4. Setup and Installation

This tub spout is designed for a slip-fit installation onto a 1/2-inch copper pipe extending from the wall. Ensure the pipe is clean and free of debris before installation.

Tools You May Need:

• Allen wrench (often included or required for set screw)
• Sandpaper or abrasive pad (for cleaning copper pipe)
• Plumber's grease (optional, for rubber seal)
• Rag or towel

Installation Steps:

1. Turn off Water Supply: Locate and turn off the main water supply to your bathroom or the entire house to prevent water flow during installation.
2. Remove Old Spout: If replacing an existing spout, loosen any set screws (usually on the underside) and pull the old spout off the copper pipe. Clean the exposed copper pipe thoroughly with sandpaper to remove any mineral deposits or corrosion.
3. Prepare New Spout: Inspect the inside of the new Moen spout for any rubber seals or O-rings. Applying a small amount of plumber's grease to these seals can aid installation and prevent damage.
4. Install New Spout: Align the new spout with the copper pipe. Push the spout firmly onto the pipe until it sits flush against the wall or tile. Ensure the spout is level.
5. Secure Spout: Locate the set screw on the underside of the new spout (if present). Use an Allen wrench to tighten this screw against the copper pipe, securing the spout in place. Do not overtighten.
6. Restore Water Supply: Slowly turn the main water supply back on.
7. Check for Leaks: Turn on the faucet and check for any leaks around the base of the new tub spout. If leaks occur, turn off the water, re-check the installation, and ensure the spout is fully seated and secured.

5. Operating Instructions

The Moen 3808P tub diverter spout is simple to operate:

• Filling the Tub: To fill the bathtub, ensure the diverter lift rod is in the down position. Water will flow directly from the spout into the tub.
• Using the Shower: To divert water to the showerhead, pull the lift rod on top of the spout upwards. This will redirect the water flow from the spout to the showerhead.
• Returning to Tub Flow: Once the shower is turned off, or if you wish to return water flow to the tub, the diverter lift rod will typically drop back down automatically. If it does not, gently push it down.

6. Maintenance and Care

Proper care will help maintain the polished brass finish and ensure the longevity of your Moen tub spout.

• Cleaning: Clean the spout regularly with a soft, damp cloth. For stubborn spots, use a mild soap and water solution. Rinse thoroughly and dry with a soft cloth to prevent water spots.
• Avoid Harsh Cleaners: Do not use abrasive cleaners, scouring pads, ammonia-based cleaners, or any cleaners containing bleach, acids, or harsh chemicals. These can damage the polished brass finish and void the warranty.
• Prevent Mineral Buildup: In areas with hard water, wipe down the spout after each use to prevent mineral deposits from forming.
