Installing a Boiling Water Tap
Boiling water taps are typically monobloc designs, meaning they combine hot, cold, and boiling water functions into one unit. Here's how installation differs from standard faucets:
1. Assess Your Existing Setup
Replacing a monobloc faucet? Straightforward swap-same hole size (1.25–1.5 inches).
Switching from pillar taps (two holes)? You'll need:
A new single-hole sink (or a deck plate to cover old holes).
Plumbing adjustments to connect both hot/cold lines to the monobloc.
2. Prepare the Sink
Single-hole sinks: Directly install the boiling tap.
Three-hole sinks: Use the center hole for the tap and side holes for accessories (soap dispensers, side sprays).
3. Electrical Safety
Boiling water taps require power for the under-sink heater tank:
Dedicated GFCI outlet: Ensure one is within 3 feet of the tank.
No extension cords: Direct wiring only (follow local codes).
Watertight connections: Double-check tubing joints to prevent leaks near electrical components.
4. Additional Connections
Link the heater tank to the cold water line via the provided T-valve.
Secure the tank with brackets (included) under the sink.
Plug in the unit and test for leaks/power issues.
Key Differences vs. Standard Faucet Installation
| Aspect | Standard Faucet | Boiling Water Tap |
|---|---|---|
| Holes Needed | 1–3 (depending on design) | 1 (monobloc) |
| Electrical Work | None | Requires GFCI outlet |
| Plumbing | Hot/cold lines only | Cold line + heater tank hookup |
Common Boiling Tap Installation Mistakes
❌ Ignoring sink compatibility: Trying to force a monobloc into a two-hole sink.
❌ Skipping the GFCI outlet: Risk of electrical hazards.
❌ Overlooking tank placement: Blocking access to under-sink storage.
Pro Tip: Use a voltage tester to confirm power is off before wiring the tank.
