How to Change Your House Water Filters 7 Steps!

Do you want to learn how to easily change your whole house, cottage or cabin water filter? You know, it can’t be all that difficult and it seems like a waste of your time to try to arrange a plumber come out to do it for you! And what about the cost to do such a simple job? 

My Easy 7 Step Process on How to Change Your House Water Filters is for the cottage, cabin or homeowner, who wants to change their own water filters to save the hassle and expense of having a plumber do it for them. In this blog, you’ll learn when you need to replace the filter, as well as what you need to do to prepare and how to do the work yourself. 

This is what you’ll need before you start:

  • Replacement filter – if you’re not sure, this YouTube video of mine will help.
  • Correct size Filter housing Wrench or Universal Wrench Bucket to catch the water, and some clean rags.
  • Plumber’s silicone grease.

You would replace a whole house water filter cartridge whenever the water flow slows down in your home, cottage or cabin or after one year of use, whichever happens first. You don't want bacteria growing inside that filter! Prepare a bucket with clean soapy water ahead of time because once you open the filter housing you won't have access to water until you're finished.

  1. Turn your water supply off. You probably have a shutoff on the supply line located before the filter. If not, go to the hydro panel and turn the pump off.
  2. Release any water pressure in the water lines before you unscrew the water filter housing. You need to turn a faucet on inside the house to release the pressure and let the water run until it stops or at least slows to a trickle. Then shut off the water after the filter housing to keep the water from the house from draining back through the open filter housing.

  3. Place a bucket under the filter housing. Unscrew the housing and take it off being careful to minimize spilling the water from inside the housing.
  4. Remove the old filter and clean the inside of the housing with soapy water and towels to remove any built-up debris. Check to make sure that there are no old rubber gaskets inside the filter housing.
  5. Put some clear plumbers silicone grease on the O-ring, which will help preserve the O-ring, make it seal better and make it easier to remove the next time. Unwrap and slide the new filter into the housing and screw it back in place, slightly more than hand tight, about 1/8 to ¼ turn.
  6. Turn the faucet off that you had running to release pressure. Turn the main water supply back on, partially. Check for leaks around the cartridge housing, if there are no leaks, open main water supply fully.
  7. Flush the new filter with at least 3 or 4 gallons of water or until the water flowing after the filter is clear.
