Do not rely on Aquaguards fixed inside coaches of this train, they seldom work. Found only 2 Aquaguards working in whole train, even if you tweet the same to RailMinIndia still it won't be rectified, they just forward it to IR Mechanical Dept, ultimately no one bothers for it, so my advice carry your own water for drinking purposes.
Toilets remain clean & water also is available.
