This comprehensive guide from Asturias Bathrooms will walk you through every step of the process. From gathering the right tools to disconnecting the old tap and fitting the new one, we will cover everything you need to know. By following these instructions, you can successfully install a new bathroom tap and enjoy the rewarding feeling of a job well done.
Preparation and Tools
Before you begin, it is crucial to gather all the necessary tools and parts. Having everything ready will make the installation process much smoother and prevent any interruptions.
Parts and Tools You Will Need:
- New basin mixer tap (including threaded bar, tap tails, and sealing washer)
- New basin waste (if included or purchased separately)
- Basin wrench (also known as a tap spanner) for tight spaces
- Adjustable wrench or pliers
- Bucket and old towels
- Plumber's tape (PTFE tape)
- Screwdriver
- Silicone sealant (optional, for extra protection)
Step-by-Step Installation Guide
Follow these steps carefully to ensure a secure, leak-free installation of your new basin tap.
Step 1: Shutting Off the Water Supply
First, you must turn off the water supply to the basin.
- Locate the isolation valves under the basin. These are small valves on the hot and cold water pipes. Turn them clockwise to shut off the water flow.
- If you do not have isolation valves, you will need to turn off your home's main water supply at the stopcock.
- Once the water is off, open the old tap to drain any remaining water from the pipes. Place a bucket and towels underneath to catch any drips.
Step 2: Disconnecting the Old Tap
Now it is time to remove your existing tap.
- Use a basin wrench to loosen and remove the nut that secures the old tap to the underside of the basin.
- With an adjustable wrench, disconnect the flexible tap tails from the hot and cold water supply pipes.
- Once disconnected, lift the old bathroom tap out from the top of the basin.
Step 3: Removing the Old Waste (If Applicable)
If your new tap includes a waste, you will need to remove the old one.
- Place a bucket under the U-bend (waste trap) and unscrew it to remove it.
- Use a wrench to loosen the backnut holding the old waste in place.
- Push the old waste up and out of the basin.
- Clean the area around the drain hole thoroughly, removing any old sealant.
- The Bristan Apelo Eco Start Small Basin Mixer with Waste in Chrome is an excellent choice as it is supplied with a colour-matching basin waste for a coordinated look.
Step 4: Installing the New Mixer Tap
With the old tap removed, you can now fit your new basin mixer.
- Attach Parts: Screw the threaded bar into the base of the new tap by hand. Then, hand-tighten the flexible tap tails. Be careful not to overtighten, as this could damage the threads.
- Position the Tap: Place the rubber seal over the tap tails to sit at the base of the tap. Feed the tap tails through the hole in the basin and position the tap so it sits straight.
- Secure from Below: From underneath the basin, slide the rubber and then the metal clamp washers over the threaded bar. Screw on the fixing nut by hand. Check the tap's alignment from above one last time before using a basin wrench to tighten the nut fully.
Step 5: Installing the Pop-Up Waste
Many basin mixer taps available on Asturias Bathrooms are supplied with a matching waste. If your tap came with a new waste, install it now.
- Place one of the rubber washers over the main body of the waste. Some installers add a small amount of silicone sealant here for an extra-secure seal.
- Insert the waste into the drain hole from above.
-
From underneath, place the second rubber washer onto the waste's thread and screw on the backnut. Hand-tighten first, then use a wrench for a final turn. Do not overtighten.
Some taps, like the highly-rated Scudo Core Gunmetal Tall Mono Basin Mixer, do not include a waste. Customers love its stylish design and quality, with reviews stating it is a "great price and delivered on time" and praising its "excellent service with great quality products." If you need to install a waste separately, please refer to our dedicated guide on How to Install a Basin Waste.
Step 6: Reconnect the Plumbing
Now, connect your new tap to the water supply.
- Attach the flexible tap tails to the hot and cold water pipes. Hand-tighten the connections, then use a wrench for a gentle final turn.
- Reconnect the waste trap to the new basin waste outlet, ensuring all connections are snug.
Step 7: Testing for Leaks
Testing your new tap for leaks is the final, crucial step.
- Slowly turn the water supply back on at the isolation valves or main stopcock.
- Run the new tap and carefully inspect all connections - at the tap base, the supply lines, and the waste - for any signs of leaks.
- Fill the basin and then release the water to test the pop-up waste and ensure the drain is watertight.
Troubleshooting
Even with careful installation, you might encounter a minor issue. Here is how to address common problems.
Leaks from the Base of the Tap:
If you see water dripping from the base of the tap, the fixing nut underneath may not be tight enough. Use your basin wrench to tighten it a little more. Ensure the rubber seal is properly seated between the tap and the basin surface.
Dripping from the Tap Spout:
A brand-new tap should not drip. However, if it does, it could be due to an issue with the internal cartridge. Most modern taps use Ceramic Disc Valves, which are highly durable and reliable. These valves operate with a simple quarter-turn and create a perfect watertight seal. If a new tap drips, it may be a manufacturing fault, and you should contact the supplier.
