AstralPool Norm main drain for concrete pool, 47 m3/h

Main drains are a vital part of an inground swimming pool's drainage circulation system. In the pool's deep portion, drains ensure flow, assuring water cleanliness, optimum chemical distribution, and keeping a steady temperature of the water throughout the pool.

The pool water flows into the pump and filter through the main drain. The deepest area of the pool's bottom holds the location of the main drain. A smaller pool may only have one main drain, while larger pools may have several.
