Kohler faucet

Since my older sister transferred to her new house last 2007 she was able to use two different kinds of faucets already. I don’t know if it wasn’t properly installed but they are all out of order now. It’s either there’s a leaking or the handle is easily torn. A leaking faucet can always damage her water bill. When I visited my sister’s place and saw her problem, I told her to use Kohler faucet because surely it will last for 20 years or more.
