Hi,

I have just bought a 'Rainsava' rain diverter
http://www.raindrain.ltd.uk/index.html and will be fitting it to my Sankey
Space Saver water butt. The Water Butt has some flat indents intended
for incoming hose connection around 3 inches from the top lip.

However, if I fit the RainSava as directed
http://www.raindrain.ltd.uk/How.html, the connection will need to be made
about 2 inches lower where the wall of the water butt is ribbed making
connection difficult.

I have sketched a couple of diagrams showing the method in the instructions
(A) and my preferred method (B) http://tinyurl.com/2jrxmx

Am I correct to assume that fitting the RainSava a little higher than
specified so that the connector is level with the 'flat indent' will cause
an overflow? I would have thought that the water would level out where the
connection is made and then not fill the butt any further with more rainfall
(thus creating an automatic 'overflow' system)?

Thanks in advance for any advice,

Kroma

If you just move everything upwards by the amount needed to get the
outlet from the Rainsava exactly at the same height as the flats on
the butt, you will be OK. The key to these water diverters is that
when the butt is full, the water just backs up along the pipe to the
diverter and flows on down the drainpipe. But the inlet to the butt
must be at the same height as the outlet from the diverter in order
for it to work properly. Your diagram B looks correct.
