How to Install a Whole House Water Filtration System? 

If you live in a home with well water, you may be interested in installing a whole-house water filtration system to reduce the number of contaminants in your drinking water. These systems remove a variety of impurities, including bacteria, sediment, chlorine, and other chemicals that could affect the quality of your water.

Installing a whole-house water filter can be an easy DIY project with a little know-how and the right tools. However, if you have never installed a whole-house water filtration system before, it may be best to hire a plumber. 

Before you begin the installation, determine where you want to install your system. This will help you avoid running into problems later. If you have a specific location in mind, take measurements and make note of the size of your plumbing pipes to ensure you get everything you need. 

Choose a spot where you can reach the filters easily and safely. Keep in mind that you’ll need to change the filters from time to time, so choosing a spot that is accessible and free of obstacles will make it easier. 

Cut a section of pipe about 3 feet long that’s large enough to fit two filter units. If you’re installing a pre-filter and carbon filter, install copper tees on both sides of the section to make it easier to attach the filters. 

Next, mount a sediment pre-filter to the wall with mounting brackets and fittings. This unit captures dirt and rust particles, which can contribute to hard water buildup and clogged drains. Once the sediment pre-filter is in place, you can attach the carbon filter to the wall. 

Connect the plumbing pipes to the filter and the piping to your main water line. Check the instructions for the model you’re installing to determine how to connect the pipes and how to install a shut-off valve. 

Then, attach a filter mounting bracket to the floor or wall joist. This will be the location where you’ll secure the filter cartridges to prevent them from being pulled out during maintenance. 

Depending on your water supply, you may need to replace your filter unit every 6 months or so. When you do, turn off the water and drain all lines. Then, unscrew the filtration tank and pull out the old filter cartridges. Put a new one in and screw the tank back into place. 

You can use a soldering gun to connect the plumbing pipes. Before you do, apply thread seal tape to the fittings, then thread them into the filter valve as instructed in the manual. 

Soldering will degrade plastic and the internal parts of the filter, so you don’t want to overdo it. If you’re using a torch to solder, apply a heat protectant to prevent the metal from getting too hot. 

If you’re working with copper pipes, you need to locate a ground wire attached to your water line. If you don’t have a ground wire, you can buy a ground clamp and add it to your home’s electrical panel.
