Buying advice

When selecting a tank ball or rod, ensure compatibility with your toilet's flush valve type (e.g., canister vs. flapper). OEM parts from major brands like Kohler or Toto guarantee a perfect fit, while universal options from Fluidmaster or Korky offer broader compatibility. Consider material quality: brass or stainless steel rods outlast plastic. If unsure, check your toilet model or bring the old part to a hardware store for comparison.
