4 Pack Toilet Flapper Replacement — American Standard VorMax

If your American Standard VorMax toilet is running constantly, making a trickling sound, or your water bill has quietly crept up — the flapper is almost always the culprit. The good news: it's a 10-minute fix, and you don't need a plumber.

This 4-pack of flapper replacements is designed specifically for American Standard VorMax flush valve toilets. VorMax models use a larger 4-inch flush valve opening, which means standard flappers won't seat or seal properly. These are cut to spec for VorMax.

Signs you need a new flapper

• Toilet runs for 30+ seconds after flushing
• Water trickling into the bowl between flushes
• Tank refill cycles seem to start on their own (phantom flushing)
• Higher-than-usual water bill with no other explanation

Compatible Models

Fits American Standard VorMax toilets including Champion 4, Cadet 3, and other American Standard models with VorMax flush technology. Check the model number on the underside of your tank lid to confirm VorMax compatibility.

What's in the box

• 4× VorMax-compatible toilet flappers

No tools required for installation.

How to install

Turn off the water supply valve behind the toilet. Flush once to drain the tank. Unhook the old flapper from the overflow tube ears and detach the chain from the flush handle arm. Snap the new flapper into place, reconnect the chain with about ½ inch of slack, and turn the water back on.

We include 4 in this pack because flappers wear out every 2–5 years. Install one now, store the rest for when you need them — or keep extras for other bathrooms in the house.
