General Preparation

Prior to installation, it is essential to review the full set of provided instructions and diagrams to understand the assembly flow. A common recommendation is to install the mounting hardware on the wall and work backward to align components correctly. The following steps should be taken prior to installation:

1. Turn off the water supply to the installation area to avoid water damage and complications.
2. Verify the rough-in fitting is properly installed in the wall, aligned with the incoming water lines.
3. Check the copper tubing to ensure it is the correct nominal size (1/2″), is clean of burrs, and has been cut to the appropriate length.
4. Assemble the faucet components either separately on a clean work surface or directly on the wall, depending on access.

Failure to follow these preparatory steps may lead to improper installation and potential damage to the faucet or surrounding wall structure.

Mounting Spout Installation

The mounting spout is one of the foundational components of the Delta T3558LF-WL faucet system. Proper assembly and alignment of the spout are crucial to prevent leaks and ensure a secure fit against the wall surface.

Installing the Spout

The installation steps for the spout involve several small but critical components to create a watertight seal:

1. Install gasket (2):

   • Place the provided gasket over the cut end of the copper tubing before sliding the spout onto the pipe.
   • The gasket serves as the primary seal to prevent water from escaping at the joint.

2. Slide the spout over the copper tube (1):

   • The spout is designed to slide over the copper tubing and should be aligned so that its base is flush with the wall’s surface.
   • Ensure the spout is perpendicular in orientation and securely seated on the wall.

3. Tighten the set screw (3):

   • The set screw is typically located at the bottom of the spout and is used to secure the entire assembly.
   • Tighten the screw manually until it is snug; do not overtighten, as excessive force may damage the internal O-ring or gasket seal.

4. Check for leaks:

   • Once the spout is installed, verify that the set screw is sufficiently tightened but not binding in the threads.
   • After installation, no additional adjustments should be required unless specific system flushing or maintenance is necessary.

Important Notes

According to the manufacturer, it is essential to ensure the cut end of the copper tube is free from burrs or nicks prior to installation. Any imperfections in the copper can compromise the integrity of the seal and cause water leakage. Users who notice rough edges on the copper should re-cut or file down the end before proceeding to install the gasket and spout.

Handle Installation

Once the spout is mounted and secured, the next phase of the installation involves assembling and attaching the handle. This step is crucial for ensuring the faucet operates smoothly and the controls are correctly aligned.

Assembly of the Handle Components

The handle assembly includes several parts that must be installed in a specific order:

1. Remove and discard the plasterboard (optional):

   • If the wall surface includes a removable backing such as plasterboard, it should be removed and discarded if not required for mounting. This allows the handle components to sit flush with the wall.

2. Install the sleeve (1):

   • The sleeve serves as a securing component that fits into the wall cavity or over the spout body.
   • Slide the sleeve onto the wall pipe or mounting area as specified in the manual.

3. Install the handle flange (2) and gasket (3):

   • The flange is used to fasten the handle to the wall surface and must be aligned with the sleeve.
   • A gasket is installed between the flange and the wall to prevent water from seeping through the connection.

4. Cap (4):

   • The cap covers the handle flange and provides a finished appearance.
   • Tighten the cap manually and ensure it aligns properly with the handle flange.

5. Handle (5) and Security Components:

   • The handle itself must be attached to the internal stem and secured with a hex wrench.
   • A button (7) is also included for added stability and alignment. This is inserted into the screw hole to prevent loosening during use.

These steps ensure the handle assembly is structurally sound and functional, while also providing a clean and professional appearance.

Final Connect and Leak Test

Once the spout and handle are installed, the final steps involve connecting the faucet to the water supply and performing a leak test to identify any issues before full use.

Connect Water Supply

The water supply should only be connected once the faucet is fully assembled and all components are in place. This involves:

1. Reconnecting the water lines:

   • Open the shut valves at the plumbing rough-in if they were previously closed. Do not assume that all water connections are already open.
   • The faucet should already be connected to the rough-in via the copper tubing and internal valves.

2. Verify connections at the handle and spout:

   • Recheck the internal spout connection and handle valve system to ensure all tightening mechanisms are engaged and no debris is obstructing the flow path.

3. Open the supply valves fully:

   • If the water supply has been closed for installation, open the valves slowly to allow air and water to flow through the system.

Leak Test

A critical step in final installation is the system flushing and leak test. The user should:

1. Remove the aerator (1):

   • The aerator is the small nozzle at the base of the spout. It should be removed if not installed during the final flush.

2. Turn the faucet handle (2) to full-on position:

   • Open the handle fully and let water flow through the system for one full minute. This step ensures that any internal particulates or installation residue are flushed out of the lines.

3. Reinstall the aerator (1):

   • After the flush, the aerator must be reattached to prevent large contaminants from entering the faucet.

4. Check all connections for leaks:

   • Inspect the set screw, gaskets, spout-to-wall joint, and the base of the handle flange for any signs of water leakage.
   • Any leaks should be addressed by adjusting the relevant components or replacing damaged seals.

5. Adjust or tighten as necessary:

   • If the faucet leaks under the handle, the bonnet nut (1) can be tightened. If the leak persists, the cartridge (2) may need to be replaced.
   • For low flow conditions, the user should clean the aerator (3).
   • If the spout itself leaks at the wall, the O-ring (4) may need to be replaced.

These steps are essential to confirm the successful and reliable operation of the Delta T3558LF-WL before regular use.

Maintenance and Troubleshooting

Even the most carefully installed Delta faucet may require maintenance over time. Regular inspection and simple cleaning can help extend the lifespan and functionality of the faucet.

Cleaning the Faucet

Despite its durable finish, the T3558LF-WL requires gentle cleaning to avoid damage. The manufacturer provides the following instructions:

• Use a damp cloth to wipe the surface and handle.
• Avoid abrasive cleaners or polishes, as these can degrade the finish.
• If grime or debris builds up in the handle or spout, a mild liquid soap may be used in a non-abrasive manner.
• Always blot the surface dry with a soft towel to prevent water film buildup or rusting of internal components.

Failure to clean the faucet properly may lead to stains or discoloration that can compromise both aesthetics and function.
