Why Install an Instant Hot Water Dispenser?
- Save Time: No more waiting for kettles or microwaves.
- Free Up Counter Space: Compact under-sink design keeps your kitchen clutter-free.
- Energy Efficient: Heats only what you need, reducing power waste.
Tools & Materials You'll Need
- Gather these essentials (most come with the dispenser kit):
- Instant hot water dispenser unit
- Dedicated faucet or dispenser tap
- T-valve fitting (for cold water line)
- Adjustable wrench
- Plumber's tape (Teflon tape)
- Drill & hole saw (if modifying sink/countertop)
- Bucket & towels (for spills)
- Voltage tester (for electrical safety checks)
Step 1: Turn Off Water & Power
- Shut off water supply: Close the cold water valve under your sink.
- Turn off power: Switch off the circuit breaker for safety.
Step 2: Install the Faucet
1. Drill a hole (if needed): Kitchen Faucet Hole Sizes
- Use a 1.25-inch hole saw to create an opening in your sink or countertop.
- Pro tip: Place the faucet near your main sink tap for convenience.
2. Secure the faucet: Insert it into the hole and tighten the mounting nut underneath with an adjustable wrench.
Step 3: Connect to the Water Line
1. Attach the T-valve:
- Wrap plumber's tape around the cold water valve's threads.
- Connect the T-valve to the valve, leaving one port for your main sink faucet and the other for the dispenser.
2. Link the dispenser tubing:
Connect the dispenser's supply line to the T-valve. Avoid kinks in the tubing.
Step 4: Mount the Heater Unit
- Position the unit: Place the dispenser tank under the sink, ideally near an electrical outlet.
- Secure it: Use brackets (if included) or heavy-duty mounting tape to prevent movement.
Step 5: Electrical Setup (If Required)
- Check voltage compatibility: Ensure your outlet matches the dispenser's requirements.
- Plug in safely: Use a GFCI outlet to prevent shocks. Never use an extension cord!
Step 6: Test for Leaks & Activate
- Slowly turn water back on: Open the cold water valve and inspect all connections for drips.
- Power up: Switch on the dispenser and let it heat (check the manual for initial heating time).
- Flush the system: Run water through the faucet for 2-3 minutes to clear air bubbles.
Common Mistakes to Avoid
- Skipping Teflon tape: Causes slow leaks at threaded joints.
- Ignoring electrical codes: GFCI outlets are non-negotiable for safety.
- Over-tightening fittings: Can crack plastic parts, snug is enough!
Maintenance Tips for Longevity
- Descale monthly: Use vinegar or a descaling solution to prevent mineral buildup.
- Replace filters: If your system has one, swap it every 6 months.
- Check for leaks: Inspect connections every 3-6 months.
