Whole House Water Filter Housing

The water filter housing is possibly the most easily overlooked of all the water filtration system components. This “unlikely hero” of water filtration systems is a vital component that holds your real filter in place so that water can travel through it without any particles or unwanted chemical additives. A good whole house water filter housing replacement can offer you quality water that’s safe and clean.


First, let’s start with some important care tips for whole house water filter housing.

  • CAREFULLY HANDLE: Avoid scratching, banging, or dropping the item so you keep it in good shape.
  • SUNLIGHT: Always use blue bowls instead of clear bowls when there is UV exposure.
  • PROTECTION AGAINST FREEZING: Avoid freezing as it may deteriorate the quality of the housing and water.
  • KEEP IT AWAY FROM CHEMICALS: Do not expose household chemicals and solutions like aerosol sprays, cleaning products, or insecticides.
  • NEVER EXCEED MAX PRESSURE RATING: If pressure surges are a concern, use a pressure-lowering valve to keep things under control.
  • FILTER BOWL REPLACEMENT: Clear bowls should have replacement every five years. Blue bowls, on the other hand, should have replacement every ten years. So, if you’ve been using your bowl for longer than the recommended time, it’s time to replace it. Make a note of the date on the bowl for future reference.

Caution: All filtering systems have parts with a finite service life that are difficult to track. As a result, position filter housings where property damage from leaking is unlikely.


Big Blue housings are available with or without a pressure relief button. Moreover, it’s suitable for a wide range of chemicals. They accommodate a wide range of cartridges with a diameter of 4 1/2″.

Big Clear Filter Housings are perfect for a range of applications because they allow for on-site evaluation of flow, performance, and cartridge life. When changing filter cartridges, the blue polypropylene caps come with an optional pressure-relief button on the intake side to relieve pressure inside the housing.

Valve In-Head Housing

Valve-in-Head housings’ durable design and application features are the same as our Standard 3/4″ NPT housings.

With a half-turn of the handle, the internal valve-in-head may shut off both the inlet and outlet ports simultaneously. It no longer requires external shut-off valves. Each time you use the valve, it continually cleans the radial sealing O-rings and sealing surfaces. It assures leak-free operation.

Valve-in-head filter housings come in 10-inch and 20-inch lengths, with reinforced polypropylene or transparent FDA-compliant Styrene-Acrylonitrile (SAN), sumps to handle a wide range of 2-3/8″ to 2-7/8″ diameter cartridges.

Standard Housings

Filter housings use polypropylene or clear Styrene-Acrylonitrile (SAN). 3/4″ FPT intake and outlet ports are standard on all.

Chemical resistance is good in reinforced polypropylene housings, making them perfect for various residential, commercial, and industrial applications. Clear sumps use clear, FDA-approved Styrene-Acrylonitrile (SAN) and allow on-site cartridge inspection. Standard filter housings are available in 10-inch and 20-inch lengths and will fit a variety of 2-1/2″ and 2-7/8″ cartridge diameters.

Multi-Housing Units

Basic Filtration Systems (BFS and BBFS) make up two or three filter housings mounted in series. It works as well as a wall-mounting bracket and hardware.

The BFS-201 is a set of low-profile 3/8″ NPT Slim Line housings for installations with limited space. The BBFS systems are made up of a succession of large-capacity 1″ NPT 20″ Big Blue housings that allow for larger flow rates and cartridge capacities. All methods include a pressure relief button to reduce housing pressure during cartridge changes, and they are delivered fully built.

All of the housings use tough polypropylene as the main material. It’s chemically resistant and suitable for residential, commercial, and industrial uses.

What Other Accessories or Replacements Do I Need for a Whole House Water Filter?

Water Filter Housing Kits are commonly available, ensuring that the filter housing comes with the necessary attachments. They include one O-ring that has been installed and one replacement O-ring, mounting brackets and hardware, and a filter bowl wrench.

You can find parts with a limited service life in all filtering systems, independent of the manufacturer. As a result, you must put filters in a location where leaks will not cause property damage. Choose an area where there’s a sufficient drain to handle the amount of water produced by the system.

How Often Should I Replace The Housing?

Manufacturers strongly advise that all plastic housings’ bowls (or sump) be replaced regularly: for clear bowls and opaque bowls every five years. If you’ve been using your bowl for longer than the recommended time, it’s time to replace it. Any new or replacement bowl should have a date for future reference.
