OK so having zero plumbing experience besides building a potato cannon out of PVC 20 years ago, I did this and it was pretty easy. You can buy the tank and stand off Amazon. You'll want to get a brass tee kit as well (this is what I got, make sure you size it correctly https://www.amazon.com/dp/B00TG27TGG?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_6&th=1) If you are using pex, DONT use sharkbite fittings. They will all leak, eventually, and you can get a crimp tool and fittings for fifty bucks. Watch some youtube videos and you can figure it out. You'll want some blue monster plumbing tape and pipe dope - i like to use both. Tape first, then a little dope. This is for connecting the brass tee. After that, you can transition to PEX but you want that part hard piped
