## Questions & Answers

**Q: anyone know of a video that shows how to take out the old assembly and put this one in?  I can find only videos on replacing just the flapper.**
A: Here's a video showing the installation process.  https://www.youtube.com/watch?v=_96_yx3-boQ

Where this fellow says to use Olive Oil as a lubricant I used Hayward Pool and Spa Lube on both sides of the new seal. Otherwise the removal and installation process I used is exactly as shown in the video.

**Q: what is the flush valve kit for k3435 toilet**
A: K-3435 toilets had several different versions during production. To distinguish the different versions of the toilets, a letter code was stamped on the backwall of the tank after the model number (example: 3434-AB). The different versions include AA, AB, BB or FB.

Each version of the toilet had a different style flush valve, as indicated below.

 

Toilet Version	Part Number
AA                           Flush Valve 83093

AB	                        Flush Valve 83486

BB	                        Flush Valve 83664

FB	                        Flush Valve 86972

**Q: Will it work for a Kohler 3397EB?**
A: I doubt it. Checked models online and yours doesn’t come up on the list of models this valve fits.

**Q: Does this fit a Kholer K3451 toilet?**
A: Depending on the height of the black tube is what you looking for. 
Be sure it is the same as yours. But should work.
