The Stefani Float Valve prevents lower chamber overflow. * Simple to install. * Effectively doubles your Stefani Water Purifiers capacity!
After the candle is installed, simply screw the Stefani Float Valve onto the end of the filter. The Stefani Float Valve will rest in the bottom chamber, thus the top chamber can be continuously filled without overflow occurring between the tow chambers. If the Float Valve does not fit to the end of the candle or leaks, cutting off 4mm (approx.) of the candle.
