a) First of all, check the Tata Swach fuse. If the top red indicator touches or is near to the bottom red indicator, it is time to change to a new Tata Swach Bulb.
b) Otherwise, follow these steps: Please note that your Tata Swach Bulb is densely compacted with purification media comprising of activated silica coated with silver nanoparticles. While the dense compacting aids water purification, it may, over time, result in air getting trapped inside it, reducing, or even completely stopping the flow. Water will therefore flow through the Tata Swach Bulb as soon as the trapped air has been released. Following are the methods of releasing trapped air:
1. Remove the bottom mesh, as this would allow the trapped air to escape.
2. Drain out water from the lower container.
3. Fill the upper container completely with water to create the highest possible pressure head to help release the trapped air.
4. Gently tap the upper container. This would also allow trapped air to escape.
5. Wait for 25-30 mins.
6. Water should now start to come down in the lower container.
7. You can now fit the bottom mesh back to the bulb. Ensure that the bottom mesh is clean and it is fitted loosely to the bulb. (An unclean or an overly tight-fitted Tata Swach Bulb increase the possibility of air entrapment).
