If you think the hose that feeds water to your Surf Splash II might heat up in the sun after extended periods of sun exposure, you may want this convenient device to purge the hot water from the hose prior to use. With proper use this will prevent Surf Splash users from being burned when they step onto the unit. The unit comes with a diverter but must be turned on/off manually. This enables you to purge the hot water without bending over. Simply step on the handle until all the hot water is purged and step off. It’s that simple!
