I just replaced a cartridge on Delta sink tap that was leaking a bit of water on the counter top. The guy at Home Depot told me both Delta and Moen had lifetime warranties so we rummaged through his supply of cartridges he had in the back room. I found one that looked similar but wasn’t convinced it it would fit. It contained the cartridge plus the spring and washer that sits below it. He gave me that one for free. We then went over to the plumbing section and I picked out a cartridge that looked identical along with the spring and rubber washer, (sold separately). Funny, it was in a Moen branded package.
Unfortunately I lost the little grey spacer that limits the motion of the handle. It must have fallen out as we were handling the original cartridge.
Long story short, I ordered two cartridges from Amazon.ca that come with the spacer and I cleaned up the original cartridge and re-installed it with the spring and washer from the free cartridge kit he gave me and a spacer from an identical tap in the lower levell bathroom that has two sinks. The cartridge itself was the wrong one. The new ones are on the way. I’m returning the Moen cartridge.
Here is the “stoopid” spacer that went missing.
