Get matched with top toilet pros in Genoa, NE

This rumbling noise after flushing may sound like a hammer or knocking inside the walls. When you flush, it opens a valve so additional water can come in. However, if the valve malfunctions, then this rush of water has nowhere to go, which makes all the excess water hit your pipes and create a loud hammering sound.

The cost to install a new toilet typically runs from $225 to $530. This doesn’t include the price of the toilet itself, which can cost $90 to $1,500 depending on the model and features you choose. You can save money if you choose to install a toilet yourself. However, you might want to hire a pro for this project.

"Due to the many complexities of replacing a toilet flange, it is typically a job best left to the pros," says Jeff Botelho, Angi Expert Review Board member and plumber. "Many times it isn't as simple and straightforward as 'pop off the old one and pop on a new one' because the flange is either glued on (PVC/ABS), soldered on (brass/copper), or caulked in place with a lead & oakum joint (cast iron) and none of these things can be easily reversed without years of training and repetitive practice."

If your toilet is still leaking after replacing the toilet flapper, then you may not have installed the toilet flapper correctly. Double-check that you have placed the flapper over the overflow tube correctly, and check the flapper chain is at the right length. If your toilet is still leaking, then you may have another problem on hand. For example, you may need to replace the toilet wax ring or replace the toilet fill valve if your toilet is wobbly and leaking from around the base.

A wax ring can often last the entire lifespan of a toilet, which is typically 20 to 30 years. However, it may need to be replaced sooner if it becomes damaged. Signs that your wax ring needs replacement include bad odors or leaks coming from the base of the toilet. The wax can also dry out, flake, or crumble if the toilet was not secured correctly upon installation or has become loose over time. If you notice your toilet wobbles, it's a good indication that the wax ring may be compromised and should be inspected to prevent leaks.
