Best Whole House Water Filter Installation Guide: Expert Setup Instructions

Install Whole House Filters with detailed guide and visual depiction of modern blue water filter system.

Getting clean, filtered water throughout your entire home is a game-changer for your family’s health and comfort.

 

Having installed hundreds of water filtration systems over our decades of experience, we at the Filtered Water Guide team know exactly what it takes to set up a whole-house water filter correctly.

 

While installing a point-of-entry (POE) filtration system might seem straightforward, our extensive experience has shown that it requires specific knowledge and skills that many homeowners don’t possess.

 

Based on our hands-on expertise with advanced water treatment systems, we strongly recommend professional installation for most homeowners.

 

However, if you’re determined to tackle this DIY project, we’ll share our expert insights on the entire installation process.

 

In this comprehensive guide, we’ll walk you through:

By the end of this guide, you’ll have a clear understanding of what it takes to install a whole house water filter system properly and safely.

Choosing the Right Installation Location

Finding the perfect spot for your point-of-entry filter is crucial for optimal performance. Through our extensive installation experience, we’ve found that the best location is typically near where your main water line enters your home.

 

For homes with municipal water supply, you’ll want to position the system as close as possible to where the city water line enters your property.

 

If you’re on well water, we recommend installing the system directly after your well pump on the incoming water line.

Key considerations for placement include:

Whether you need to place the whole house filter before or after a pressure tank

 

One crucial detail we’ve learned from years of installations: your filtration system must be installed before your water line branches off to different areas of your home.

 

Pro tip: We always recommend excluding outdoor spigot lines from the filtration system. This simple step significantly extends the life of your filter media.

Water Softener Placement: A Critical Decision

Should you install your whole house filter before or after your water softener? Our testing and experience show that the answer depends on your specific situation.

 

First, it’s important to note that not every home needs a water softener. We always recommend testing your home’s water to determine if softening is necessary alongside your POE filtration system.

 

Many of the best whole house water filtration systems we’ve installed include water softening capabilities or offer it as an add-on option.
