I also asked the guy at Alright plumbing and he said that i couldnt use a different combination. Not sure how true that is, as im fairly new to the plumbing business. Guy at home depot referred me over there cause they didnt have that style at home depot
I'm only a second year apprentice but I was just trying to find something similar for a customer last week and it was a very old delta. Was not in any of the box stores. We luckily have a local specialty store with an old guy that probably knows every faucet cartridge and stem ever made
You right. They do sell it. The associate who works in that isle there must have never seen one. I searched the area also but didnt see one but sure enough its there at my nearest Home Depot. They got 12 of them as it shows online.
