Carlos is the man. There was some confusion with scheduling but Carlos showed up and did the job. He installed my Aquasana system, installed my new Moen kitchen faucet, fixed a leaking outdoor spicket and replaced a part in my toilet that turns out to have been installed improperly by the people who switched out the toilet when I had purchased my home.
Carlos even had to hurry to Home Depot to get the part for my toilet (before they closed) and he did so and was cool about it.
Now I have clean drinking water and all my plumbing issues have been fixed, all for a great price.
