A good reminder.

We have a '3 way' water safety strategy in our off road set up.

More to prevent the potentially catastrophic risk of loss of water in very remote areas than to prevent internal flooding though.

1. Two separate water tanks - one in tow vehicle, one in van. The one in the van has both electric & hand pumps in case of power failure. . No power connected when driving.

2. Tank in car has access if loss of power. Taps are external. Inside there are stop valves for both hot & cold. These are turned off whilst travelling to prevent the tank being pumped dry if a tap or external hoses are damaged. (Unlikely, due to their position, but not impossible). We did however have a hot tap failure after 6 years on the road & just a few days before we got home. Tap would no longer turn off. Stop valve saved the day until tap could be replaced at home.

3.An on/off power switch for the pump on the circuit breaker board. Default is to have this switched off when driving, but there has been an odd occasion when we've forgotten.
