Many water purifiers have a direct connection with tap or pipes that are used to fill the container. This leads to a lot of wastage of water and the accumulation of water on platforms if you have a small hose connected to the water purifier. I have an OTG and a mixer blender placed on my platform, once such an incident spoilt my mixer as water was collected under the mixer which I didn't notice even after cleaning the platform.

I would recommend to read which water purifier is best for home, understand your needs and install the right water purifier with containers and taps.
