Certikin Stainless Steel Main Drain Grille Kit To be added on pools where direct foot contact is made eg: Paddling Pools, Learner pools, Plunge pools.

  • With a brand new mould and taking advantage of improvements in technology since 1968 (when the original Certikin Main Drain was first made) the new Certikin Main Drain has the same consistent quality as the other Certikin ABS white goods.
  • 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.

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.
