i guess you use a sub pump to move the water to your van / s
so why not just connect some hose from the IBC taps, open the taps and you have them connected
job done
I dont think they would flow fast enough between the 2, I have to empty and fill 1300L in about 20 mins
your IBC tap will be 1" output, so use a 1" pipe, have a go, all you need is the 1" pipe that you can buy by the meter at B&Q
I dont any fixing for the taps Matt, they have a screw thread on them, I need the fixings to go on them I already have the hose
are i see
measure the thread on the IBC tanks
pop along to " plumb center " or whatever your local plumbing place is called
ask them for a fitting to screw into it, you will then be able to connect the pipe to that fitting, you might need the fittings to reduce the pipe to something you can fit a hose over, the bigger the dia the better though
