Hi everyone,
I have a question about what happens when the incoming mains water valve with the arrow on it has water flowing backwards rather than forwards. For example the arrow on the water stop valve is pointing left but the water coming in is going right instead of left, would this pose as a health concern at all?
Thank you for any information
