A Chronicle of Garden Water Fountains
A Chronicle of Garden Water Fountains Pope Nicholas V, himself a learned man, governed the Roman Catholic Church from 1397 to 1455 during which time he commissioned many translations of ancient classic Greek texts into Latin. It was important for him to embellish the city of Rome to make it worthy of being called the capital of the Christian world. Starting in 1453, the ruined ancient Roman aqueduct known as the Aqua Vergine which had brought fresh drinking water into the city from eight miles away, underwent restoration at the bidding of the Pope. The ancient Roman custom of marking the entry point of an aqueduct with an magnificent celebratory fountain, also known as a mostra, was restored by Nicholas V. The Trevi Fountain now occupies the area previously filled with a wall fountain built by Leon Battista Albert, an architect employed by the Pope. The Trevi Fountain as well as the well-known baroque fountains found in the Piazza del Popolo and the Piazza Navona were eventually supplied with water from the altered aqueduct he had rebuilt.Keeping Your Outdoor Garden Fountain Tidy

No more than three-four months should really go by without an extensive cleansing of a fountain. The initial task is to get rid of all the water. When you have done this, scour inside the water reservoir with a mild detergent. Feel free to use a toothbrush if helpful for any stubborn crevasses. Make sure all the soap is properly washed off.
Various organisms and calcium deposits can get inside the pump, so it is recommended to take it apart and clean it completely. Letting it soak in vinegar for a few hours first will make it much easier to clean. If you want to remove build-up in your fountain, use rain water or mineral water versus tap water, as these don’t contain any ingredients that might stick to the inside of the pump.
Finally, be sure to have a quick look at your fountain daily and add water if you see that the level is low. Allowing the water to reach below the pump’s intake level, can cause severe damage and even make the pump burn out - an undesired outcome!
