Outdoor taps (hose bibs) take a beating in Ontario weather. Between freezing winters, hot summers, and constant pressure changes, they’re one of the most common sources of leaks, burst pipes, and water damage around the home. The good news: with a little seasonal maintenance, you can keep your outdoor tap working smoothly year‑round.
Problem Overview
Outdoor taps fail for three main reasons:
- Freezing temperatures causing internal cracks
- Worn washers or cartridges
- Loose packing nuts or damaged handles
A few simple checks each season can prevent expensive repairs.
Tools You’ll Need
- Adjustable wrench
- Flat screwdriver
- Garden hose washer (optional)
- Silicone lubricant
- Bucket or towel
Step‑by‑Step Outdoor Tap Maintenance
1. Inspect the Tap for Leaks
Turn the tap on and off. Look for:
- Drips from the spout
- Water seeping around the handle
- Moisture around the wall plate
If you see any leaks, continue to Step 3.
2. Check the Hose Connection
A worn hose washer can cause constant dripping.
- Remove the hose
- Inspect the rubber washer inside the hose end
- Replace if cracked or missing
This solves 50% of outdoor tap drips.
3. Tighten the Packing Nut
If water leaks around the handle:
- Use an adjustable wrench
- Turn the packing nut ¼ turn clockwise
- Test again
This often stops handle leaks instantly.
4. Lubricate the Stem
If the handle feels stiff:
- Turn off the water supply inside
- Remove the handle
- Apply silicone lubricant to the stem
- Reassemble
Smooth operation prevents wear and tear.
5. Winterize the Tap (Critical in Ontario)
Before freezing temperatures arrive:
- Disconnect the hose
- Shut off the interior water valve
- Open the outdoor tap to drain remaining water
- Leave it slightly open over winter
This prevents frozen pipes and costly bursts.
When to Call a Pro
Call a plumber if:
- The tap won’t shut off completely
- You see water leaking inside the house
- The pipe freezes or bursts
- The tap is older than 15 years and repeatedly leaks
