Could someone enlighten a non technical person about what fittings i can
get, that will enable a plastic garden water tank to be drained by
connecting it (securely and non-leaking) to a 20 metre length of standard
(1/2") garden hose please.

Open the top, stick in hosepipe until it hits the bottom, pull up a little
bit, place end of hosepipe lower than the base of your tank, shove hosepipe
in your mouth and suck.
Spit out shit and drain.
Dead easy.
