The best way to ensure you have fresh drinking water in your home is to install a water filtration system. A water filtration system allows you to pull water from rivers, creeks, wells, and lakes to drink and use to make meals. If you don't have the money to spend on installing and operating a large filtration system in your home, you can put in a dedicated water filtration line under your kitchen sink to use for drinking water. You should have at least a little experience working with plumbing before tackling this project. Here is how to install a water filtration system at your kitchen sink.
Step One: Install a "T" Connection
Shut off the cold water supply going to the kitchen faucet. If you don't have a shutoff valve under the sink, turn the main valve off that supplies water to the entire house, or turn off the water pump if using well or river water – make sure to drain the water under pressure in the line before you start doing any other work.
Cut the pipe going from the shutoff valve to the cold water faucet stem, and put in a "T" connection. If you don't have a shutoff valve under the sink, place one on the water line before you install the "T" connection – this way you won't have to shut off the water going to the entire house when you have to change water filters on the system.
Reconnect the pipe going to the kitchen faucet stem.
Step Two: Install Dedicated Faucet
Mount a dedicate faucet for the water filtration system into the sprayer hole on the kitchen sink. You'll have to drill a new hole for the faucet if your sink doesn't have a pre-existing hole for the sprayer.
Step Three: Install Water Filtration Components
Place the bracket to hold the water filter container on the back wall under the sink.
Place a reducer on the "T" connection going to the water filtration system. Attach the plastic hose from the filtration system to the reducer, and then connect it to the side of the plastic container holding the filters.
Connect the outlet spigot on the other side of the container to the stem on the dedicated faucet with a piece of plastic hose.
Screw the filters into the bottom of the container. Place the top on the container.
Step Four: Test System
Turn on the cold water going to the kitchen sink and check for leaks. Open the dedicated faucet for the new water filtration system to make sure you have water, and pour yourself a glass of water to check how it tastes.
