A toilet that runs constantly is almost always the flapper, the rubber seal at the bottom of the tank. It is a quick fix and one every Waukesha homeowner can learn.
How the flapper works
When you flush, the flapper lifts to let tank water rush into the bowl, then drops back to seal the opening. Over time the rubber warps, cracks, or collects mineral buildup, so it no longer seals and water leaks into the bowl nonstop.
Confirm it is the flapper
Put a few drops of food coloring in the tank and wait 15 minutes without flushing. If the color shows up in the bowl, the flapper is leaking. In Waukesha homes with hard water, the test is worth doing once a year.
The swap is simple
Shut off the water, flush to empty the tank, and unhook the old flapper from the flush valve. Clip the new one in place and reattach the chain with about a half-inch of slack so it closes cleanly.
Pick the right part
Flappers come in a few sizes, and a universal model usually fits, but matching the original is safest. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes A pro can identify the right one in seconds if the parts aisle is confusing.
