Oh boy, I have to say changing faucets is my absolute least favorite activity, I actually asked my granite guy if we could somehow rig a hinge so that when I have to service the faucet we can just lift the counter like a hood, he said "NO", it would be cheaper to hire the most expensive plumber in the world everytime the faucet needs servicing... Which made sense at the time...
I would rather change a toilet in a strangers house than change one of the faucets in my master bathroom, the vanity has them tiny double doors with shelves around the plumbing, and deep under mount sinks with everything in the way, its a nightmare, thats why when I buy faucets I buy the absolute strongest best well made unit money can buy, because I don't ever want to change it...
Even if you are not a trademan, if this is the tool they invented to make it easier, you can imagine how much the job sucks to do...
Anyway Alex here is Mandy to teach you how to get er' done... there is a 30 second advertisement before the video but its worth it...
