A whole house filter system delivers clean water throughout your entire home so that you can enjoy delicious drinking water at every tap, chlorine-free showers and brighter clothes.
However, this type of water filter requires proper installation that involves plumbing. Sounds scary? It doesn’t have to be! Getting everything up and running is only moderately difficult. And with the right tools and enough time & patience you should be able to do the setup yourself.
Just got an idea for your next DIY project? Great! The following article will provide you with everything you need to know.
The first question that needs to be answered is where you should install your new whole house water filter.
Of course you want to choose a location close to where the main water line enters your home so that you have filtered water at every outlet. The only exception are outside faucets that usually don’t require filtered water – but that’s up to you!
You also want a location that’s easily accessible so that you can service your filtration system – mainly replacing cartridges – without hassle.
Somewhere near the main shut-off valve and upstream of the water heater is probably your best bet. This will increase the heater’s lifespan and the longevity of all your household appliances running on hot water as they do not have to deal with sediment, lime and all that jazz anymore that might be present in your water supply.
If you are on a private well make sure to install the filter system after the pressure tank.

Should you install your new whole house unit before or after the softener (if you have one)?
For municipal supplies before the softener to protect the ion exchange media from chlorine and rule out potential pressure issues.
For well supplies some experts say after the softener to ensure full flow when backwashing. Also, unless you chlorinate your well, your water won’t contain any chlorine that would require removal.
Outside installation is not completely out of question, but placing your whole house filter in your garage or basement is the better option.

The good news is that no matter what model you choose, the fundamental process of installing a whole house water filter system is always the same. If you are handy around the house, the entire setup shouldn’t take more than one afternoon (2 to 4 hours).
Here are some step-by-step instructions:
Before you start, carefully read the manual and make sure that you comply with local plumbing codes. When in doubt about your next step consult the manufacturer.
FYI: During normal operation the bypass valve stays closed. Whenever the system requires servicing, close both regular valves and open the bypass.
If your manual lacks important details make sure to check out some of the resources that can be found online (such as this website). How about the following installation video?
As you have seen, installing a whole home filter DIY-style is not too difficult at all. Just double-check that you have all the necessary tools and components before you start and follow the manufacturer instructions precisely. When in doubt, contact the customer service and search for additional help online. Then you will have your new whole house filtration system set up in no time!
