im changing over from a 350 to a 500 litre tank, with the 350 litre tank i just put the transfer hose into thetank via taking cover off and placing hoes into tank to fill.
the 500 litre tank seems higher etc. do many fit hozelock fittings into the tank body making it easier to fill. by just fitting transfer hose onto hozelock fitting.
if you know what i mean
any pics for ideas would be great
