How to Remove Air from Pressurised Water Lines

Understanding the Problem: Air in Water Pipes

If you’ve ever experienced noisy pipes, reduced flow, or unexpected system inefficiencies, trapped air is often the culprit. In pressurised water lines, air pockets can:

• Reduce system efficiency and increase pumping costs
• Interrupt smooth flow and create vibration or noise
• Lead to inaccurate meter readings or pressure surges
• Cause long-term wear on pumps, valves, and fittings

Left unresolved, air accumulation can compromise both performance and reliability

The Solution: Single Small Air Release Valves

The most effective way to manage this problem is by installing single small air release valves at key points in your pipeline. These compact, automatic valves are designed to continuously vent small quantities of trapped air as the system operates.

How They Work

• During operation, dissolved air naturally separates from the water.
• This air rises to high points in the pipeline, forming pockets.
• A small air release valve detects these tiny accumulations and vents them safely, without interrupting flow.

The result: a system that runs smoothly, efficiently, and with less strain on your equipment.

Why Choose a Dedicated Air Release Valve?

Compared with manual venting or ignoring the issue, a single small air release valve offers:

• Continuous protection – automatic, no manual intervention required
• Improved efficiency – reduces energy wasted in overcoming trapped air
• Cost savings – lowers risk of pump damage, pressure surges, and system downtime
• Longevity – protects fittings, seals, and other valves from unnecessary wear

Where to Install Them

Strategic placement is key. These valves are commonly fitted at:

• High points in the pipeline where air collects
• Downstream of pumps
• Long rising mains or sections prone to air entrapment

Correct positioning ensures maximum protection and return on investment.

Summary: Remove Air, Protect Your System

Trapped air in pressurised water lines is a hidden problem that can quietly drain performance and increase costs. A single small air release valve offers a simple, effective solution — automatically venting air, improving system reliability, and safeguarding your investment in pumps, pipes, and infrastructure.
