Single Handle Faucet Repair Guide

Faucet Repair Process Overview

This document details the steps involved in repairing a single handle faucet, specifically addressing the issue of a leak coming from the spout. The following sections break down the individual tasks, tools needed, and parts involved in the repair process.

Identifying the Problem

The central issue being addressed is a leak from the faucet spout. To effectively repair this, it's necessary to access and replace worn components within the faucet assembly.

Tools Required

  • Adjustable Wrench: A larger adjustable wrench is necessary to remove the handle cap of the faucet. This wrench must be wide enough to fit the cap securely.

Step-by-Step Repair Instructions

  1. Removing the Handle Cap:

    • Use the adjustable wrench to carefully remove the handle cap. Ensure to grip it firmly to avoid slipping.

  2. Removing Internal Components:

    • With the handle cap removed, gently take out the cam and packing along with the stainless steel ball assembly. This will expose the internal parts needing attention.

  3. Inspecting Existing Parts:

    • Upon inspection, you may notice hard water and rust deposits on the existing components. At this stage, you can choose to either clean these parts or replace them entirely with new components.

  4. Identifying Worn Parts:

    • Inside the faucet, after removing the cam and packing, you will see springs and seats. The worn seats are primarily responsible for causing the faucet to drip from the spout.
    • These worn seats are recessed into the valve body and can be difficult to remove; however, a number two Phillips screwdriver is ideal for extracting them.

  5. Replacement Parts:

    • When you purchase a repair kit for a single handle faucet, it typically includes a variety of parts. In the kit, the old cam will typically be white, while the new ones included are usually gray.
    • The new cam has an inverted triangle shape similar to the one removed, while other cam shapes may be included for different faucet types.
    • It's important to note that the ball assemblies are not included with the repair kit. You can choose to clean the existing ball assembly if only minor maintenance is required, or replace it if it shows significant wear.

  6. Rebuilding the Faucet:

    • Begin by installing new springs and seats using the reverse order of removal, ensuring they are pressed in securely.
    • Next, lubricate the ball assembly before installation. Pay attention to the slot on one side of the old ball assembly, which should match with the peg on the valve body for proper alignment.

  7. Reassembling the Faucet:

    • After installing the ball assembly, proceed to install the new cam and packing, aligning these parts with the corresponding slot on the valve body.
    • Finally, reinstall the handle cap and tighten it securely using the adjustable wrench. Use a specialized faucet tool to tighten the adjusting ring effectively.

  8. Testing for Leaks:

    • Before reinstalling the handle, turn the water supply back on and check for any leaks. If leakage is detected from either the spout or the base of the handle, further tightening of the adjusting ring may be necessary.
    • If no leaks are observed, proceed to reinstall the handle, ensuring the set screw aligns on the flat part of the ball assembly stem.

Following these comprehensive steps allows for the effective repair of an old faucet, restoring its functionality and extending its lifespan.
