Is the system safe for home pool use? Yes, this jet operates on a safe voltage of below 30V, making it very safe for the human body. This system is specifically designed for home pool use.

Typically, for children practicing swimming, a flow below level 7 is sufficient, while flow rates above level 7 can accommodate regular adults' leisure swimming.
