Mt Bibo started dripping not only from the outlet but alos the pipe at the bottom. Apparently this requires a clean. I ordered a cleaning kit which was originally sent to my home address not my work as requested so I ended up having to collect it from Halfords. I could then not unscrew the stopper in the top of the cleaning cylinder using the key provided. A replacement was sent pre-loosened. After cleaning the leakage is worse if anything so I shall have to try this again as a new tank is not included under the warranty.. As I have the UV light and filters delivered automatically it would be nice if the cleaning solution could be included with this.
