Main Drain Selection Guidance:

When selecting the appropriate sump (main drain) size, it is crucial to consider the total flow that may be directed to the plant room via the sump(s). The sizing of the sump should align with the expected flow ratios, with adjustments made for Skimmer type pools (70% Surface/30% sump) or Deck Level pools (50% Surface/50% sump). In commercial or shallow pool applications, stainless steel main drain grilles are mandatory for compliance and safety.

For optimal safety and performance, it is recommended to install at least two main drains positioned 2 meters apart to minimize the risk of entrapment and ensure efficient water circulation.
