Considering this, can you install a mixer tap yourself?

How do pull down taps work?
The pull-down kitchen faucet works by allowing the spray head to extend down into the sink. You turn the water on using the single handle as usual. At the same time, you can mix the hot and cold water using the same handle. The water from the handle goes back down to the main controller unit under the sink.
