Current recommendations state that every pool should have at least two Main Drains. Therefore, at least one Main Drain on every pool will need the bottom port sealed off – that’s why the new Certikin Main Drain body has a knock-out blanking plate in the bottom port to save you time and money on site.
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 a minimum of 2 main drains are installed 2 metres apart.
