In stock, immediate despatch
This overflow tank is compattable with the entire range of Borg and Overstrum b2 and b3 water coolers.
Rather than having to keep emptying the drip tray you can fit an overflow waste kit to your b4 water cooler.
Perfect for high flow areas, an audible alarm will sound when the tank needs emptied.
This does not fit inside a countertop b4 but is installed in a cupboard below the cooler.
