In the harsh winter like now the main reason we still can go to work with wfp is simple but a lot of folk don't realise the obvious, me to until told.
Mŷ hose reel and manifold and a choice of pole, I take a 30 ft, and place all three in the house over night, my reel can quickly be replaced and clamped bk down, connection of the manifold hose is seconds and the pole speaks for it self
And off to work we go, we have a 1000 lt tank in the vans and no way will you get a ice cube that big, it would have to minus 20 odd even to start freezing.
Most other things are frozen but the 3 things I need are not, ever since 3 years ago I've done this and never stopped me in my tracks, don't need heater, for good measure I place a hot water bottle in the enclosed pump department just to keep it warm for a few hours.
This only takes place in the minus 1 or below.
Hope it will help any one out
That is all lol
