Well, in this article we are going to simplify this in easy steps that will be useful when you want to set up an instant hot water dispenser in the kitchen. Having access to near boiling water readily available in the kitchen can really simplify things. The hot water makes cleaning tasks less stressful and also making instant hot beverages like tea and coffee less involving. You wouldn’t think twice to install one after knowing the advantages that come with the hot water dispenser. Here are the steps to guide you in the installation process.

Tools and materials needed

  • Hot water tank system
  • Double compression stop
  • Adjustable wrenches (two)
  • Drill driver
  • High speed drill bit (stainless)
  • Hammer
  • Center punch
  • Tape measure
  • Bullet level
  • Tubing cutter

Step one:

Clear the area under the sink to accommodate the tank. Then turn off the power at the breaker and the water at the water heater. Then mark the area on the sink surface where the tank will be mounted. Make a hole at the center area using a drill and center punch it so that the drill bit does not ramble. You can create the hole using the hole saw available. The hole saw is recommended because it has its own pilot bit attached. Then mount the dispenser in the hole.

Step two:

Select a spot under the sink where the water tank can be mounted vertically and can be accessed when plumbing and connecting electrical lines. Do not hinder the drainage from underside. It should be within 16 inches of the faucet water lines and within 30 inches of a standard grounded outlet. And atleast 3 inches above the bottom of the cabinet. Turn off the cold water feed as you will be working under the sink. You can use a tube cutter and cut the copper tubing to install a compression tee.

Step three:

Connect the tank’s inlet to the compression tee that you had installed the fittings provided. The tubes you are going to cut should not be exact. You should cut them a bit longer to avoid connection difficulties. Hold the tee with one wrench as you make the connection while making the compression nut tight enough with the other trench. The same way you have made this connection, make it on the fitting tank.

Step four:

Fill the tank without first plugging the unit to the electrical outlet. Then turn the water heater you had switched off in the beginning. Open the water stops under the sinks to ensure there are no leaks. For the filter to wash out, you will have to open the cold water faucet at the installed dispenser. Turn off the cold water faucet and then open the hot water faucet for the tank to fill up then water will begin to flow. Now, you can plug in the tank.


These steps are easy to follow provided you have the right tools and materials. You can DIY the plumbing in your house after reading this simple guide to installing a hot water dispenser.
