Sure, but.. I've been coding for 40 years and I don't know everything. To me, a LOT depends on what the plumber asked chatgpt about. For example: building codes in that city, to figure out what his options are - like, is he allowed to just put in any old toilet, or is there a gpf restriction? What's the replacement part number for faucet XYZ's gasket? Those seem reasonable.
"how do I fix a clogged toilet?" would be bad..
