Hi WendyW, thanks for your suggestion. Unfortunately (or do i mean fortunately, i can't decide) our water discolouration is intermittent. Some days, you can turn on the tap and get virtual mud. The rest of the time it looks clear, but still tastes foul. As 5029 says, it's a matter of taste - a Waterboard official could come to my house and say "That tastes fine to me" but he'd be lying. But how can you prove it? My waterfilter makes it drinkable, and i'm satisfied with that. If i run a bath and the water turns brown halfway through, i just pull the plug out, run the tap until the water turns clear and then start running the bath again. I used to live in London, and i guess i got spoiled by the quality of the water you get round there. I've moved to "The Sticks" for a bit of peace and solitude, and i guess you have to pay a few penalties for the privellage. (not being able to get broadband for one!) I'm prepared to put up with my water quality (or lack of it) for now, as with a waterfilter and a little patience you can work around it. Thanks for your helpful suggestions, they are appreciated. Sorry moosefly, i didn't mean to hi-jack your thread!
