Frequently Asked Questions
My Kohler toilet keeps running. What part do I need?
Start by checking your flapper or flush valve seal. A slow leak from either of these parts is the most common cause of a running toilet. As water slowly leaks from the tank, it triggers the fill valve to turn on to replace the lost water. If replacing the flapper or seal doesn't fix it, the fill valve is the next part you should replace.
How do I know which fill valve fits my Kohler toilet?
Korky fill valves fit 99% of toilets, so any of our models will work. The difference between models is based on performance features:
- 528 - QuietFILL Fill Valve (white cap) — our standard quiet-fill valve.
- 528MP - QuietFILL Platinum (silver cap) — adds a refill adjuster that fine-tunes bowl water level to match your toilet's original performance.
- 528X - 2X Long-Life Fill Valve (black cap) — includes the refill adjuster plus a 2X longer-lasting material, backed by a 10-year warranty.
Does Korky make a repair kit for Kohler toilets?
Yes - Korky offers kits that include a fill valve and toilet flapper replacement in both standard 2-inch and large 3-inch sizes. Just be sure to measure your flush valve opening before heading to the store.
