Your kitchen sink is one of the biggest users of water in your residence. Over the course of a year, your faucet releases about 10,000 gallons of water. Choosing an eco-friendly kitchen faucet and installation can help to conserve water and lower your utility costs by an average of $170 dollars annually. The actual process is not much different than a traditional installation, but will make a big difference in water usage. This is a moderately challenging task and should be completed in about a day.

Materials Needed

  • Eco-friendly kitchen faucet

  • Low-flow aerator

  • Bucket

  • Shutoff valves (optional)

  • Stainless steel supply tubes

  • Screwdriver

  • Hammer

  • Basin wrench

  • Pipe wrenches

  • Open-end wrenches

  • Hacksaw

  • P-trap




Step 1. Select the Faucet

This will be the most important step in completing an eco-friendly kitchen faucet installation. There are several different options. Consider purchasing one that already has an aerator installed. If this is present, there will be flow rates imprinted on the side. Most distributors will have markings on their faucets that are eco-friendly such as an EnergyStar or WaterSense certification. To achieve a WaterSense certification, there needs to be a 30 percent reduction in water.

Step 2. Turning off the Water Supply

Once you have selected your faucet you are ready to install it. It is imperative that the water supply is shut off. Place the bucket under the sink directly below the P-trap in order to catch any water left in the pipes.

Step 3. Remove the Drain Lines

Drain lines that are located under the sink, can get in the way over the course of installation. If you can reach everywhere without removing these then you can skip this step. The drain lines can be removed with a pipe wrench. It is a good idea to take a picture of your drain lines under the sink prior to beginning. This will help you to remember how to reassemble later.

Step 4. Check for Shutoff Valves


Shutoff valves will be very handy in the future. When you are looking at the plumbing under the sink, check to see if there are shutoff valves. If not, install these with the new faucet. To do this, cut the water supply lines using the hacksaw and then attach the shutoff valves.

Step 5. Unmount the Sink

It is actually not difficult to unmount the sink. Simply take the basin wrench and loosen the lock nuts behind the sink. Pull up on the sink and clean in the underneath area.

Step 6. Place Flange over Plumbing Opening

Once the sink has been unmounted, the flange is placed over the opening. This should only be tightened with your fingers at this point.

Step 7. Inserting the Faucet


If you have an existing faucet, you will need to first remove that. Check the manufacturer’s instructions and follow those for the primary installation. You can expect to pay about $200 dollars for a high-quality faucet. There are not significant differences in quality past this price point.

Step 8. Tighten the Faucet and Flange Nuts

Once the faucet has been put in place, the nut under the sink must be tightened in the right direction. Place it through the flange and sink holes, then put the washer and faucet nut on. To put the flange nut on, use an open-end wrench and tighten it securely.

Step 9. Cut the supply lines

Locate the compression nuts on the valves and mark the supply lines directly about this location. Cut the supply lines and then choose the new tubing and attach it to the supply lines with the accompanying materials.

Step 10. Install an Aerator

If the faucet does not already come with an aerator, you will need to install one. For the kitchen sink, you will want an aerator with a flow of 2 gallons per minute. Use the white pipe tape around the thread. Place the rubber washer and aerator inside the faucet. Tighten the aerator by hand and check for leaks. If there are leaks, gently use a set of pliers to firmly tighten, but not over tighten the aerator.

Congratulations! You have now successfully installed your own eco-friendly kitchen faucet. This is a time-consuming project with several parts, but will ensure that you are now eco-friendly and ready to do more with less water!
