Falls Church starts mild this week: highs near 64°F on Sunday, in the low 70s by Tuesday, and cool nights in the mid-40s. Showers are expected late Wednesday and on Thursday. Use this calm stretch to check your whole-home water filter.
How a Whole-Home Filter Works
A whole-home filter treats water as it enters your home. Depending on the type, its cartridge may trap sediment or reduce certain substances. Sediment build-up can slow the flow. Other media can lose effectiveness, with no change in pressure, taste, or look.
A basic visual check usually needs no tools. Never loosen or remove a housing while it is pressurized — checking is not opening the unit — and only open it as the manufacturer’s instructions show. Some systems need professional servicing, not a homeowner change.
Steps to Check Your Whole-Home Water Filter
Here are simple steps you can take this week:
- Notice the signs. Lower flow at several taps may mean a filter restriction or another supply issue. Changes in taste, smell, or appearance should be investigated, not blamed on the filter.
- Check the change date. Compare the last change date with the manufacturer’s schedule for your model. If it is past that date, replace it following the manufacturer’s instructions, even if the water seems fine.
- Look, but do not force anything. If your model has a clear housing, look for build-up, but appearance alone cannot show whether the filter still works. Do not open a stuck or leaking housing.
- Replace with the specified cartridge. Follow the manufacturer’s steps for shutting off the water, releasing built-up pressure, and fitting the new cartridge. If you cannot identify the correct shut-off or safely release the pressure, stop and contact a professional.
- Check for leaks and write the date down. Make sure the housing is seated and sealed as the manufacturer directs, follow its flushing steps, and check for drips as the system returns to service, and write the new date where you will see it.
When to Call for Help
If pressure drops suddenly, the water changes color, or a housing will not stop leaking, shut off the water if it is safe and you know the correct shut-off, and have the system checked. For an unexplained change in color, taste, or smell, contact your water supplier — do not assume a new cartridge fixes it. Follow any drinking-water advisory from your supplier rather than relying on your household filter, which only reduces what its model is designed and certified to reduce.
