Main Drain Selection
When choosing sump (main drain) size always assume that total flow may be directed to the plant room via the sump(s) - sump size should be chosen accordingly. In normal conditions flow will be divided between surface draw-off and sump(s) in ratio: 70% Surface/30% sump for Skimmer type pools or 50% Surface/50% sump for Deck Level pools.
Important - On commercial or shallow pool applications stainless steel main drain grilles must be used.
Recommendation - Main drains must be arranged so that there is no risk of bathers being drawn towards them or trapped there. It is recommended that on all installations, including domestic, a minimum of 2 x main drains are installed 2 metres apart.
