All RBT vaporizers are designed to be a handled vaporizer and has not been tested with water tools. Customers may choose to use RBT vaporizers with water tools but should be aware that there might be interference issues with the heater screen. Although the heater screen is robust, it can be forced out of position creating a crevice where debris can collect and potentially damaging the heater. Care should also be taken to not support the unit by the heater glass as undue stress can crack the glass or break the bond between the heater glass and the wood. The heater itself has proven impervious to water spills but the electronics compartments, knob and switch should not get wet.
