What does the water pressure coming into your house have to do with installing a water heater?

I live in a 20 year old house with 2 water heaters: one in the basement and one in the attic. The attic water heater started raining water into the bathroom below yesterday so we decided it was probably time to get a new one. Now the guy installing it tells me that in addition to the $299 installation fee, I also need to install flexible piping ($60) and that the water pressure coming into my house is too high and that they need to install a new water pressure valve for $199. I think they're ripping me off - I can understand the need for the new piping because the current water heater is connected with rigid copper piping, but I already bought an expansion kit to go with the water heater that I thought controlled the water pressure coming into the water heater. So do I really need to change the water pressure for the whole house? Not to mention the fact that I've always thought this house had terrible water pressure and I'm not too keen on bringing it down further. So can anyone tell me if this is something that really needs to be done?
