The answer is absolutely YES, if the water is coming into your home or business discolored, has a foul stench and sometimes a grainy feel and of course the unseen calcium. It is not good for you to drink or for your water applicances (toilets, sinks, washing machines and showers) especially where rubbers can be cut from the sand like sediment causing a leak into the toilet or a pebble keeping the valve open and the water is running on the inside. You will notice that your shower head a white at the tips and also clogged.
