Why is copper used in water pipes but not on the taps?

Because copper is a soft metal, and in pipes it doesn't matter. If a tap was made out of copper as you can physicaly bend it you would mess up your tap! The reason it would mess up your pipes is because it filters the water through and it would strip all the copper of the taps and it wouldn't run anymore., Yes we are in year 8 at St Edmunds, and that automaticly makes us amazing :P Jesse and JD
