Cleaning the filter
When the water pressure becomes low or insufficient, the filter will need to be cleaned.
1. Close the water inlet valve to stop water supply.
Note:
Do not remove the filter without closing the valve. Otherwise, water will spray out.
2. Remove the T valve filter.
Unscrew the connector using a spanner and then remove the filter. Refer to the images
below.
