Surface drainage and maintenance access to ensure smooth drainage
Our 4-inch maintenance hole cover has two main functions: one is the surface drainage function, which ensures the smooth operation of the drainage system and reduces water accumulation; the second is to serve as a maintenance channel. It is located above the drain outlet of the atrium or flower bed and can serve as a safety mechanism when the drain outlet is blocked, making it easier to clear the obstruction. It is recommended to use an industrial vacuum cleaner to remove it. It is especially suitable for atriums or flower beds with fill height greater than 50cm, providing all-round protection for your drainage system.
