The apparatus includes a coupling for connecting an external water supply, at least two check valves to enable water to be added from either the external water supply or a water tank onboard the truck, and a meter for recording water added to the concrete drum. Separate hoses may be provided for adding water to the drum and for supplying water for use outside the concrete drum.
