Giant Overflow Siphon DN150

Giant Overflow Siphon with odour trap and optional rodent barrier.

Regular overflowing of the rainwater tank is essential as it prevents the formation of surface particles which reduces oxygen diffusion. This keeps the water fresh by stopping any anaerobic decomposition from taking place.

Also available with high-grade stainless steel rodent barrier.

Ideal for use in large-scale installations.

The 3P Giant Overflow Siphon’s outlet fits any DN 150 pipe.

The overflow siphon must be securely attached to the tank, since it has a substantial weight when filled. The Giant Overflow Siphon has several connection points in order to fasten it inside the tank. A high-temperature resistant (HT) DN 50 pipe can be attached to the bracing point to act as a supporting bracket.

Tanks fitted with 3P Overflow Siphons and 3P Calmed Inlets become eligible for the ECA scheme.

The Overflow Siphon removes dirt particles and debris which float on the water’s surface.

Regular overflowing of the cistern is essential for a high water quality. The Overflow skims the top layer enabling oxygen diffusion at the water surface.
