Water quality is a fundamental concern for every US homeowner, yet many overlook the source until issues arise. Whether you are dealing with sediment, chlorine taste, or potential contaminants, finding a reliable solution is crucial for your family’s health and appliance longevity. The American Plumber Whole House Water Filter 20 Inch stands out as a robust, professional-grade choice designed to handle high flow rates while delivering superior filtration performance.
In this comprehensive guide, we will explore why this specific model is a favorite among plumbers and DIY enthusiasts alike. We will break down its features, installation process, and maintenance requirements to help you make an informed decision.
Why Choose a 20-Inch Whole House Filter?
When selecting a whole-house filtration system, size matters significantly. The “20-inch” designation refers to the length of the filter cartridge and the housing unit. But why is this size often recommended over the standard 10-inch models?
Superior Flow Rate and Pressure Retention
The primary advantage of a 20-inch filter is its surface area. A larger filter cartridge provides more media for water to pass through. This means:
- Higher Flow Rates: It can handle the simultaneous use of multiple fixtures (showers, washing machines, dishwashers) without a noticeable drop in water pressure.
- Longer Service Life: Because there is more filtration media, the filter does not clog as quickly as smaller units. This translates to fewer cartridge changes and lower long-term maintenance costs.
According to industry standards, a 20-inch big blue housing can typically support flow rates of up to 20–25 gallons per minute (GPM), which is sufficient for most average-to-large US households. In contrast, standard 10-inch filters may struggle to maintain pressure when multiple taps are open.
Versatility in Filtration Types
The American Plumber 20-inch housing is compatible with various cartridge types, allowing you to customize your filtration based on your local water quality report. You can choose from:
- Sediment Filters: To remove dirt, rust, and sand.
- Carbon Block Filters: To reduce chlorine, bad tastes, and odors.
- Combination Filters: For comprehensive protection against both particulates and chemicals.
Key Features of the American Plumber System
American Plumber has built a reputation for durability and reliability. Their 20-inch whole house systems are engineered to meet the rigorous demands of residential plumbing.
Durable Construction
The housing is typically made from high-quality, reinforced polypropylene. This material is resistant to corrosion and can withstand varying water temperatures and pressures. The heavy-duty design ensures that the unit will not crack or leak under normal operating conditions, providing peace of mind for years.
Professional-Grade Components
Unlike budget-friendly alternatives, American Plumber units often come with:
- Stainless Steel Reinforcement: Many models feature a stainless steel ring at the base for added stability.
- High-Quality O-Rings: To ensure a watertight seal and prevent leaks during operation.
- Pressure Relief Valve: A crucial safety feature that allows you to safely release pressure before changing the filter cartridge.
For more detailed information on water quality standards and contaminants, you can refer to the Environmental Protection Agency (EPA) guidelines, which provide extensive data on safe drinking water limits in the United States.
Installation Guide: Step-by-Step
Installing a whole-house water filter can seem daunting, but with the right tools and preparation, it is a manageable DIY project. Always consult a licensed plumber if you are unsure about your local plumbing codes.
Tools Needed:
- Pipe cutter or hacksaw
- Adjustable wrenches
- Teflon tape
- Bucket and towels
- Measuring tape
Step 1: Shut Off the Water Supply Locate your main water shut-off valve and turn it off. Open a faucet on the lowest level of your house to drain any remaining water and relieve pressure.
Step 2: Choose the Location Install the filter after the main shut-off valve but before the water heater. This ensures that both hot and cold water lines are filtered (if using a whole-house system) or just the cold line if specified. Ensure there is enough vertical clearance (at least 24 inches) to remove the housing for filter changes.
Step 3: Cut the Pipe Measure and cut the main water line where the filter will be installed. Use a pipe cutter for a clean edge. Deburr the edges to prevent damage to the fittings.
Step 4: Install the Bypass Loop (Recommended) A bypass loop allows you to isolate the filter for maintenance without shutting off water to the entire house. Install three ball valves: one before the filter, one after, and one on the bypass line.
Step 5: Connect the Filter Housing Attach the inlet and outlet ports of the American Plumber housing to your plumbing lines. Use Teflon tape on all threaded connections to ensure a leak-free seal. Tighten securely but avoid over-tightening, which can crack the plastic.
Step 6: Insert the Cartridge Remove the sump (bottom part) of the housing by turning it counter-clockwise. Insert the 20-inch filter cartridge into the housing. Ensure the O-ring is properly seated and lubricated with silicone grease if necessary. Reattach the sump and tighten.
Step 7: Test for Leaks Slowly turn the main water supply back on. Check all connections for leaks. If using a bypass, ensure the filter is in the “on” position. Let the water run for a few minutes to flush out any carbon fines (if using a carbon filter).
Maintenance and Cartridge Replacement
Proper maintenance is key to ensuring your American Plumber Whole House Water Filter 20 Inch performs optimally. Neglecting maintenance can lead to reduced water pressure and potential bacterial growth.
How Often Should You Change the Filter?
The frequency depends on your water quality and household usage. However, general guidelines suggest:
- Sediment Filters: Every 3–6 months.
- Carbon Block Filters: Every 6–12 months.
Tip: Monitor your water pressure. A significant drop in pressure is a clear indicator that the filter is clogged and needs replacement.
Cleaning the Housing
Every time you change the cartridge, take the opportunity to clean the housing.
- Remove the old cartridge and dispose of it properly.
- Wash the inside of the housing with mild soap and warm water.
- Inspect the O-ring for cracks or wear. Replace it if necessary.
- Lubricate the new O-ring with food-grade silicone grease to ensure a good seal.

Frequently Asked Questions (FAQ)
1. Does the American Plumber 20-inch filter remove lead?
Standard sediment and carbon filters do not specifically remove lead unless they are certified for it. To remove lead, you need a cartridge specifically rated for lead reduction (NSF/ANSI Standard 53). Check the specific cartridge specifications before purchasing.
2. Can I install this filter outdoors?
While the housing is durable, it is recommended to install the filter indoors or in a protected area. Extreme temperatures (freezing or direct intense sunlight) can degrade the plastic and affect the filter media’s performance. If outdoor installation is necessary, use an insulated cover.
3. Will this filter lower my water pressure?
All filters create some resistance. However, the 20-inch size is designed to minimize pressure loss. If you experience a significant drop, check if the filter is clogged or if the cartridge type is too dense for your flow requirements. A 5-micron sediment filter will have less impact on pressure than a 1-micron filter.
4. Is professional installation required?
No, professional installation is not strictly required if you have basic plumbing skills. However, if you are uncomfortable cutting into your main water line or if your local codes require a licensed plumber, it is best to hire a professional.
5. What is the difference between a 5-micron and a 1-micron filter?
The micron rating refers to the size of particles the filter can remove. A 5-micron filter removes larger particles like sand and rust. A 1-micron filter removes finer particles, including some bacteria and cysts. For most municipal water supplies, a 5-micron sediment pre-filter followed by a carbon block is sufficient.
Conclusion
