How to Choose a Whole House Water Filtration System

A whole house water filter connects to the main water line that comes into your house and treats all the water. This means that all the water dispensers in your house, such as showers, faucets, baths, kitchen, laundry, and toilets will only dispense treated water. In most cases, the whole house water filter is connected to the main line before it is split off to the water heater. For those customers that want to use filtered water in their yard, there is a problem; the city water lines are often split into a separate house and yard water line in the house foundation slab or on the street. A filtration system like this has a lot of advantages and offers convenience, here are some factors to consider before buying.How to Choose a Whole House Water Filtration System

What Whole House Water Filter Will Suit Your Needs?

The contaminants that are present in your water supply will determine what kind of water filtration system you will need. A house supplied by a municipal water system may have issues, such as chlorine, chloramine, sediment, and minerals that cause hardness. In contrast, water sourced from a private well may have other contaminants, such as iron, iron bacteria, manganese, and sediments. In both cases, the contaminants could range in severity, from minor nuisances to toxicity issues that can harm your health and/or damage plumbing and appliances. Therefore, it’s important to know more about the quality of water your home is receiving and any issues that need to be addressed. A municipal water utility will provide an up to date analysis on request. Private well users will have to get a water analysis carried out by a certified laboratory.

Understanding the Contaminants in Your Water:

Once you have some information about the contaminants that are in your water, you can make an informed decision. The contaminants present and the levels of concentration will help you to determine which kind of water filter system will suit your needs best. There are four main groups of contaminants to consider:

Metals, such as iron, lead, calcium, and magnesium.

Chemicals, such as chlorine, chloramine and fluoride.

Turbidity or cloudiness issues, such as sediment, bacteria, and viruses.

Fecal contaminants, usually: E.Coli.

As an example: if you discovered that you’ve got high concentrations of calcium in your water supply, a water softener could be added to your whole house water filter, to prevent scaling.

Four Key Considerations:

When choosing a whole house water filter, there are four key considerations, they are:

The flow rate: this determines the amount of water that will be available to run you shower and appliances in gallons per minute (GPM). Most homes require at least ten gpm, but usually, fall into the 15 – 50 gpm range.

The filter size: the larger the filter is, the better the water pressure and the longer the service intervals.

The filter life: a good whole house filter may use carbon filter cartridges that last up to 150,000 gallons when filtering municipal water.

The port size: the best port size is 1″ to avoid pressure drops and avoid bottlenecks.

If you’re experiencing problems with the quality of your water, contact your local water professional. There are many different kinds of water treatment systems available to treat a wide variety of water quality issues. Make sure that you chose a water professional who is fully WQA certified and you can be sure that they will meet and possibly even exceed water industry standards.
