Pretty straightforward install, but takes up a little space. Took me about an hour and a half, start to finish. Not sure if it's common, but I'll get reimbursed for the cost because I live in third world America and the lead content of my water is high.
Oh, yeah, love the boil notices, always a good sign. I've done a lot of plumbing in the past year. The plumbing wasn't too bad, but the drywall repair was miserable after.
