DIY Guide: Fixing Leaking Faucets and Shower Heads

DIY Faucet Repair Littlestown, PA

Pluming repairs can involve leaking faucets or shower heads. These can be simple repairs, but we often find simple DIY repairs turn into larger problems. In our service of Littlestown, Pennsylvania, we help homeowners fix leaking faucets and shower heads.


A failing shower cartridge, washer, or o-ring can lead to leaks, drips, and costly long-term issues. Need help?


Here’s a step-by-step guide for homeowners dealing with a leaking faucet or shower head:


Step 1: Turn Off the Water Supply

Locate the water shut-off valve under the sink or near the shower. Turn it clockwise to stop the flow of water.


To prevent water damage in case of a leak, it's important to know the location of the water shut-off valve in your home. The valve is typically found under the sink or near the shower. To stop the flow of water, turn the valve clockwise. You can also locate the main water valve, typically found in the basement.


Step 2: Plug the Sink or Shower Drain

When conducting plumbing repair, it is essential to take precautions to prevent small parts from falling down the drain. A simple yet effective method is to place a stopper or a cloth in the drain before beginning the repair work. This will help in safeguarding against any accidental loss of components that could further complicate the repair process.


Step 3: Disassemble the Faucet or Shower Head

Carefully remove the handle and other components. For faucets, use a wrench to loosen the screw. Be sure not to strip the securing screw and make sure you keep all your components in a safe area like a bin or bag.


Step 4: Inspect the Faucet Parts

Check for worn-out washers, O-rings, or seals. These are often the cause of leaks. Here's what to look for:


  1. Visible Cracks or Tears: Inspect the rubber components for any cracks, tears, or signs of deterioration.

  2. Flattened or Misshapen Parts: Washers and O-rings that have lost their shape or appear flattened may no longer provide a proper seal.

  3. Hardening or Brittleness: If the material feels hard or brittle instead of flexible, it’s likely worn out.

  4. Water Stains or Corrosion: Look for signs of water stains, rust, or corrosion around the components, which can indicate leakage points.


Step 5: Replace Damaged Faucet Parts

Take the old parts to a hardware store to find exact replacements. Install the new parts in the reverse order of disassembly.


HELPFUL TIP: When taking apart your facet, record a video or take pictures so you can follow these exact same steps in reverse for proper assembly.


Step 6: Reassemble Your Facuet and Test

Put the faucet or shower head back together, turn the water supply back on, and test for leaks. If the leak persists, it might be time to call us at 1-717-640-6442.


To provide an example, one of our homeowner in Sykesville, Maryland had a leaking shower head and replaced the inner cartridge that turns left or right for water temperature or on/off. He purchased the exact same model and installed it correct, but he still had a leak.


After inspecting the installation, we discovered the replacement cartridge he purchased from Home Depot was faulty. He installed a working cartridge and instructed him to return the faulty item.
