If you want a Filter/Bypass Valve, which doesn't shut the water off to the rest of your house, try the U30

Because of the product’s limited service life and to prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately. Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
