is the water dirty, if so its coming of your sink..
if its clean =the fill valves will be faulty...
best way to check what one is.....
switch of cold vave under sink...if you still get water then you will know its the hot as its still turned on...
hot valve are the most common for this...
if you need any spares drop me a email
