We use water that we buy at the supermarket for brushing teeth, coffe and cooking and local water for the potable water tank, when we have food in a restaurant I ask for agua mineral de Penafiel, and I request that it not be opened when it is brought to the table, if opened I send it back, beer is handled the same way un-opened.
A filter may not work in some plases due to very low pressure on the lines, we have taken showers where there was only a small trickle, and to get water in the RV I had to do it with the 2 gallon jug that I carry and use the gravity inlet.
