I changed my Kitchen tap - now the water tastes awful !!! - Any Ideas

Does the water look contaminated in any way when viewed in a glass?

What would you say the water tasted of?

Maybe there is some grease or something inside the tap?

Sparks...

I'm guessing you live in a hard water area and the last tap was scaled up inside :) I reckon it's the inside surface of the tap or the pipes, that you can "taste". Or possibly some leftover flux, sealant or lubricant is flavouring the water. If you do live in a hard water area it will scale up eventually and the problem should hopefully go away :)

You should have chosen a tasteless tap.

Sorry, couldn't resist ;-)

How long is "some time"? Could it be that the mixing is done at the tap end of the spout rather than at the discharge end - and that the spout remains full of water, some of which will have come from your hot tank? If so, you will need to run enough off to empty the spout before using it for drinking.

I suppose it *could* be that, even in the cold position, some hot water is coming through. If so, the taste would always be there, even after you have run it for a while. Have you got service valves on the hot and cold feeds to the tap? If so, turn the cold feed off and operate the tap on "cold" and see if any water comes out. If it does, that's your problem.
