PVC Female Overflow 32/40

PVC Female Overflow 32/40 (Reference: 100396) - This professional overflow system is an essential safety component for all water storage installations. Designed by Multitanks, this superior quality fitting ensures controlled evacuation of excess water, preventing potentially damaging overflows to your environment and equipment.

Applications and benefits of PVC overflow

This PVC female overflow 32/40 is essential in numerous water storage configurations. For homeowners, it secures rainwater collection tanks, garden ponds and garden reservoirs against overflows during heavy rainfall or excessive filling. Professionals use it on their industrial, agricultural or construction installations to protect process tanks, fire reservoirs and irrigation systems.

The dual 32/40mm compatibility offers remarkable usage flexibility, allowing adaptation to different pipe diameters according to your installation constraints. This versatility eliminates the need to multiply stock references and simplifies maintenance.

Technical specifications and composition

The 32/40 overflow kit consists of three complementary elements: a smooth PVC female fitting machined with precision, a flat gasket ensuring perfect sealing against the wall, and a resistant PVC nut for tightening. The selected PVC material exhibits excellent resistance to common chemical agents, UV rays and temperature variations.

The smooth female design facilitates PVC glue connection, guaranteeing a permanent and perfectly watertight bond. The 32 and 40mm diameters correspond to European PVC piping standards, ensuring optimal compatibility with existing networks. Wall thickness and dimensioning have been calculated to resist static and dynamic pressures encountered in storage applications.

Installation and implementation

Installing this overflow requires precise drilling of your tank wall using a hole saw at the exact diameter of the fitting. Position the overflow at the desired height to determine the maximum water level in your reservoir. Place the flat gasket against the internal face of the tank, insert the fitting from outside and tighten the nut progressively to compress the gasket uniformly.

The drainage pipe connection is made by PVC gluing with suitable glue. Prepare surfaces by light sanding, degrease, apply glue on both elements and fit immediately while performing a quarter turn. Respect drying time before commissioning.

Maintenance is limited to periodic verification of sealing and possible cleaning of the drainage conduit to avoid blockages by plant debris or sediments.

Expert advice and optimization

To optimize your overflow efficiency, direct the outlet toward an appropriate outlet: existing drain, retention basin or infiltration area. Avoid direct discharge onto impermeable surfaces or against foundations. A downpipe with elbow will avoid turbulence and reduce flow noise.

Combine this overflow with our other tank accessories: drain valves for maintenance, S60x6 fittings for IBC tanks, or suction strainers to avoid debris aspiration. A pressure gauge installed on your circuit allows pressure monitoring and overflow anticipation.

Beware of common errors: oversized drilling causing leaks, excessive tightening cracking the PVC, or positioning too low reducing useful volume. In freezing zones, insulate the overflow or partially drain the tank to avoid bursting from ice expansion.
