    Weefine Vacuum System detects air pressure changes inside your housing and tests the housing O-ring integrity pre-dive. Simply use the valve to pump air out from sealed housing and leave to stand for a minimum of 20 minutes. If the air pressure increases inside the housing, because of a leak, the unit warning light will flash.
