Product Description

This Rock Bay Check Valve prevents back siphoning of water into your air pump. An essential for marine aquariums, it prevents water from being sucked into your air pump in the event of a power failure, which can cause serious damage. Always use a check valve whenever your pump is placed at a lower level than the top of the aquarium. Do not use it on the outlet side of an ozone generator.
