You can fix this
Likely cause: a worn shower cartridge
A single-handle shower that drips from the head or spout with the handle off has a worn cartridge. Moen, Delta and others each name the cartridge to replace.
Why this happens
In a single-handle tub and shower valve, one cartridge controls flow and temperature, and its seals wear until water seeps past with the handle off. Moen's fix for a leaking Posi-Temp valve is the 1222 cartridge, and for Moentrol and Standard valves it is the 1225 or 1200. Delta's fix for a 1300 or 1400 Monitor valve leaking from the showerhead or spout is the RP19804. EPA notes a showerhead leaking 10 drips a minute wastes more than 500 gallons a year.
How to fix it
- Shut off the water to the shower at its stops, or at the main if it has none. Cover the drain so small parts cannot fall in.
- Remove the handle and trim, and identify the valve. Moen's three valve types look alike, so confirm yours on Moen's support pages before ordering.
- Pull the retaining clip or bonnet nut and remove the cartridge. Note how it faced.
- Install the new cartridge the same way and reassemble.
- Turn the water back on, check that the drip has stopped, and check the hottest setting with a thermometer. Keep it at 120F or less.
When to stop. If the cartridge will not come out, or the drip continues with a new cartridge, the valve body may be the problem. That is a plumber's job.
The part that fixes it
Match the cartridge to the valve: Moen Posi-Temp 1222, Moentrol and Standard 1225, Delta 1300/1400 RP19804, Delta 13/14 RP46074. Pfister and Kohler cross-references come from retailer listings.

If this does not fix it, tell the plumber
- It is a single-handle tub and shower that drips from the head or spout with the handle off.
- The valve brand and type if you know it, or a photo of the handle and trim.
- Whether the shower has its own stops, and whether you already replaced the cartridge.
