The bottom drain made of fibreglass 490 × 490 mm is a built-in part installed in the pool floor, which serves to drain the pool, circulate the water or as a safety element preventing the suction entrapment of users. The frame size of 490 × 490 mm with a d110 mm connection is the standard for medium-sized to large pools with a concrete or fibreglass base.
The fibreglass design guarantees high compressive strength, resistance to corrosion and chemicals used in the treatment of pool water. The material is light and easy to work with, which facilitates correct installation into the pool floor during construction or renovation.
The bottom drain is suitable for private and commercial pools and meets the safety requirements for the maximum flow velocity through the grate to minimise the risk of suction entrapment. We recommend combining it with a corresponding grate of DN 110 diameter for a complete and safe solution.
