Whether it’s a carbon block filter or a sediment filter that needs replacing, the same rules are applicable – replace the filters at the recommended intervals or whenever the flow rate slows down, whichever comes first. Timely filter replacement will make sure that your water filter system keeps on delivering quality filtered water time and time again.

sediment water filter, replace

Whole house sediment filters are usually used to remove silt, rust, sand and other suspended solids from your entire water supply, thus preventing clogging and breakdowns in your household appliances. Follow these steps to replace the water filter cartridge(s) in your whole house sediment filter:

Preparation

Prepare the new filter and an empty bucket to capture the water that is going to leak when replacing the old cartridge. You may also want to have a bucket with soapy water ready so you can clean out the filter housing since you may not have access to water only after you’ve finished changing the filter.

Shut off water supply

Before you open the filter housing, make sure you turn off the water supply (find the shut off or ball valve located on the line before the filter or turn the pump off on the hydro panel).

Relieve pressure and unscrew the filter housing

Open a tap in your home and let it run until the flow slows down. Then, shut off the valve after the filter housing to prevent water from draining back. Push the release on the top of the housing to make sure that any pressure still remaining in the system will leak out. Take off the filter housing.

Discard the old filter, clean the filter housing and insert the new cartridge

Dispose of the old filter and use the soapy water that you prepared to thoroughly clean the filter housing. Inspect the O-ring to make sure it isn’t stretched or pinched. Coat the O-ring with clear plumber’s silicone grease to make it last much longer and protect against leaks. Insert the new filter cartridge and screw in the filter housing.

Slowly open the inlet and outlet, check for leaks

Slowly open the inlet and outlet, then as you hear water stop flowing, you can fully open the valves. Make sure there are no leaks. If you notice any leaks, you have to shut off the water supply again, de-pressurize the system to tighten up the housing a bit more.

Flush the filters

Open a tap in your house to release the air and let it run for a while to flush the filters.

By following these instructions, you will be able to easily replace your sediment filters whenever necessary.
