Hi everyone,
Finally I have figured out what the two stop cocks in the kitchen do as they both had to be replaced due to leaks.
The one under the sink stops the cold water from coming into the kitchen tap and the one which is in the wall panel is connected to the incoming mains water and needs to be fully turned on as before it was turned most of the way clockwise (previous people who lived in flat saw a leak and rather than fix/replace the stopcock it was turned a majority of the way clockwise which stopped the leak) the plumber told me it should never be turned in the opposite direction of the flow of water which it previously was which may explain itchiness and skin rashes all over my body every time I used the kitchen cold water for drinking or cooking and as of getting the issues fixed last month the rashes are clearing up.
My first question is: Does anyone know what happens when mains fed water goes in the reverse direction instead of the right direction where the arrow is on the check valve? Does that mean that the water is contaminated or mixing with the neighbours as I worry that it poisoned my body?
I live on the top floor flat and have two neighbours below me in a block of 6 and we share the incoming mains fed water pipe from the street which comes into our building, would I need anything such as a NRV or check valve to prevent any chance of backflow or contamination, as I want everything to be above board and not worry about water mixing with my neighbours or reverse flow.
I have a mixer taps throughout the flat and isolation valves fitted on each pipework.
