3P Giant Overflow Siphon DN 150


Operating principle

Dirt particles, which are lighter than water (e.g. pollen) float on the water‘s surface.

The design of the Overflow Siphon ensures it removes the floating debris. 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.

Giant Overflow Siphon with odour trap and suction of the surface water.

No passing for rodents because of high grade stainless steel rodent barrier.

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

Ideal for use in large-scale installations.

The overflow siphon must be securely installed into the tank, since it has a substantial weight when filled. If the water level is very low, the lifting power is missing.

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.
