guys we know wfp in commercial is no prob but when it comes to domestic then that is another dilemma
we use backpacks but the water suppy is limited as we carry 12 litres instead of 20 litres to reduce weight on the back, I place a container on the sack trolley and use that for top up, but again the water supply is not that great and you need to keep topping up.
so thought about this -- backpacks are coming in from the usa and getting cheaper all the time, what about a cart with say about 3 or 4 backpacks in a pull trolley and instead of topping up you just transfer the backpack and carry on cleaning, would the time saved fulign up offset the cost over the year say
would the backpacks not give you backup as well if one broke down
just food for thought any views greatly appreciated
