Baz, I am running a training course on bucket filling, give me a call. It's a pretty comprehensive course covering all aspect's of filling, from tap filling to exterior filling from your wee wee and will also cover what to do in the instance of overfill, focusing on mopping up technique. There is also a section on safety when bucket filling. The last thing any of us want to do when filling the bucket is to kick the bucket.
It's a two week course with certification at the end, so no worries!!
You have come to the right man my friend. Get in touch to book now.
