Finally got some time to install a new kitchen and RO faucets. Here you can see the finished product. The RO faucet needed an air gap so I found this one with good reviews on Amazon.

Here are the original faucets. The kitchen faucet has a terrible design in that the handle just channels water down the back of the faucet when you go and turn it off with wet hands. Then the water just collects on the counter. You can see the water ring around the faucet.

Here's the RO faucet. It started rusting at the handle and would leak water every time you turn it on.

My working quarters. After moving all the plumbing drains etc. it actually wasn't too bad to work in.

Here's a closeup of the build up in the drain pipe just after the trap. I didn't expect this would be there. This is probably 10 years of build up.

You can see the old valve stop I removed plus the drain gunk. You just turn them counterclockwise while pulling and they come right off. I put in proper 1/4 turn valves.

Here's a closeup of the hard water buildup on the counter.

Here's after I removed the hard water with a razor blade scrapper. It makes easy work of the build up.
