Sylvan;
It is interesting that you discount a pump as the only way to increase pressure, but then admit that the only way to get water up to a gravity tank, once its height exceeds the limit of the city pressure is to use a pump. If the gravity tank is at the limit of the city pressure, then its pressure to the system will be EXACTLY the same as if the faucet were attached to the city system. You are so interested in being pedantic that you do not think about what you are writing.
