Who Should Buy This vs. Who Should Skip

This Kohler GP1105825 Flapper with Float Kit is ideal for owners of Sterling toilets specifically designed for 1.28 GPF flush systems who need a genuine, high-quality replacement part. If your current flapper is leaking, worn out, or causing inefficient flushing, this kit will restore optimal performance. You should skip this if your Sterling toilet uses a different GPF (e.g., 1.6 GPF) or if you have a toilet from a different brand, as compatibility is crucial for proper function. Always verify your toilet's GPF rating and brand before purchasing to ensure a perfect fit.

How to use

  • Prepare for Replacement — Flush the toilet to empty the tank. Turn off the water supply valve behind the toilet and flush again to drain the tank as much as possible. Disconnect the chain from the flush lever.
  • Remove Old Flapper and Float — Carefully detach the old flapper from the overflow tube's mounting pegs. Remove the old float mechanism from the overflow tube or flush valve assembly, noting how it was attached.
  • Install New Kohler Kit — Attach the new Kohler GP1105825 flapper to the overflow pipe pegs. Connect the new float to the overflow tube or flush valve, ensuring it's positioned correctly. Reconnect the chain to the flush lever, adjusting for slight slack.
  • Test and Adjust — Turn the water supply back on and allow the tank to fill. Flush the toilet and check for leaks around the flapper seal. Ensure the float stops the water at the correct level. Adjust chain slack if needed.

FAQ, See What Others Asked

How do I know if my toilet cistern needs a 2-inch or 3-inch replacement flapper?
Measure the diameter of the drain opening at the bottom of your toilet tank with a ruler. Standard older gravity toilets typically measure roughly 2 inches across, whereas modern high-efficiency toilets feature wider 3-inch or 3.25-inch openings to release water faster with lower overall volume. This Kohler kit is for 1.28 GPF Sterling toilets, which usually have a specific valve size.
Why does water keep running into the toilet bowl after installing a new flapper?
A continuous trickle usually means the lift chain is set too tight and holding the flapper slightly open, the chain has excess slack catching underneath the seal, or the flush valve drain seat has mineral scale buildup that prevents the rubber seal from resting completely flat. Ensure the Kohler flapper is seated correctly and the chain has appropriate slack.
Is this Kohler GP1105825 flapper kit compatible with all Sterling toilets?
No, this genuine Kohler GP1105825 flapper and float kit is specifically designed for Sterling toilets that use a 1.28 GPF (gallons per flush) system. Always verify your toilet's GPF rating and brand to ensure compatibility and optimal performance. Using the wrong flapper can lead to leaks or inefficient flushing.
How to buy an original Kohler GP1105825 flapper kit in India?
You can buy the original Kohler GP1105825 flapper kit in India through crowcrowcrow. We import genuine Kohler parts directly from authorized US retailers and brand partners.

What is the difference between this Kohler flapper and local alternatives?
This Kohler GP1105825 is a genuine OEM part engineered for specific Sterling 1.28 GPF toilets, ensuring a perfect fit and reliable flush. Local alternatives may not offer the same precise fit or durability, potentially leading to leaks or premature wear. Genuine Kohler parts provide guaranteed quality and performance.
