes usually require backflow prevention devices. Older homes may need a backflow inspection and updated equipment to prevent contamination.
Not sure what to do?
If it is so, then it’s always safest to call an expert. They can diagnose the problem and make sure your backflow prevention system is working correctly to protect your water supply.

Commitment to Water Safety: Defending the quality of water poured to you is our number one blow.
Stopping polluted water from returning to the pure water supply is the goal of a backflow preventer.
Yes, you need a backflow preventer to protect your water supply from pollution.
A backflow valve or RPZ (Reduced Pressure Zone) valve is another name for a backflow preventer.
The purpose of the backflow function is to stop water from flowing backwards, which could pollute the clean supply.
In a nutshell, Backflow preventers are vital to preserving the purity of water, which is essential for health and well-being.
Our specialty at GreenTech Solutions is installing premium backflow preventers, which shield your water supply from harmful contaminants.
