bullseye mate you seem to be giving up far too easy mate
your in west mids just like me and it hasnt been that bad here mate.
you have to just get on with it, i worked 11- 3pm today got plenty
in just keep your hoses off the ground as poss when working and keep
the flow going try not switch off until you have finished job even if you
turn it down to a bare trickle water less likely to freeze up, i know its
a waste of some water but it will keep you going.
take plenty of rock salt out with you gives custies reassurance that
there will be no probs.
taking tank in all the time must be a ball ache,just get down the
local car wash and get some barrels fill up and take in overnight
