Water Heater Under Sink Installation

Installing a water heater under your sink is a great way to save space and get hot water fast. Under-sink water heaters are typically smaller than traditional water heaters, so they can fit in tight spaces. They also heat water quickly, so you don't have to wait long for hot water. In this article, we will provide you with step-by-step instructions on how to install an under-sink water heater.

Step 1: Gather Your Materials

Before you begin, you will need to gather the following materials:

Under-sink water heater
Water supply lines
Drain line
Electrical wire
Screwdriver
Wrench
Pliers

Step 2: Choose a Location

The first step is to choose a location for your under-sink water heater. The best location is under a sink that is not used frequently, such as a utility sink or a bathroom sink. Make sure that the location is well-ventilated and that there is enough space to work.

Step 3: Install the Water Supply Lines

Once you have chosen a location, you need to install the water supply lines. The water supply lines should be made of copper or PEX tubing. Connect the water supply lines to the water heater using compression fittings.

Step 4: Install the Drain Line

The next step is to install the drain line. The drain line should be made of PVC pipe. Connect the drain line to the water heater using a drain trap.

Step 5: Install the Electrical Wire

The next step is to install the electrical wire. The electrical wire should be made of 12-gauge wire. Connect the electrical wire to the water heater using a wire nut.

Step 6: Turn On the Water and Electricity

Once you have installed all of the connections, you can turn on the water and electricity. Turn on the water supply valves and then plug in the water heater. The water heater will start to heat the water.

Step 7: Check for Leaks

Once the water heater has been running for a few minutes, check for leaks. Look for leaks at all of the connections. If you find any leaks, tighten the connections.
