I have a one handle Moen faucet and the handle slowly falls down when you turn it on. How do I tighten this?

Check the picture out below.

You will need to remove parts 3 (plastic cap) and 2 (allen screw) and then work your way down to the cartridge as needed. See if anything has chipped or broken off inside the unit.

If it has, call 1800buymoen and request a new part under warranty if faucet is not too old. You may need to visit the website to get the part number www.moen.com (http://www.moen.com) Otherwise, a local plumbing supply house can order the part for you more quickly!

If nothing obvious you may need to replace the entire cartridge assembly (part #13).

Let me know what you discover...
