This is what Very Dark Man said
"For those of you saying you need Faith for the water to work, you are shallow minded. Anything you buy with your hard earned money does not require faith to work".

You cannot go to the market and buy a TV and need faith for it to work, you don't buy medicine from hospital and need faith for it to work.
True Miracles are not Transactional.
The moment you pay for it, it becomes a service and it is expected to work.
