PVC Female Overflow Fitting 63x75

The PVC Female Overflow Fitting 63x75 (Reference: 100393) from Multitanks represents technical excellence for overflow management in your water storage installations. This professional device guarantees controlled and secure evacuation of excess water, thus preventing undesirable overflows that can damage your equipment and work environment.

Applications and benefits for your installations

This overflow fitting finds its place in multiple industrial and domestic configurations. For 1000L IBC tanks, it constitutes an essential safety element during filling, avoiding costly overflows and product losses. Agricultural professionals use it on their irrigation reservoirs to maintain optimal water levels without constant monitoring.

In the rainwater harvesting sector, this device enables automatic management of surplus during heavy precipitation. Communities and businesses integrate it into their temporary storage systems to prevent local flooding. Its female design facilitates connection to gravity drains or water recycling systems.

Technical specifications and materials

Manufactured in high-quality PVC, this overflow fitting resists UV, thermal variations and chemicals commonly stored in tanks. The 63mm diameter ensures optimal evacuation flow, while the 75mm outlet allows easy connection to standard drainage systems.

The integrated sealing gasket guarantees perfect impermeability even under pressure. Its composition in resistant elastomer ensures exceptional longevity even in permanent contact with water. The high-resistance plastic fixing nut allows optimal tightening without corrosion risk, unlike traditional metal solutions.

The smooth female design facilitates insertion into tank walls while uniformly distributing mechanical stresses. This technical characteristic considerably reduces risks of wall cracking during installation or in service.

Simplified installation and commissioning

Installing this overflow fitting requires only basic tools: a 63mm hole saw and a wrench for tightening the nut. First step: mark the overflow location at the desired height, generally at 90% of tank capacity to maintain a safety margin.

Cleanly drill the opening avoiding burrs that could compromise sealing. Insert the female fitting from inside the tank, position the sealing gasket then screw the fixing nut respecting the recommended tightening torque. Excessive tightening could deform the gasket and create leaks.

For evacuation, connect a 75mm diameter PVC pipe to your discharge point. Ensure a minimum 2% slope to ensure efficient gravity flow. A trap at the line end will prevent odor backflow if drainage goes to a sewerage network.
