Is your shower pressure dropping, or are you noticing strange particles in your tap water? These are common signs that your whole-house filtration system is struggling to keep up with sediment buildup. Installing the American Plumber W20CLA Whole House Sediment Filter Cartridge 2-Pack is the most effective solution to restore water clarity and protect your expensive appliances from grit and rust. As a homeowner, ensuring clean water isn’t just about taste; it’s about safeguarding your entire plumbing infrastructure.
What Exactly Is the American Plumber W20CLA Filter?
The American Plumber W20CLA Whole House Sediment Filter Cartridge 2-Pack is a high-capacity filtration solution designed to remove dirt, sand, rust, and silt from your main water supply before it reaches your faucets. Unlike point-of-use filters that only treat water at a single sink, this system protects every drop of water entering your home.
These cartridges are typically 20 inches in length, offering a larger surface area than standard 10-inch filters. This extended size means they can hold more contaminants before needing replacement, making them ideal for homes with higher water usage or particularly dirty well water. The “CL” in the model number often denotes a specific pleated design, which increases the filter’s efficiency by folding the material to create more surface area within the same footprint.
According to general water quality standards, sediment is one of the most common primary contaminants in municipal and well water systems. By using a pleated spun polypropylene filter like the W20CLA, you are utilizing a industry-standard method for mechanical filtration. You can read more about the general principles of water filtration and sediment types on Wikipedia.

Why Do You Need a Whole House Sediment Filter?
Many homeowners assume that if their water looks clear, it is free of particles. However, microscopic sediment can still pass through older pipes or enter via municipal line repairs. Without a robust barrier, these particles accumulate in your water heater, washing machine valves, and faucet aerators.
The Hidden Costs of Unfiltered Water
- Appliance Longevity: Sediment acts as an abrasive. Over time, it wears down seals and valves in dishwashers and washing machines, leading to premature failure.
- Energy Efficiency: In water heaters, sediment buildup at the bottom of the tank creates an insulating layer. This forces the heater to work harder to warm the water, increasing your energy bill by up to 10-15%.
- Staining: High iron or rust content can leave unsightly orange or brown stains on sinks, tubs, and laundry.
By installing the American Plumber W20CLA Whole House Sediment Filter Cartridge 2-Pack, you create a first line of defense. Think of it as an air filter for your home’s lungs; it breathes in the water and exhales purity.
How to Install the W20CLA Cartridge: A Step-by-Step Guide
Replacing or installing these filters is a straightforward DIY project, but precision matters to prevent leaks. Follow these concrete steps to ensure a secure fit.
Tools Required:
- Filter wrench (usually included with the housing)
- Bucket or towels
- Silicone lubricant (food grade)
- Teflon tape (if re-threading connections)
Installation Steps:
- Shut Off the Water Supply: Locate the main shut-off valve for your house and turn it clockwise to stop the water flow. Open a faucet on the lowest level of your home to relieve pressure in the lines.
- Remove the Old Housing: Place a bucket under the filter housing to catch residual water. Use the filter wrench to turn the sump (the bottom bowl) counter-clockwise. Be careful; it may be heavy with water.
- Clean the Housing: Empty the water and inspect the inside of the sump. Wash it with mild soap and warm water (approx. 2 liters of water, temperature 22–28°C) to remove any slime or loose debris. Rinse thoroughly.
- Inspect the O-Ring: Check the black rubber O-ring on the housing head. If it is cracked or flat, replace it. If it looks good, apply a thin coat of food-grade silicone lubricant to ensure a watertight seal.
- Insert the New Cartridge: Take one American Plumber W20CLA cartridge from the 2-pack. Place it onto the central post inside the housing head. Ensure it sits flush and straight; do not force it.
- Reattach the Sump: Screw the sump back onto the head by hand first to avoid cross-threading. Once tight, use the wrench to give it an additional quarter turn. Do not overtighten, as this can crack the housing or distort the O-ring.
- Flush the System: Slowly turn the main water supply back on. Let the water run through a utility sink or outdoor spigot for 2–3 minutes. This flushes out any loose carbon fines or air pockets. Check for leaks around the housing.
American Plumber W20CLA vs. Generic Alternatives
Not all filters are created equal. While generic brands might seem cheaper upfront, the long-term performance often differs. Here is how the American Plumber brand stacks up.
Comparison Table
| Feature | American Plumber W20CLA | Generic Economy Brand |
|---|---|---|
| Material Quality | High-grade polypropylene, resistant to bacteria growth | Variable quality, sometimes prone to compaction |
| Flow Rate | Optimized for high flow without pressure drop | Often restricts flow significantly as it loads |
| Filtration Consistency | Uniform pore size for reliable micron rating | Inconsistent pore distribution |
| Durability | Designed to last 3-6 months depending on usage | May collapse or channel after 1-2 months |
| Price Value | Higher initial cost, better longevity | Lower cost, frequent replacement needed |
Expert Insight: In the filtration industry, “channeling” is a common failure mode where water finds a path of least resistance through a cheap filter, bypassing the filtration media entirely. The pleated design of the American Plumber W20CLA minimizes this risk by maintaining structural integrity even under high pressure.
Maintenance Schedule: When to Replace Your Filter?
One of the most common questions we receive is, “How often should I change my filter?” The answer depends entirely on your water quality and household size.
- Standard Recommendation: Every 3 to 6 months.
- High Sediment Areas: If you are on well water or live near construction, you may need to change it every 1 to 2 months.
- Visual Check: If the white cartridge turns dark brown or black, it is time for a change. If it looks grey but flow rate hasn’t dropped, it can likely stay in service.
Pro Tip: Buying the American Plumber W20CLA Whole House Sediment Filter Cartridge 2-Pack is a strategic move. It ensures you have a spare ready immediately when the first one clogs, preventing any lapse in protection. Mark your calendar or set a phone reminder for the installation date to stay on track.
Frequently Asked Questions (FAQ)
1. What is the micron rating of the American Plumber W20CLA?
The specific micron rating can vary slightly by production batch, but these cartridges generally function effectively in the 5 to 20-micron range. This makes them perfect for capturing sand, silt, and rust while maintaining strong water pressure throughout the house.
2. Will this filter remove chlorine or bad tastes?
No, the W20CLA is a sediment filter. It is designed to remove physical particles, not chemicals. To remove chlorine, VOCs, or bad tastes, you would need a subsequent stage of filtration, such as an activated carbon block filter, installed after this sediment pre-filter.
3. Can I wash and reuse the W20CLA cartridge?
No, these are disposable cartridges. Attempting to wash them with water or chemicals will damage the pleated structure and compromise the micron rating. Once dirty, they must be replaced to ensure water safety and pressure.
4. Is the W20CLA compatible with other brand housings?
Yes, as long as the housing is a standard 20-inch “Big Blue” style. The American Plumber W20CLA adheres to industry-standard dimensions, making it compatible with most major housing brands like DuPont, Pentair, and generic big blue housings found at hardware stores.
5. Does installing this filter affect my water pressure?
Initially, there may be a negligible drop in pressure (usually less than 1-2 PSI), which is normal for any filtration media. However, because the W20CLA uses a pleated design, it maintains higher flow rates compared to spun filters. If you notice a significant pressure drop, it is a sign the filter is clogged and needs replacement.
6. Is this filter safe for well water?
Absolutely. In fact, the American Plumber W20CLA is highly recommended for well water applications where sediment, sand, and iron rust are common issues. It serves as an essential pre-filter before any UV sterilizers or softeners.
