Step 1: Source/Origin

This is where the origin or source of leakage has been verified and identified from the positive side. It's the root from water IN, where rectification work to be done on the point of entrance.

This is a best permanent solution to rectified the leakage based on the 3 steps, that is why step 1 is of paramount important. It the most direct, efficient and affective among these steps. It is known as positive method of repair.

By rectifying the source of leakage, we are addressing the main leakage. It will be time consuming and costly if the source is not correctly indentified, leading to future further damage and repair.

With correct detection the first time and correct method statement for repaired. Time and cost will greatly be reduced and save. A temporary solution will resulted in reoccurred leakage if the source of leakage is not correctly identified.

The purpose of detection is to diagnose the origin of water leakage. Detection is a guessing work based on elimination with high percentage of correctness. The correctness from the deduction is based on experience and knowledge, it is a skill based on logic and fundamental.
