All our water butts are empty. Have tried sloshing buckets of water down the stairs to outside. Not fun.
Our neighbour has just given me his old pond pump. All I have to do is shove it in the bath with a hosepipe connected. Aim the hose pipe at the water butt from the bathroom window and turn on the pump.
Only after a trial session I've decided it will take two of us until I've refined the system. Plug is in bedroom, can only see/aim hose from loo room (next to bathroom) and pump musn't run dry so also need to keep an eye on the bath.
The result of trying to coordinate activity in all 3 rooms was quite spectacular. I don't think the neighbours were expecting their garden to get watered
