Fountain rule
Allow us to introduce you to the fountain rule, it is called the "J.W rule"
The J.W rule states that the height of water emanating from a fountain / water feature jet should be no more than 50% of the diameter of the pool in which it sits.
This is because water will fall as far as it is high.
So for example if you have a pool that is 4 M* across if you have a jet that is 4 M* high in this pool that means water can fall 2 M outside of the pool. Obviously over time this will empty the pool. this applies to ANY pool.
There are certain "Exceptions" such as if you have a large surface, such as a rock or wall where the water runs down its surface, or wind controls to reduce jet height.
When designing a fountain this rule must be taken into consideration
................... Correct
.......................................... Incorrect
Notes:
If a fountain has multiple jets each jet should be no higher than its distance from the edge. e.g. a 30cm low jet should be at least 30cm in from the pool edge.
If this rule is not adhered to the pool will run dry, burning out the pumps.
A) Where water Can fall
