PVC Female Overflow 50x63

PVC Female Overflow 50x63 (Reference: 100394) - The professional Multitanks solution for controlled evacuation of excess water in your storage installations. This complete overflow fitting guarantees secure evacuation and prevents accidental overflows from your water tanks, reservoirs and cisterns.

Applications and uses of PVC overflow

This PVC female overflow 50x63 adapts perfectly to the needs of individuals for their domestic installations: rainwater harvesting, water storage for irrigation, pond or natural pool supply. Agricultural professionals use it to secure their irrigation tanks, watering troughs and storage reservoirs.

In the industrial sector, this fitting finds its place on IBC 1000L tanks, process reservoirs and water treatment installations. Its robust design resists intensive use constraints and pressure variations. Installers appreciate its ease of implementation and compatibility with existing PVC networks.

Technical design and materials

The overflow fitting consists of three essential elements: a smooth female PVC fitting with 50/63mm diameters, a flat gasket ensuring sealing and a PVC tightening nut. This modular design allows secure assembly and easy disassembly for maintenance.

The high quality PVC used resists UV, thermal variations (-10°C to +60°C) and corrosion. The smooth interior surface minimizes pressure losses and facilitates flow. The smooth female fitting allows double connection: 50mm or 63mm PVC pipes according to evacuation flow requirements.

Precise dimensions guarantee perfect compatibility with European plumbing standards and Multitanks equipment. The integrated anti-return design prevents unwanted water backflow.

Installation and implementation

Installation begins with precise drilling of the tank wall with a hole saw adapted to the fitting diameter. Position the overflow at the desired height, generally at 3/4 of maximum capacity to maintain a safety reserve.

Assembly is performed in three steps: insertion of the female fitting from inside, positioning of the flat gasket against the external wall, then tightening the PVC nut without forcing to avoid excessive stress. Manual tightening is sufficient to ensure sealing.

The evacuation pipe connection is performed by PVC gluing with specialized glue. Clean and degrease surfaces, apply glue uniformly and fit firmly. A 24-hour drying time is recommended before commissioning.

For maintenance, periodically check the gasket condition and nut tightening. Annual cleaning eliminates limescale deposits and maintains optimal flow.

Expert advice and optimization

To maximize your installation efficiency, correctly calculate evacuation flow according to supply section. A 63mm pipe suits high flows (intensive irrigation, rapid filling), while 50mm is sufficient for standard domestic uses.

Combine this overflow with Multitanks accessories: shut-off valve to control evacuation, PVC reduction to adapt different diameters, oriented elbow to direct flow. A tank inlet filter prevents obstruction by debris.

Professional tip: install two overflows at different heights to create a staged system. The first signals approach of maximum level, the second ensures absolute safety. This configuration is ideal for critical installations.

Beware of common errors: drilling too large causing leaks, position too low reducing useful capacity, forgetting gasket causing infiltrations. Follow installation instructions for optimal service life.
