The butt was delivered with the instructions soaking wet and I had to carefully unfold and dry them out. The plastic bung to the planter disappeared down into the butt as I prised it open. Can't get it out as there is no access into the butt. Because of this, the instructions for attaching the divertor to the butt do not make sense, as they do not recognise this lack of access. With this problem, I have not yet taken the risk of installing the diverter to either the butt or the downpipe as I fear that if it does not work as it should, I could have a big problem with overflowing, or having to replace my 2 storey rainwater downpipe. It is much more attractive than my much cheaper, rather ugly, water butt but the diverter on this was easier to install and it was easier to check that the levels required for the system to work properly were correctly balanced.
