Toilet Flapper Replacement in Gaithersburg, MD

Half the running toilets we see in Gaithersburg have a perfectly good flapper. The water is going over the top of the overflow tube, not under the seal.

Call (301) 395-3831

There are two ways water leaves a tank without a flush. It slips past the seal into the bowl, or the fill valve keeps going and spills down the overflow tube. Telling the two apart takes a minute, and it decides which part gets changed.

What Affects the Cost of Toilet Flapper Replacement in Gaithersburg, MD

No prices appear on this page because every job is different. Setting is sometimes all this needs. A fill valve adjusted too high sends a steady stream down the overflow, and the answer is a float set lower and the level put back where the maker marked it. A valve that won't hold any setting gets replaced, and the seal only comes into it if that's going too.

  • Water level against the mark inside the tank
  • Whether the fill valve holds a setting at all
  • Condition of the seal at the bottom
  • Age of the parts already in the tank

Frequently Asked Questions

Take the lid off and look at the overflow tube, the open pipe standing up in the middle. If water is running into the top of it, the fill valve is at fault and the level is set too high. If the tube is dry and the level in the tank is still dropping, water is going past the seal into the bowl. That one look separates the two.
Only if the valve still shuts where you set it. Lowering a float stops the spill, but if the reason it was raised was a weak flush, you've traded one problem for another and the bowl won't clear. The level belongs about an inch below the top of the overflow tube, and the flush should work there. If it doesn't, something else is wrong and a turn of a screw hides it.
