I was cleaning out under the sink and happened to look at the plumbing.......if I ever have to change out the Moen I will have to cut the copper lines to remove it. When this thing was built (2004 Safari 25B) whoever plumbed it left the PEX hot and cold a little short, so rather than make the PEX lines the correct length, they just bent the living hell out of the copper, wrapped the hot side around the outlet line to the rinse sprayer. Used some high quality Vise Grips to do this little surgery, lines are so crushed and kinked that any attempt to move them will break them. If you're buying a new one, make sure you look under the sink, for that matter, have them open all the trim/access panels and have a look see.
