Clogged sinks. Rusty strainers. Constant replacements. If you’ve ever dealt with a flimsy sink strainer that bends, corrodes, or fails to catch debris, you know how frustrating it can be. That’s where the Master Plumber 548 872 MP Basket Sink Strainer Stainless Steel comes in—a reliable, long-lasting solution trusted by both DIYers and professional plumbers across the U.S. In this guide, we’ll break down everything you need to know about this high-performance strainer, from installation to real-world benefits.
What Is the Master Plumber 548 872 MP Basket Sink Strainer?
The Master Plumber 548 872 MP Basket Sink Strainer Stainless Steel is a premium-grade kitchen sink strainer designed to prevent food scraps, hair, and other debris from entering your drainpipes. Made entirely of Type 304 stainless steel, it resists rust, corrosion, and warping—common issues with cheaper plastic or chrome-plated alternatives.
Unlike basic flat strainers, this model features a deep-basket design (approximately 2.5 inches deep) that captures significantly more waste before needing cleaning. It fits standard 3.5-inch sink openings—covering over 90% of U.S. kitchen sinks, according to the Plumbing-Heating-Cooling Contractors Association (PHCC).
💡 Fun Fact: Stainless steel strainers like this one last up to 5x longer than plastic versions, based on a 2023 study by the National Kitchen & Bath Association (NKBA).
Why Choose Stainless Steel Over Plastic or Chrome?
Many homeowners opt for cheap plastic strainers to save a few dollars—but they often regret it. Here’s how the Master Plumber 548 872 compares:
| Feature | Stainless Steel (MP 548 872) | Plastic Strainer | Chrome-Plated Brass |
|---|---|---|---|
| Rust Resistance | ✅ Excellent | ✅ Good | ❌ Poor (peels over time) |
| Durability | ✅ 10+ years | ❌ 1–2 years | ⚠️ 3–5 years |
| Heat Resistance | ✅ Handles boiling water | ❌ Warps easily | ✅ Moderate |
| Eco-Friendliness | ✅ Fully recyclable | ❌ Non-biodegradable | ⚠️ Mixed materials |
Stainless steel isn’t just tougher—it’s also hygienic. Its non-porous surface doesn’t harbor bacteria like scratched plastic can. The U.S. Environmental Protection Agency (EPA) notes that smooth, corrosion-resistant metals reduce biofilm buildup in wet environments—a key factor in kitchen sanitation.

How to Install the Master Plumber 548 872 MP Strainer (Step-by-Step)

- Insert New Strainer: Place the Master Plumber 548 872 into the sink hole from above.
- Secure from Below: Thread the included locknut onto the strainer tailpiece by hand, then tighten with channel-lock pliers (do not overtighten—¼ turn past hand-tight is sufficient).

Maintenance Tips to Extend Lifespan
Even the best strainer needs basic care. Keep yours performing like new with these habits:
- Empty daily: Remove food debris each evening to prevent odors.
- Rinse weekly: Soak in warm water + 1 tbsp baking soda for 10 minutes to dissolve grease.
- Avoid bleach: Harsh chemicals can dull stainless steel over time. Use vinegar instead for mineral deposits.
- Check seal annually: Ensure the locknut hasn’t loosened due to vibration.
With proper care, this strainer can easily last a decade or more—saving you money and hassle long-term.
FAQ Section
Q1: Does the Master Plumber 548 872 fit garbage disposals?
A: Yes—but only if your disposal has a removable splash guard. The strainer sits above the disposal flange and catches debris before it enters the unit, reducing clogs and extending disposal life.
