Overflow Fitting Straight Barbed 50mm

Overflow Fitting Straight Barbed ø50mm (Reference: 100054) is an essential safety accessory for any water storage installation, specially designed for 1000-liter IBC tanks. This reliable drainage system ensures optimal management of excess water and protects your equipment against overflow risks.

Applications and main benefits

This overflow meets the needs of individuals and professionals using rainwater harvesting systems. It proves indispensable for farmers, gardeners, livestock breeders and green space managers who operate large capacity tanks. The 50mm barbed fitting ensures efficient drainage even during heavy rainfall, thus avoiding overpressure and potential damage to the storage structure.

Its use also extends to industrial installations requiring precise liquid level control, automated irrigation systems and emergency water reserves. The versatile design allows adaptation to different types of plastic tanks beyond standard IBCs.

Technical specifications and materials

Manufacturing in polypropylene and polyethylene guarantees exceptional resistance to weather, UV and corrosion. These thermoplastic materials offer remarkable durability over time, maintaining their mechanical properties even when exposed to extreme climatic variations.

The 50mm diameter straight barbed fitting allows secure connection with standard drainage hoses. The barbs ensure perfect sealing and facilitate hose insertion while guaranteeing solid hold without risk of accidental disconnection. The straight design optimizes drainage flow by minimizing pressure losses.

The complete kit includes a specially sized sealing gasket and a tightening nut allowing reliable fixing on tank walls of variable thickness. This modular design facilitates maintenance and allows selective replacement of components if necessary.

Installation and commissioning

Installing this overflow requires determining the optimal positioning height on the tank, generally located at three quarters of the total capacity. Use a hole saw of appropriate diameter to drill the side wall, being careful to deburr the edges thoroughly to ensure perfect sealing.

Position the supplied gasket between the internal wall and the overflow body, then insert the assembly from inside the tank. Screw the nut from the outside by tightening gradually to avoid gasket deformation. Moderate but firm tightening ensures sealing without damaging the plastic materials.

Then connect the drainage hose to the barbed fitting, using a hose clamp to secure the connection. Direct the drainage toward an appropriate drainage area, maintaining sufficient slope to ensure gravity flow. Check sealing by gradually filling the tank to the overflow level.

Expert advice and optimizations

To maximize system efficiency, install a leaf filter upstream to avoid fitting obstruction by plant debris. This precaution is particularly important when using with gutters connected directly to the tank.

Consider installing multiple overflows at different heights to create a tiered system allowing finer water level management. This configuration proves particularly useful for installations requiring a permanent minimum reserve.

Association with our Multitanks valves and fittings allows creating complex distribution systems. Combine with our submersible pumps to completely automate stored water management. Gardena irrigation timers from our range integrate perfectly for automated irrigation.

During freezing periods, protect the installation by partially draining the tank below the overflow level. This precaution avoids mechanical stresses linked to ice expansion that could damage the sealing.
