Review: When you think you need this, you probably do. It works great! - Not much to say, other than it fixed poor flushing on a Flushmate toilet in about two minutes start to finish.
Review: Great replacement part. - This fixed my problem. A quick Google search and a part number search sent me to them to buy a single one. Most people say it doesn’t last maybe next time I’ll buy a four pack but very happy my toilet flushes again like it’s supposed to

## Questions & Answers

**Q: How many are in the package?**
A: Only one. It works. It fixed my problem but it is way over priced. If I could have found one cheaper somewhere else I would buy somewhere else. I think a reasonable price would be $1.

### ⭐⭐⭐⭐⭐ A simple fix! Exactly what I needed!
*by J***E on January 11, 2017*

This little valve was exactly what I needed to fix our Flushmate pressurized toilet! Saving us $ from calling a plumber. A super simple fix, anyone can do it! Just look up "Toubleshooting Flushmate" on YouTube, or take a look at the photo i included. The duckbill valve gets set inside the cap labeled "D" and then you just screw the cap back on. VERY IMPORTANT, only hand tighten the cap back on. Don't use any tools. Over-tightening the cap can damage the duckbill valve or cause it to bend and not suck in air properly. The valve was (and should be) very inexpensive. Dont overpay for a replacement!
