Dealing with leaky or damaged pipes under your bathroom sink can be a frustrating experience. Whether you’re a DIY enthusiast or a beginner, this comprehensive guide will walk you through the process of fixing pipes under your bathroom sink. From identifying the problem to completing the repair, we’ve got you covered.Before you start, gather the following tools and materials:
- Adjustable wrench
- Pipe wrench
- Plumber’s tape
- Bucket or towel
- Replacement pipes or fittings (if needed)
- Plumber’s putty
- Flashlight
Now, let’s dive into the step-by-step process:
- Turn off the water supply: Locate the shut-off valves under the sink and turn them clockwise to stop the water flow. If there are no individual shut-off valves, you may need to turn off the main water supply.
- Empty the cabinet: Remove all items from under the sink to create working space. Place a bucket or towel beneath the pipes to catch any residual water.
- Identify the problem: Use a flashlight to inspect the pipes. Look for cracks, corrosion, loose connections, or signs of leakage. Common issues include worn-out washers, loose slip nuts, or damaged pipes.
- Disassemble the problematic section: Using your wrenches, carefully loosen and remove the affected pipes. Remember which parts go where, or take pictures for reference during reassembly.
- Clean the connections: Remove any old plumber’s putty or tape from the threads. Clean the surfaces with a cloth to ensure proper sealing when you reassemble.
- Replace or repair damaged components: Depending on what you found during inspection, you may need to replace washers, slip nuts, or entire pipe sections. For small leaks, sometimes just reapplying plumber’s tape is sufficient.
- Reassemble the pipes: Carefully put everything back together, applying new plumber’s tape to threaded connections in a clockwise direction. Hand-tighten first, then use wrenches to secure – but don’t overtighten.
- Test your work: Slowly turn the water back on and check for leaks. Let the water run for a few minutes while monitoring all connections.
For more stubborn problems, here are some additional tips:
- If pipes are corroded, replacement might be better than repair
- For persistent leaks at joints, consider using pipe joint compound instead of tape
- If you’re dealing with old galvanized pipes, they may need professional attention
- Always have spare washers and slip nuts on hand as they often need replacement

- Regularly check under your sink for moisture or small leaks
- Consider installing a leak detection alarm
- Don’t pour harsh chemicals down the drain that could damage pipes
- In cold climates, protect pipes from freezing
When to call a professional plumber:
