Helpful information on installing your downpipe
  • The water butts do not come predrilled. This product is very easy to use and can be drilled in by anyone. Simply attach the drill bit onto your drill and begin drilling – remember you must drill the hole in the water butt at the same level as the hole in the downpipe!
  • As long as the holes drilled in both the water butt and the downpipe are level, the water butt will continue down the downpipe when the water butt is full.
