Troubleshooting High Water Usage
If you’ve noticed a sudden increase in your water usage or
are concerned about your consumption, follow these steps to investigate
possible causes.
Step 1: Confirm Your Water Usage
To determine whether the increased consumption is a new or
ongoing issue, follow these steps on your meter keypad:
- Check
Your Updated Balance:
- Press 604 followed by the red enter button on the meter keypad to reset
the connection and display the correct available balance.
- Press 600 followed by the red enter button to view the total units used.
- Review
Your Purchase History:
- Check
your token purchase history for the past 3 - 4 months to see if
your usage has changed.
- Copy
the date and token value into a spreadsheet to calculate
your total monthly usage.
- Ensure
all purchased tokens have been correctly loaded onto the meter.
If your purchases and usage have increased, you can perform
self-checks before requesting further assistance.
Step 2: Self-Checks for High Water Usage
1. Checking for ‘Ghost Usage’ (Unexpected Water
Consumption)
- Take
a photo of your meter's available balance or total usage.
- Turn
off the main water valve to your unit overnight or for at least an
hour.
- Reopen
the valve and check if the balance has changed:
- If
usage increased while the valve was closed, this may indicate that:
- Your
meter is swapped with another unit’s meter.
- The
meter is tracking usage incorrectly.
2. Verifying Meter Calibration
- Take
a photo of the available balance or total usage.
- Use
a measured amount of water:
- Fill
a 5L container or flush the toilet (8–10L depending on the
model).
- Compare
the recorded usage on the meter:
- 5L
should register as 0.005 units.
- If
the reading is incorrect, the meter may require recalibration.
Step 3: Check for Common Household Leaks
Before requesting a technician, check the following
potential sources of water loss:
Dripping Taps or Running Toilets – Even a slow drip
can significantly increase consumption.
Geyser Leaks – Check your geyser (if accessible) for any visible drips.
Pressure Control Valve (PCV) Leaks – Inspect the main shut-off valve for
any leaks. A small drip can worsen when a tap is opened.
Step 4: When to Request a Technician
If your self-checks indicate a potential meter issue, you
can request a technician to inspect or replace the meter.

Important Note:
- The
water meter is not owned by STss. If the installation is out of
warranty (beyond one year), the cost of a replacement meter will be
charged to either the unit owner or the scheme, depending on ownership.
- If a
technician is dispatched and the cause of high usage is found to be one of
the common issues listed above (such as a leaking tap, running toilet, or
geyser leak), the call-out fee will be for the owner's account.
