HH I suspect that the problem in this case is the throttle effect of the outlet from the tank as opposed to the pressure drop along the length of the hose. Whilst it would be possible to raise the tank and/or increase the diameter of the hose (or employ one with a smoother internal surface) in order to improve the rate of flow within the hose, that doesn't improve the rate of flow into the hose from the tank in this instance.
“It's still magic even if you know how it's done.”
raisingirl you are exactly right and with a tap bore that is usually restrictive on these tanks you struggle to get any decent pressure even when elevated.
We use to use them set about three or four meters off the ground with a direct S60 x 6 or S100 x12 outlet for testing and back flushing of new pipe work on low pressure systems 10psi or less.
Anything else then it was water tankers and pumps.

Well it's just taken me 4-5 mins to fill my watering can up with a 2m len di it 3 times. A pump that fits through the top hole might be ideal but nothing I seen so far fits, but would also have to be cost effective as I'm already £150 into this.

If you go for this make sure you use an 30mA RCD for protection against electric shock.
