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.

On commercial or shallow pool applications stainless steel main drain grilles must be used. 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.
