Siphons and calmed inflow

Siphons and calmed inlet - clean, calm and odour-free water in the tank

Siphonsand calmed inlet are advanced rainwater tank accessories that guarantee clean, odour-free water and minimise sediment agitation during filling. The calmed inlet controls the water flow, preventing swirling turbulence, while the overflow siphon effectively separates surface debris, also trapping odours from the sewer.

The Aquatechnika range includes:

  • Calm Inlet DN100 - made of polyethylene, prevents sediment agitation and oxygenates the water at the bottom of the tank, which maintains water quality and freshness,
  • DN100 overflow siphon - dedicated to plastic and other tanks, protects against backflow and provides an emergency drain in case of overflow,
  • Filter kit components - on some models (e.g. Supra) the calmed inlet and siphon are integrated into a compact filter solution, minimising contamination.


These products are robust, simple to install and are ideal for domestic rainwater systems as well as garden or industrial installations.

Choose a solution tailored to your tank and enjoy clean, odour-free water.

The siphons and sedated inlets are constructed from durable materials such as polyethylene and plastic components for corrosion resistance and long-lasting performance. The calmed inlet oxygenates the water at the bottom, which prevents the development of anaerobic decomposition processes, while the overflow siphon traps surface contaminants and protects against odours. In filter kit offerings, such as the Supra, both elements are integrated into the stainless steel filter cartridge, creating a practical and condensed form of water quality protection.

Applications for siphons and sedated inlet

  • Maintenance of water purity in tanks - no sediment agitation,
  • Protection against unpleasant odours backing up from drains,
  • Natural oxygenation of the water at the bottom, preserving its freshness,
  • Safe emergency drain in case of overflowing of the tank (in siphon version),
  • Aesthetically pleasing and functional finish to installations in homes and gardens.

FAQ - questions and answers

What is a sedated infusion and why should it be used?

A calmed inlet is a special inlet for rainwater tanks that disperses the water flow, preventing swirling turbulence and the mixing of sediment with domestic water. This keeps the water clean and saturated with oxygen, extending the life of the entire system.
0

What is the overflow siphon used for in rainwater systems?

The overflow siphon allows gravity drainage of excess water and traps unpleasant odours from the sewer. It also acts as an overflow safeguard to prevent sewer backflow.
0

What do we gain by using both solutions at the same time?

The combination of sedated inlet and overflow siphon provides comprehensive protection: keeping the drinking water clean, fresh and safe, minimising odours and enabling controlled overflow in crisis situations.
0

Is the assembly of these components complicated?

No - both the sedated inlet and overflow siphon feature a simple design and easy installation. They are designed to be installed quickly even without specialist support, speeding up the start-up of the system.
0

In which installations will these products work?

They are indispensable for domestic and garden rainwater tanks, but also for retention and storage systems. Wherever water free of sediment, odours and overflow problems count - a siphon and calmed inlet will work effectively.
