What is a Whole-House Water Filter?

A whole-house water filter is a type of water filtration system that is installed on the main water line entering your home. Whole-house water filters remove contaminants from all the water coming into your home, so every time you turn on the faucet or use the shower, you’re getting clean, filtered water. These contaminants include things like chlorine, iron, sulfur, dirt, debris and other things.

While there are many different types and brands of whole-house water filters available, they all work to do the same thing: remove impurities from your water supply. By filtering out contaminants at the point of entry, whole-house water filters provide clean, safe water for your entire home. This filtration system stops the contaminants much earlier in your pipes than a filter attached to a specific faucet will.  By doing this, you are able to make sure all of your home’s water sources are clean – not just one.

What are the Causes for a Water Filter to Keep Clogging?

One of the main causes of water filter clogs is simply not changing the filter often enough. Over time, the filter becomes filled with contaminants and debris, which can eventually lead to a clog. Depending on the type of water filter you have, it should be changed every few months to ensure that it’s working properly. 

Sometimes, the filter is simply too fine.  Since less can get through the filter, it is likely to clog more quickly.

How do you change the filter on your whole house water filter?

Changing the filter on your water filter is actually pretty easy to do! Most water filters will have instructions on how to change the filter, but if you do not have those, don’t worry.  Here are some easy steps to change the whole house water filter in your home:

  1. Turn off the main line’s water feed.  This will stop water from continuing to try to run through the filter while you are changing it.
  2. Take out the casing and the large o-ring.  You will want to clean the o-ring off first.  If it is severely dirty or no longer functional, you can always pick up a new one. 
  3. Take out the clogged filter and dispose of it properly.  
  4. Clean the casing with warm water, kitchen soap, and either a cloth or sponge.
  5. Add silicone grease to the o-ring to help it sit in the casing properly and then put it back in its normal spot.
  6. Add the new water filter cartridge to the casing.  Make sure it is inserted correctly and is the correct filter.
  7. Close the cap of the casing, put it back where it belongs, and turn the water back on.
  8. Regularly check the water filter to make sure that it is not clogged again.
