A pipe test is a diagnostic process that uses an external pipe attached to the existing waterfall pump to identify the location of a leak. Here's how to carry it out:
Purpose:
- The test allows you to systematically isolate sections of the stream to locate the area where the leak occurs.
- It prevents unnecessary disturbance to parts of the stream that don’t need repair, saving time and effort.
Step 1: Determine Baseline Water Loss:
- With the pond and stream running as normal, measure how much water is being lost over 24 hours. This will give you a baseline for comparison during the test.
Step 2: Set Up the External Pipe:
- Attach an external pipe to the existing waterfall pump.
- Run the pipe above ground, starting at the pond, with the water returning directly back into the pond.
- Let it run for 24 hours and measure water loss. If there’s no water loss, the leak is likely further upstream.
Step 3: Test in Increments:
- Move the pipe upstream in 5–10 foot (1.5–3 meter) increments.
- At each position, let the system run for 24 hours and monitor the water level.
- Continue this process until you detect water loss equivalent to the baseline measurement taken during normal operation.
Step 4: Pinpoint the Problem Area:
- Once you identify the section of the stream responsible for the leak, focus on that area.
- Carefully remove rocks and other features to locate the exact source of the leak.
Notes:
- This process may take several days, as each section needs to run for 24 hours to ensure accurate results.
- Though time-consuming, this method minimizes unnecessary disruption to unaffected areas of the stream, saving significant effort and resources.
By systematically isolating sections of the stream, you can efficiently identify and repair the leak without unnecessary damage to the entire water feature.
