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!
If they all had the same symptom it surely means they come from the same
source - presumably the mains. If you turn off the stop cock on the pipe
entering the house (rising main) and this stops all cold water taps, then
there's your answer.
I agree with cerberus that it is probably caused by work being done on the
mains supply in your area. Usually the water board post letters to people if
it has been scheduled work, but it may have been an emergency.Have you
noticed any water board vans in the area.
Thanks everyone. I phoned water board to make sure it was their problem to
fix and not mine!! Yes there is some work somewhere nearby which might have
I think the conclusion is that all three taps must run off the mains and not
the storage tank. I am pleased about that because the tank has no lid and
is full of dead spiders, and inches of muck etc. I have always taken water
from the kitchen for that reason.
Simple way to check - Turn the tap on, and try to stop the water flow by
putting your thumb over the end of the tap. If you can, it's low pressure,
therefore a gravity feed from the tank. If you can't, and you squirt water
up the walls and curtains in the attempt, it's high pressure fed.
