To stop your tap from leaking from its base, you will typically need to tighten a small grub screw or a collar at the base of the spout, or replace worn seals beneath it. These are common and often straightforward fixes that can prevent further water damage and wasted water.
Understanding Leaks from the Tap Base
A leak at the base of your tap usually indicates an issue with how the spout connects to the main tap body. This connection point is designed to be watertight, and when seals wear out or fastening components loosen, water can escape. Addressing these issues promptly is key to maintaining your tap's longevity and preventing potential water damage to your sink area or cabinetry.
Common Causes and Solutions for Base Leaks
The solution depends on the specific design of your tap and the underlying cause of the leak.
1. Tightening a Grub Screw (Most Common Fix)
Many taps, especially those with a swivel spout, feature a small grub screw located near the base of the spout. This screw secures the spout to the tap body, and when it loosens over time, it can cause a leak.
- Tools Needed: An Allen key or a small flathead screwdriver, depending on the screw type.
- Steps:
- Turn off the water supply to your tap. This is crucial for any tap repair.
- Locate the grub screw. It's often found at the back or side of the spout, close to where it meets the main tap body. You might need to gently rotate the spout to find it.
- Tighten the screw. Insert the appropriate tool and turn the grub screw clockwise, just slightly, until it feels snug. Avoid overtightening, which could strip the screw or damage the tap.
- Test the tap. Turn the water supply back on and check for any remaining leaks.
2. Adjusting a Collared Spout
Some taps utilize a decorative or functional collar at the base of the spout to hold it in place. If your tap has this design, a loose collar could be the source of the leak.
- Tools Needed: Your hands, possibly a strap wrench if the collar is stiff.
- Steps:
- Turn off the water supply.
- Twist the collar. Gently try to twist the collar clockwise to tighten it. It should feel firm when properly secured.
- Test the tap. Restore water supply and check for leaks.
3. Replacing Worn or Damaged Seals
If tightening the grub screw or collar doesn't resolve the leak, the issue is likely due to worn or damaged internal seals (often O-rings) at the base of the spout. These seals create a watertight barrier, and they can degrade over time.
- Tools Needed: Allen key/screwdriver, adjustable wrench (optional, for tap body if needed), new O-rings or seals (e.g., faucet O-rings), plumber's grease, towel or cloth.
- Steps:
- Turn off the water supply to the tap.
- Remove the spout. If there's a grub screw, remove it completely. If there's a collar, unscrew or lift it off. Then, carefully lift the spout straight up and off the tap body.
- Inspect the seals. You will typically see one or more rubber O-rings or flat washers around the base of the tap body or inside the spout where it connects. Note their position and condition.
- Remove old seals. Use a small screwdriver or pick to carefully pry out the old, worn seals.
- Clean the area. Wipe down the base of the tap body and the inside of the spout to remove any debris or mineral buildup.
- Install new seals. Apply a thin layer of plumber's grease to the new O-rings or seals before sliding them into their correct positions. This helps them seat properly and last longer.
- Reassemble the tap. Carefully place the spout back onto the tap body, ensuring it seats correctly. Reinstall the grub screw or collar.
- Test the tap. Turn the water supply back on slowly and check thoroughly for any leaks.
Essential Tools for the Job
Having the right tools on hand can make tap repair much smoother:
- Allen Key Set: Essential for grub screws.
- Small Flathead Screwdriver: For grub screws or prying out old seals.
- Adjustable Wrench: For tightening nuts or connections, though less common for a base leak.
- Plumber's Grease: To lubricate new O-rings.
- Replacement O-rings/Seals: Ensure they match your tap's make and model if possible, or bring the old ones to a hardware store.
- Towel or Cloth: For catching drips and cleaning.
Quick Troubleshooting Guide for Base Leaks
| Issue Type | Potential Cause | Recommended Fix |
|---|---|---|
| Minor Drip | Loose grub screw or collar | Tighten grub screw or twist collar clockwise |
| Constant Leak | Worn or damaged O-rings/seals | Replace O-rings/seals at the base of the spout |
| Persistent Leak | Damaged tap body or internal damage | Consult a professional plumber |
When to Call a Professional Plumber
If you have followed these steps and the tap continues to leak from the base, or if you're uncomfortable attempting the repair yourself, it's always best to contact a qualified plumber. They can diagnose more complex issues, such as internal component damage, issues with the tap's mounting, or problems with the water supply lines, ensuring a lasting solution and preventing further water damage to your home.
