I have just installed my kitchen tap and the water has a strange taste to it

If after installing your new tap your water has a strange taste to it this is usually because of the new flexible hoses.

The flexible hoses are usually made from braided steel and inside of the hoses are rubber pipes, it is usually the rubber pipes that cause the water to have a strange taste. After several days of use as water is continually flushed through the taste should disappear.
