Overflow Outlet Straight Barbed Fitting 32mm

Overflow Outlet Straight Barbed Fitting 32mm (Reference: 100052) - This professional-grade technical accessory from Multitanks represents the ideal solution for efficiently managing surplus water evacuation in your storage installations. Specifically designed for 1000-liter IBC tanks but perfectly adaptable to any type of plastic reservoir, this overflow fitting guarantees optimal protection against overflows and ensures the longevity of your water collection system.

Applications and benefits

This straight barbed overflow fitting meets the needs of individuals concerned with optimizing their rainwater harvesting system, passionate gardeners managing their irrigation reserves, and professionals in the agricultural, horticultural or industrial sectors. It proves particularly useful during periods of heavy precipitation where water levels can quickly exceed the tank's storage capacity.

Installing this device helps avoid overflow risks that could damage foundations, create unwanted moisture areas, or generate inconvenience with neighbors. It also contributes to maintaining the quality of stored water by preventing stagnation and enabling natural content renewal during rainy episodes.

Technical specifications and design

Manufactured in high-quality polypropylene and polyethylene, this overflow fitting exhibits exceptional resistance to weather, temperature variations, and UV rays. These thermoplastic materials guarantee optimal longevity even under intensive outdoor use.

The 32mm diameter has been calculated to ensure sufficient evacuation flow without compromising the tank's structural integrity. The straight barbed fitting facilitates secure connection of flexible drainage hoses, creating durable sealing thanks to the barbs that firmly hold the hose in place.

Its compact design allows discreet integration on the tank wall, while its optimized geometry prevents the formation of stagnation zones that could promote microorganism development.

Installation and implementation

Installing this overflow fitting requires precise drilling using a hole saw adapted to the specified diameter. It is recommended to position the opening approximately 5 to 10 cm below the tank's upper edge, on a side wall to ensure easy access and efficient evacuation.

Before drilling, the work area should be thoroughly cleaned and the location precisely marked. Using a pilot bit allows for clean drilling initiation and prevents cracking. After inserting the overflow fitting, sealing can be reinforced by applying food-grade silicone sealant around the perimeter.

For evacuation, it is advisable to connect a flexible hose directing water to a natural infiltration area, storm water system, or second storage reservoir according to local regulations in force.

Expert advice and product synergies

To optimize your installation's efficiency, combine this overflow fitting with a suction strainer placed at the tank bottom to draw the cleanest water, and a tank cover to limit evaporation and prevent contamination.

Professionals recommend installing this type of overflow fitting on all IBC tanks used outdoors, even those equipped with properly sized collection systems, as exceptional weather conditions can exceed initial sizing predictions.

During winter periods, it is wise to check that the fitting and drainage hose are not obstructed by frost. Simple seasonal removal may be necessary in regions subject to prolonged freezing.

For professional installations, adding a backflow preventer upstream may be required according to local sanitary regulations, particularly if the tank is connected to the potable water network for top-up.
