This is actually our second Insinkerator Hot/Cold faucet. Our first one lasted about 15-16 years before needing to be replaced. I'm sure anyone with basic plumbing knowledge could install this, especially as a replacement, but since we had a plumber coming to fix some other issues, we had him install this too. I love having instant hot water for my tea. This unit bypasses our water softener so it's our go-to for any drinking.
