Indoor drains with a Neptune float


Our company has developed a unique system for street and floor drains, which is called Neptune. If the water level drops, or if the siphon dries out, the float will close the drain outlet to prevent the back flow of odour from the sewage line. One may often encounter odours when entering a room whose drain siphon does not work properly or got dried. The Neptune float is manufactured in two sizes, both for street drains and for floor drains as well. These floats are not interchangeable. They work reliably up to 70°C.
