We had a burst main outside on Saturday. We lost water for about three hours, and it was a bit brown for a few hours when restored. We carry 4x 25 litre water barrels for emergencies. Half of one came in handy. We have a syphon too , to make water easy to access.
To be honest, we were more concerned that we might get flooded when the main burst- it was a lot of water! Thankfully, we have a HOB ( HOtel Bag) that we can utilise if we need to evacuate. Dog friendly hotels only!
You will come across the Bugout Bag, but don’t worry, it’s not mandatory.
