Replacing a tap spout typically involves turning off the water supply, locating and removing the retaining screw or collar, detaching the old spout, preparing the new spout with lubricant, installing it, and turning the water back on.
Replacing a tap spout can be a straightforward task, often needed if the old one is damaged, leaking, or simply isn't swiveling smoothly.
Why Replace Your Tap Spout?
Replacing your tap spout can address several issues:
- Leaks: Worn-out O-rings or seals are a common cause of leaks at the base of the spout.
- Poor Swiveling: A spout that doesn't turn easily can be frustrating. Lubrication or new O-rings can help.
- Damage: Physical damage or corrosion can necessitate a replacement.
- Aesthetics: You might want to update the look of your tap.
Tools You May Need
Gathering the right tools beforehand makes the job easier:
- Adjustable spanner or wrench
- Allen key set (imperial and metric)
- Flathead screwdriver
- Crosshead screwdriver
- Penetrating oil (optional, for seized parts)
- Rag or towel
- Bucket or container
- Replacement O-rings (if not included with the new spout)
- Food-grade silicone-based grease
Step-by-Step Guide to Replacing a Tap Spout
Follow these steps carefully to replace your tap spout:
- Turn Off the Water Supply: This is the most crucial first step. Locate the isolation valves under the sink or the main water shut-off for your property. Turn the valves clockwise to shut off the hot and cold water supply to the tap.
- Drain the Tap: Open the tap fully to drain any residual water from the pipes. Place a bucket or towel under the tap to catch drips.
- Identify the Retaining Mechanism: Examine the base of the spout where it meets the tap body. Look for:
- A small grub screw (often concealed at the back or side) which requires an Allen key.
- A screw hidden under a decorative cap (use a small flathead screwdriver to gently pry off the cap).
- A collar or retaining ring that unscrews.
- Sometimes, the spout simply pulls upwards after removing a handle/cartridge above it (less common for standard swivel spouts).
- Loosen and Remove the Retaining Mechanism: Use the appropriate tool (Allen key, screwdriver, or spanner) to loosen and remove the screw or unscrew the collar. Keep track of this small part!
- Remove the Old Spout: Gently pull or twist the old spout upwards and away from the tap body. If it's stubborn, try wiggling it slightly. Do not force it, as you could damage the tap body. If necessary, a little penetrating oil might help break the seal if it's seized.
- Inspect and Clean the Base: Look at the tap body where the spout was seated. You'll likely see one or two rubber O-rings. Inspect these for wear, cracks, or damage. Clean the area thoroughly, removing any mineral deposits or old grease.
- Prepare the New Spout:
- Check if your new spout came with new O-rings. If so, remove the old O-rings from the tap body (if they stayed there) and place the new O-rings onto the grooves at the base of the new spout.
- Apply Food-Grade Silicone-Based Grease: As highlighted in references like the FMM 11 - Changing Spout video, applying food-grade silicone-based grease is essential for smooth operation, especially if the spout isn't swiveling smoothly. Apply a generous amount of this grease to the O-rings and the base of the new spout that will sit inside the tap body. This ensures a good seal and allows the spout to swivel easily.
- Install the New Spout: Align the new spout correctly with the opening on the tap body. Gently push it down into place. You should feel the O-rings seating properly.
- Re-secure the Retaining Mechanism: Reinsert the screw or screw the collar back into place. Tighten it just enough to hold the spout firmly without overtightening, which could pinch the O-rings or damage the tap.
- Turn Water Supply Back On: Slowly open the isolation valves or the main water supply valve.
- Check for Leaks and Operation: Turn the tap on and off a few times. Check around the base of the spout for any leaks. Also, test that the spout swivels smoothly. If there are minor drips, the O-rings might need a moment to seat properly, or the retaining mechanism might need a slight adjustment. If leaks persist, you might need to disassemble and check the O-rings and seating.
Maintenance Tips
- Regular Cleaning: Keep the base of the spout clean to prevent mineral build-up that can hinder swiveling.
- Lubrication: If your swivel spout becomes stiff over time, you might be able to remove just the spout (following the steps above) and re-apply food-grade silicone grease to the O-rings without needing a full replacement.
- Correct Grease: Always use food-grade silicone-based grease for tap components that come into contact with drinking water. Other lubricants can degrade rubber or be unsafe.
Replacing a tap spout is a manageable DIY project that can save you the cost of a plumber and extend the life of your tap.
