Hot Water Dispenser

In today's fast-paced world, we often feel that we don't even have time to wait for water to boil. So, why wait? Install a hot water dispenser for more convenience. Here's how:

Equipment list:
Drill with stainless steel boring bit
Screwdriver
Slip-joint pliers
Adjustable wrench
Torpedo level
Saddle valve, which allows you to tap into a pipe without cutting the pipe
Safety glasses and gloves

For this project, you will need a dedicated GFCI outlet under the sink. If you don't already have one you can easily install it yourself, or you may want to have a licensed electrician install it for you.
The drilling portion of this project is intended for stainless steel sinks. If you have a cast-iron sink, however, you can either install a deck-mount spray faucet, which will free up one hole, or you can drill into the countertop as close to the sink as possible.

Drill a hole in the sink, using the stainless steel boring bit (Figure A). Make sure you have clearance underneath the area you're drilling into. Hold the drill steady, and don't push too hard. Let the drill do most of the work.
Push the dispenser piping through the hole, and fit the assembly into place ( Figure B).

Under the sink, slip the washer and mounting nut over the dispenser's threaded rod (Figure C) and tighten the nut. You may need someone above to hold the unit steady.
Position the mounting bracket on the cabinet in an area near the outlet and dispenser lines. Hold it in place, check to be sure it's level and mark the mounting holes (Figure D).
Attach the bracket with screws and hang the tank on the bracket (Figure E).

Use a saddle valve (Figure F) to connect the unit to the cold water line. First, position the saddle valve on the water line in an area where the dispenser feeder line will reach it and tighten it into place (Figure G). Then begin turning the valve knob clockwise until the needle pierces the water line and the water stops flowing.
Connect the dispenser water feed line using a compression washer and nut (Figure H). Hand-tighten the feed line, making sure the line is square to the valve. Finish tightening the compression nut with a wrench, but be careful not to overtighten.

Connect the water lines from the tank to the dispenser (Figures I and J). The dispenser will have a line from the tank to the dispenser and another to carry overflow back to tank. These will be clearly marked.
Open the saddle valve and check for leaks.
Purge the air by opening the tap until water flows steadily.
Plug the unit in (Figure K).
