Installing a diverter tap involves replacing your old tap with a new one that can redirect water flow to a secondary outlet, such as a shower head, sprayer, or filter system. While the exact process varies depending on the type of tap (kitchen, bath, shower) and plumbing, the fundamental steps involve disconnecting the old fixture, preparing the mounting surface, securing the new tap, and making the necessary water line connections.
General Steps for Tap Installation
Here are the common stages when installing or replacing a tap that may include a diverter function:
1. Prepare the Area
- Turn off the Water Supply: Locate the isolation valves under the sink or the main water shut-off for your home and turn off both hot and cold water supplies.
- Drain the Lines: Open the existing tap to drain any residual water from the pipes.
- Clear the Workspace: Remove items from under the sink or around the bath/shower area to provide clear access.
2. Remove the Old Tap
- Disconnect Water Lines: Use a wrench to loosen and disconnect the hot and cold water supply lines from the underside of the old tap. Have a bucket or cloth ready to catch any drips.
- Remove Mounting Hardware: Locate the nuts or screws securing the old tap to the sink, countertop, bath, or wall. Use the appropriate tool (basin wrench, screwdriver) to loosen and remove them.
- Lift Out the Old Tap: Carefully lift the old tap from its mounting hole.
3. Install the New Diverter Tap
- Prepare the New Tap: Read the manufacturer's instructions for your specific tap. This may involve attaching water supply lines to the tap body or installing gaskets.
- Position the Tap: Place the new diverter tap onto the mounting surface, ensuring any gaskets or seals are correctly seated. Feed the water supply lines and mounting hardware through the hole.
- Secure the Tap: From underneath, attach the mounting hardware (washers, nuts) and tighten them to secure the tap firmly. Be careful not to over-tighten, which could damage the surface.
4. Connect Water Supply Lines
-
Connect Supply Lines: Attach the hot and cold water supply lines from the tap to the corresponding hot and cold water pipes. Hand-tighten first, then use a wrench for a final snug turn. Avoid overtightening.
-
Connect Diverter Outlet: If the diverter tap has a separate outlet (e.g., for a sprayer hose or filter connection), connect the relevant hose or pipe to this outlet following the manufacturer's instructions.
-
Example of Specific Connections: Plumbing connections can vary. For instance, when connecting specific units that utilize a diverter or tee fitting from a source line, like plumbing a Reverse Osmosis Deionization (RODI) unit into a compression fitting, you might need to remove a compression nut and slide it onto the source waterline before making the connection, as described in some installations.
5. Test the Tap
- Restore Water Supply: Slowly turn the hot and cold water isolation valves back on. Check for any leaks immediately at all connection points.
- Check Diverter Function: Operate the tap and test the diverter mechanism to ensure water flows correctly from both the main outlet and the secondary outlet (e.g., spout and shower head, or tap and sprayer). Check for leaks again when the diverter is engaged.
6. Final Checks
- Inspect All Connections: Visually inspect all connections for any signs of leaks. Tighten slightly if necessary, but avoid excessive force.
- Clean Up: Clear away tools and cleaning materials.
Installing a diverter tap requires attention to detail and ensuring all connections are secure to prevent leaks. If you are uncomfortable with plumbing work, consider hiring a qualified plumber.
