Kohler Toilet Replacement Parts for the Pompton Toilet
One-Piece Model # K-3400

Pompton Toilet repair parts diagram

Kohler transitioned from the old style to the new style parts in 1973
We are offering parts for the New Style float valve kit (#13 & #14 are still available from the old style)

Please Note: There are only slight differences between the two styles. The plungers (#4 and #6) in the old style are different than the plungers (#3 and #5) in the new style. The other difference is where the tank ball lift wire guide is located. The new style has the lift wire guide attached to the refill tube and the old style has the lift wire guide attached to a post on the flush valve seat.

If your tank ball lift wire guide is attached to the refill tube then you have the new style and the plunger parts you will need are the #5 (#51429) plunger only or the #3 (#30166) valve service kit. If your tank ball lift wire guide is attached to a post on the flush valve seat then you have the old style and the plunger parts you will need are the #6 (#51748) plunger only or the #4 (#30100) plunger service kit.

Frequently Asked Questions

Q. "How do I find my Kohler model number?"
A. For our customers' convenience, we list both the model number and the tank number of the Kohler toilets we offer parts for. If you already know your model number, that's great - but oftentimes this information won't be available to you. What you'll need to do then is look for the TANK number, which is right where you'd expect it to be on the inside of your toilet tank. Grab a flashlight, carefully remove your tank lid, place your lid somewhere safe, and look around inside your toilet tank for a 4-digit number beginning with either a 3 or a 4. Certain specialty toilets may have a 5-digit number starting with a 1. The number will be either molded into the porcelain or stamped on in blue or black ink. This is your tank number and you can use it to find the parts you need to fix your toilet.

Q. "There are letters and/or numbers after the model number inside my Kohler toilet tank - what do those mean?"
A. Kohler offers many variations of almost all their toilet models, and has experimented in the past with many different features. Typically, numbers (or a single letter/number combination like K4 or Y2) after the 4- or 5-digit model number indicate the color code for your toilet. If your model number is followed by letters, those usually have different meanings to indicate the features of your toilet or will indicate that you have a specialty Artist Edition toilet.
