We have braided hose on the washer as well. Another thing we do, most especially when we travel, but between washings when we think of it, is to turn off the faucets between washings.
We also have a pan under the water heater with a hose running outside in case the heater leaks, which it did once, or the pressure relief gives way. You can buy water heater overflow pans where you buy water heaters.
