Our bathroom is very small, but it is indoor plumbing. The sink is directly across from the toilet. The water pressure has been good. We understand the water turns brown when the tank gets low, so we run the water in the washer before we add the clothes to be sure the white ones won't come out brown. So far, no brown showers.
We have a water filter for our drinking water. We have to wash all vegetables and fruit before we eat them in the water from that tap. We are glad we don't have to boil water. We have been drinking more pop than we should just because we know it is safe. We have bottled water at the office.
