The Importance of Proper Breather Installation for Rainwater and Cartage Tanks to Ensure Performance and Warranty Coverage

As more individuals and businesses embrace sustainable liquid storage practices like rainwater harvesting and mobile water cartage, it is essential to prioritise proper breather installation procedures. One critical but often overlooked aspect of maintaining poly storage systems is the installation of breathers within any water tanks that feature secure, sealed lids.

Whether you are utilising a rainwater tank equipped with sealed lids or a heavy-duty cartage tank for transport, ensuring the presence of a proper breather is vital. It is not only key for achieving optimal water flow and pressure performance but is also a mandatory requirement to maintain your manufacturer warranty coverage. In this guide, we will explore proper installation and maintenance practices that will help you protect your investment and secure your tank’s warranty.

Why Do Rainwater and Cartage Tanks Require Breathers?

Breathers serve a crucial role in regulating atmospheric air pressure within poly water tanks, preventing dangerous vacuum buildup during high-volume water extraction with a pump. This is particularly important in domestic and commercial rainwater harvesting systems, where rapid water extraction can cause sudden changes in air pressure within the sealed vessel. If air pressure is not properly equalised, the resulting vacuum can cause severe tank deformation, tank collapse, pump cavitation, and will void your structural warranty.

In transport and cartage tanks, breathers play an identical role in regulating internal air pressure, ensuring that the tank remains structurally stable and secure during high-speed transport and rapid discharging on-site. Neglecting breather installation in these mobile environments can lead to structural failure, product damage, and immediate voiding of your warranty coverage.

Specific Requirements for Breather Installation

The specific requirements for breather installation vary depending on the ultimate purpose of your tank, the type of pumping system integrated, and the extraction rate employed. For example:

• Rainwater harvesting systems: Breathers may need to be installed in conjunction with a first flush device or mosquito-proof screens to ensure that only clean, pest-free water is extracted from the rainwater tank.
• Cartage tanks: Breathers must be installed in specific, elevated locations on the tank to prevent vacuum buildup while avoiding water spillage or sloshing during transport.
• Pumping systems: The flow rate of your pumping system directly dictates the size and quantity of breathers required to handle the displacement volume safely.

Risks of Neglecting Proper Breather Installation

Failing to follow correct breather installation guidelines can lead to severe operational issues and permanent damage, including:

• Vacuum pressure buildup: Negative pressure can restrict outflow, strain your pump motor, and lead to pump damage and reduced system delivery performance.
• Airlock formation: This can trap air inside the pipework or tank fittings, blocking water from flowing freely into the tank or out to your discharge lines.
• Structural tank damage: Without proper ventilation, the suction force of a pump can literally implode a poly tank, compromising its structural integrity beyond repair and voiding all warranty entitlements.

This serves as a critical reminder of the role breather installation plays in safeguarding your warranty entitlements and preserving the structural longevity of your investment, whether for rainwater harvesting or agricultural spraying and transport. Neglecting this simple fitting could not only void your warranty but also compromise the efficiency of your water management systems.

Sourcing the Right Breathers and Fittings for Your Tank

While some poly tanks may come with integrated breathers, additional venting accessories might be necessary depending on the water extraction rate and pump size employed. It is your responsibility as the tank owner or installer to verify the adequacy of the breather system to uphold warranty integrity and ensure long-term performance.

For commercial clients and industrial projects, pressure regulation and accessory placement are best addressed at the design phase. Through our comprehensive design to manufacturing service, we work closely with clients to engineer custom tanks with precision-engineered breather and fitting provisions. Leveraging state-of-the-art CNC capabilities (which include advanced 3D printing for rapid prototyping and validation), we ensure that every single tank is manufactured to the highest standards. This capability has made Global Tanks an industry leader in custom OEM rotomoulding across Australia.

At Global Tanks, we recognise the importance of proper breather installation for both rainwater tanks and heavy-duty cartage tanks. While we can facilitate high-quality breather supply, it’s important to note that we do not provide final guidance on size or quantity. This is due to the variability in pumping systems and extraction methods utilised by different users. However, our team remains fully committed to assisting you in sourcing the necessary breathers to meet your specific requirements.

Protect Your Warranty with Correct Breather Installation

In conclusion, whether you are utilising rainwater tanks or cartage tanks, attention to detail during installation is what guarantees long-term durability. By ensuring proper breather installation, you are not just protecting your physical investment and maintaining warranty compliance; you are also contributing to the efficiency and safety of your water storage practices.
