The Woody Valves kit is an extension hose for Woody drain. This kit adds an external ball valve to your Woody tub. It also has a hose connector for 38 & 32 mm ID hoses sold as extra. The supplied 50mm OD hose has to be glued with supplied PVC glue to the Woody drain elbow. The hose length is matched for Kirami Woody tubs so that the valve is fitted just outside of the tub wall.
