This video shows how to fix a leaky shower faucet by replacing a MOEN FAUCET CARTRIDGE. Great explainations and close-ups! Save money by doing it yourself. Very EZ! Anyone can do this. The cartridge in this video was bought at my local “big-box” hardware store. Model # is found on the old cartridge. OR… pull it and take it into the store for the match. Don’t buy a new faucet! Just replace the cartridge for a faction of the price. REALLY EZ!!!!
