Understanding MaP Scores: Choosing a Powerful, Clog-Free Flush Toilet

Learn what’s considered a good MAP rating for choosing a clog-free toilet

If you’ve ever shopped for a new toilet, you’ve probably seen the term MaP score thrown around — often with big numbers like 800g1,000g, or even 1,200g. But what does that actually mean, and how important is it when choosing a powerful, clog-free toilet for your home?

At ToiletKing, we help homeowners cut through the confusion and choose toilets that actually perform. Here’s everything you need to know about MaP scores — in plain English.

Let’s start with the basics. What Is a MAP Score?

MaP stands for Maximum Performance.
MaP score measures how much solid waste (measured in grams) a toilet can flush cleanly in a single flush.

  • Testing uses simulated waste (soybean paste)
  • Toilets are flushed repeatedly
  • The highest weight flushed without clogging becomes the MAP score

The higher the MaP score, the more powerful and reliable the flush.

Why MaP Scores Matter

A toilet’s job is simple: flush once and move everything down — no plunging required. A good MAP score helps ensure:

  • 🚫 Fewer clogs
  • 🚽 No double flushing
  • 💧 Efficient water use
  • 🧼 Cleaner bowls over time

If your household has:

  • Multiple people
  • Kids
  • Guests
  • Or just wants peace of mind

…MaP scores matter a lot.

What Is a “Good” MaP Score?

Here’s a quick guide:

MaP Score What It Means
300–500g Basic performance (older or builder-grade toilets)
600–800g Solid, reliable for most homes
900–1,000g+ Excellent performance, clog-resistant
1,200g+ Top-tier flushing power

👉 ToiletKing Tip: We typically recommend 800g or higher for most households.

Does a Higher MaP Score Mean More Water?

Not anymore. Thanks to modern engineering, many high-MaP toilets use just 1.28 gallons per flush.  In fact, many outperform older 3.5–5 gallon toilets while using less water. Additionally, the are

✔ Powerful
✔ Efficient
✔ Eco-friendly

So, where can you find a Toilet’s MaP Score

MaP scores aren’t always front-and-center, but here’s where to look:

  1. Manufacturer product pages
  2. Specification sheets (PDFs)
  3. Independent toilet reviews
  4. Ask a professional installer (that’s us 😉)

⚠️ If you can’t find a MaP score at all, that’s often a red flag.

MaP Score vs. Flush Type: What Else Matters?

MaP score is important — but it’s not the only factor.

Also consider:

  • Flush system (gravity, pressure-assisted, dual flush)
  • Trapway size (larger = better waste movement)
  • Bowl design (elongated vs. round)
  • Household needs (kids, aging plumbing, guest usage)

At ToiletKing, we evaluate all of these before recommending a toilet — not just the spec sheet.

The ToiletKing Bottom Line

When shopping for a toilet:

  • ✅ Aim for 800g+ MaP score
  • ✅ Don’t assume higher water use means better performance
  • ✅ Look beyond price tags and focus on long-term reliability

And if you don’t want to decode spec sheets or risk buyer’s remorse…
