Negative Positive
Title: Not consumer friendly
Review: I live in a region where the water is very hard with lots of carbonate dissolved salts. Within a very few years all of my Moen faucets began sticking. I've replaced several cartridges with new ones and they did the same thing. These faucets were not leaking, just sticking. Upon closer examination of the cartridge I see it is composed of two main parts: the outer body of the cartridge and an inner stem. I tried an experiment and lubricated the rubber "O " rings of the inner stem with silicone grease and also the outer ' O ' rings and rubber inserts on the side of the cartridge. I reinstalled the old cartridge and it worked like a charm for several years when I had to repeat the procedure. Save the cost of a new cartridge if your faucet is not leaking and just buy some silicone grease and lubricate as instructed above.
Is the review positive or negative?
