Simple DIY Method to Repair a Single-Lever Faucet

The Hidden Flaw of Modern Faucets

Today’s single-lever faucets often break in ways that make simple gasket replacement impossible. Their design leaves no room for detachable parts, turning even minor repairs into costly replacements. Yet, skilled DIY enthusiasts have discovered a way to restore a faucet’s function without buying a new one.

What You’ll Need

Prepare the following tools and materials:

  • Flat and Phillips screwdrivers
  • Hex key or compatible driver for fasteners
  • Adjustable wrench
  • Small container for cleaning parts
  • Table vinegar or citric acid
  • Clean water
  • Silicone grease

Step-by-Step Guide

1. Turn off the water

Before taking the faucet apart, shut off the water supply — either the main valve or the one for that specific line.

2. Remove the handle

Start by taking out the small plastic cap, then loosen the fixing screw with a hex key. Detach the handle along with its housing.

3. Dismantle the inside

The faucet’s core contains several plastic components secured by clips. Remove the three elastic seals and separate the body into individual parts.

4. Clean off mineral deposits

Soak the components in a mixture of water and vinegar (or citric acid). After a few hours, mineral and salt buildup will dissolve. Rinse the cleaned parts thoroughly with water.

5. Lubricate and reassemble

Put everything back together using silicone grease on the internal surfaces. This helps restore smooth lever motion and ensures watertight connections.

6. Reinstall and test

Mount the faucet back in place, tighten the fasteners, and reopen the water supply. Check its operation — the faucet should work smoothly again, with no leaks or stiffness.

Why This Works

This DIY approach saves money and gives an old faucet a second life. Careful disassembly and thorough cleaning are key to success. Silicone grease not only prevents jamming but also extends the life of the seals.

A simple, time-tested trick: with occasional maintenance every few years, your faucet can keep working flawlessly for many more.
