Delta Monitor cartridge replacement is actually fairly easy. Knowing how to replace a Delta shower cartridge is a valuable skill if you own a Delta Monitor shower faucet. Delta Monitor shower faucets prevent the water temperature from changing if someone else in your home decides to flush the toilet or run the dishwasher. However, no product, no matter how well designed or assembled, will last forever.
Therefore we will go over some of the basics of replacing a Delta shower cartridge.
To begin, find the set screw located in the base of the handle. You will need a small Allen key wrench to remove this screw. After the handle has been removed, grab the chrome sleeve and pull it straight out. You should not have to turn the sleeve, although a gentle side-to-side action may make it easier to remove. This will reveal a nut which must be loosened to be removed. Be very careful when removing the nut so as not to damage it. At this point you can pull out the old cartridge, thus completing your Delta shower cartridge removal.
Replace the Delta shower cartridge with a new one and reassemble the handle assembly in the opposite order that you removed it.
Be sure you follow the instructions and purchase the appropriate replacement part. However, if you damage the handle assembly when you are taking it apart, you may need to call a professional plumber to fix your mistake. Although it is natural to feel embarrassed, take the time to discuss what went wrong when the plumber arrives to avoid making a similar mistake in the future.
All-in-all the removal and replacement of a Delta Monitor shower cartridge can be a great job if you have the time, tools and know-how to finish the job correctly.
