Whole house water filters and water softeners are typically not offered as a single system. If you want to use both in your house, you’re going to have to purchase them separately, install them, and hook them up to each other.
This is not as difficult as it seems, as long as you take the time to prepare with the right materials and figure out a suitable installation spot.
No idea how to do that? Enter our guide on how to install a whole house water filter and softener combo!
These are the steps on how to install a whole house water filter and softener combo:
Additional steps for salt-based water softeners:
When choosing a whole house water filter and softener combo, make sure that the warranty allows you to perform the installation yourself. With some products on the market, you may be required to use the services of a professional, otherwise you risk voiding the warranty.
You should install your filter-softener combo in a place where it can process the entire water supply of the home. This means placing it as close as possible to the entry point. If you also want to cover external faucets, this can get a bit trickier and you might have to set up the filter further back along the line.
Another important consideration is to make sure that you have easy access to the location of your choice. Installing a whole house filter and softener is not the end of your related work – you’ll have to eventually come back to it to replace filter cartridges and refill salt, and you don’t want to make that process unnecessarily messy.
Here’s a list of parts and tools that should cover the installation of most whole house water filters and softeners on the market.
Before beginning, make sure you’re familiar with the product’s manual. The following guide should cover the installation of most models on the market, but there may be individual differences that should not be ignored.
So, how do you install a whole house water filter and softener combo?
Once you’re done with the basic installation, you’re almost ready to turn everything on. Before doing that, you must fill the water softener with salt and check for leaks.
One important decision you should make before starting the installation process is the order of hooking up your whole house water filter and water softener.
There is no one-size-fits-all solution here as this will depend on your water supply.
Your source of household water will be a major factor in determining the appropriate installation order. If you’re using well water, you will likely have more dirt and other particles in your supply, requiring a filter before softening.
Dirt, chlorine, and iron can negatively affect the operation of a water softener, too. Depending on your specific model, they might render it entirely useless in a short time.
Thus, if your water supply contains large amounts of sediment, chlorine, or iron, you should install your whole house water filter first or add a pre-filter before the water softener.
High amounts of limescale can hurt a filter’s performance. If this is something that concerns you, consider installing your water softener before the water filter.
Also check the water flow rate supported by your whole house water filter. In order for your water softener to function correctly, it’s going to need a minimum level of flow rate. Otherwise, the softening medium will not be activated properly and the device will function below its capacity.
With that in mind, you should connect your water softener before the whole house water filter if the filter is going to be a bottleneck in terms of flow.
The opposite may also be true. Your whole house water filter might require a minimum flow rate to do its job properly. In that case, verify that the water softener supports that rate at its output.
This means that you should always purchase these devices together. Remember: You need to account for the output flow rate of each one and the input requirements of the other. Some pairs of whole house filters and softeners will be incompatible no matter what you do.
By the way, this also applies to backwashing flow rates!
