There is a water tank on the roof. Can you hear the sound of hitting the wall at night?

Water tanks are divided into six types according to materials: glass fiber reinforced plastic water tank, stainless steel water tank, stainless steel liner glass fiber reinforced plastic water tank, seawater glass fiber reinforced plastic water tank, enamel water tank and galvanized steel water tank. The water tank is generally equipped with HYFI remote liquid level electric valve, water level monitoring system, automatic cleaning system and self-cleaning sterilizer. The overflow pipe of the water tank is connected with the drain valve of the water tank and is equipped with an insect-proof net. The water tank should have two ventilation pipes with different heights (equipped with insect-proof nets), and the water tank should be equipped with internal and external ladders. Water tank generally includes water inlet pipe, water outlet pipe (domestic water outlet pipe and fire water outlet pipe), overflow pipe and drainage pipe. According to different functions, water tanks are divided into five types: domestic water tank, fire water tank, production water tank, civil air defense water tank and domestic water tower. Strictly speaking, toilet flushing water tank and car water tank are not water tanks.
