Additional Information

  • Recommendation – Main drains must be arranged so that there is no risk to 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.
  • All pipework and pool fittings must be pressure tested before backfilling and commissioning.
  • These fittings should not be used in water depth of less than 0.9 metres.
