I attached the manual of the faucet I am about to install.
It doesn't indicate you need any kind of putty or silicone for the faucet base. They do have indicate the drain needs putty with a little picture.
Normally, the water won't make it up the base? Or maybe the base is rubbery, but the faucets I had before with similar setup is hard plastic.
If you think I need silicone or putty, please tell me where to apply it.
It's going onto a porcelain sink.
