A further new development is the water protection hose “…to make sure that the water is detained and diverted from protected objects with little effort. This hose is made of sturdy PVC coated polyester fabric, has a diameter of 400 mm and is filled with water from the network if necessary. He reaches to a height of 20 cm. The standard lengths are 2, 4, and 8 m.
After the water levels have declined, the hose over the inlet or exhaust valves is emptied again and can save space folded or rolled up.
