Water Seepage DIY Inspection Tips
To solve the water seepage problem, the first step is to identify the source of the seepage. Before seeking professional assistance, you can use the following simple methods, ensuring that they do not damage the building or sanitary fixtures. Along with regular observation and recording of any changes in the seepage situation, pay attention to the location of the seepage, the level of moisture, any odors, and discoloration to identify possible causes or sources of the seepage.
Color Water Test
Flow Meter Test
Back Pressure Test
Emergency Waterproof Measures
- Mix powdered or liquid color dye into water
- Each test requires about 10 liters of colored water
- During the test, simulate actual water usage by injecting the colored water into the pipes that carry water
- Observe whether any colored water seeps out at the corresponding leak locations; the process takes about one hour
- If testing for seepage from the rooftop, it may take about two weeks for the water to penetrate through the ceiling
- Turn off all faucets
- Record the reading on the water meter
- After 30 minutes, record the reading again
- Check if there is any change in the second reading.
- Record the number of drips at the noticeable leak location on the ceiling over a period of about 30 minutes
- Turn off the main water supply valve for the unit
- Open all faucets in the unit (including the faucet for the washing machine) to drain the water from the pipes and relieve the pressure in the system
- Record the number of drips at the leak location again over a 30-minute period until the dripping completely stops
- Turn on the main water supply valve and close all faucets, then wait for about one hour to allow the pressure in the pipes to reset
- Record the leak location and the number of drips over a 30-minute period again to repeatedly test for any leaks in the water supply pipes
Simple DIY water prevention at home starts with using waterproof sealant and silicone sealant for quick water stopping. The former is used to create a waterproof membrane, while the latter is used to fill connection joints and block the water source. Waterproof sealant is only suitable for outdoor use and should not be applied indoors or on ceilings (in areas affected by seepage), as it may trap water within the walls. It should be applied in at least two layers to ensure effectiveness.
Note: The above methods for seepage testing and waterproofing are only suitable for initial and minor issues. If the problem persists and worsens, it is essential to seek help from a professional.
