Last night we noticed brown water coming out of all three cold taps in the house (kitchen, and two bathroom). This morning all three are clear.
This is very confusing because I understood the kitchen tap to be fed directly from the main pipe, and the bathroom taps to be fed indirectly from the storage tank in the roof.
Can anyone explain why all three went brown, and then cleared almost straight away, all at the same time. Does this mean that all three are being fed from the mains, or from the tank?
Many thanks for any advice!
