Quiet Flushing Toilet Adjustments (From Loud to Quiet)
The sound of water hitting pipes or porcelain creates amplified echoes that can account for loud flushing. Think about what happens when you partially place your thumb over the opening of a garden hose- not only is the spray pressurized because of the obstruction, but the sound of the water spraying out of the hose becomes louder, and changes pitch.
The same thing happens in your toilet, except instead of the water spraying into empty space, it’s hitting metal or porcelain, creating a loud, echoing flush – here are some potential causes and tips on how to resolve them.
One cause of these noises can be water filling up a large toilet tank. As the water fills the formerly empty space, it gurgles loudly, with the remaining air in the cistern amplifying the sound.
✓ The Fix: If your toilet has a large tank, consider placing a brick inside of it to displace some of the volumes, lowing echo capacity.
- As an alternative, you can soundproof your tank. First remove the tank lid, placing adhesive foam tape around the edges of the tank, where the lid sits, replacing the lid and firmly pressing it into place. This creates a tight, soundproof seal between the lid and tank. You can also soundproof any exposed pipes by wrapping them in acoustic-absorbing foam.
Restricted, tight, or stiff valves impact water pressure, causing a loud flush or tank refill. Water may also make noise when it is forced to trickle into the tank too slowly because of a restricted or closed water supply valve.
✓ The Fix: Install a quiet-fill valve. These flush valves fill the toilet tank below the waterline, minimizing any gurgling. Check out this video to see how simple and easy it can be to replace a fill valve.
Obstructions may cause an increase in water pressure, resulting in loud echoes. When a pipe or valve is restricted by a clog or obstruction, the water will manage to trickly through slowly, gurgling into empty space, rather than smoothly flowing in.
✓ The Fix: Eliminate obstructions by plunging the toilet or snaking the trap way and cleaning or replacing valves.
- As an alternative, alter the water pressure by partially lowering the water supply. Note that the tank will fill slower, potentially resulting in gurgles.
This one might seem obvious buy over time, bolts and screws on your toilet might come loose, causing increased noise.
✓ The Fix: Eliminate flushing vibrations by examining and tightening all bolts on the unit. Don’t forget to check the screws holding your seat and lid in place too!
When refill pipes are placed at sharp angles, water may hit the pipe corner at a high speed when it rushes in to refill the cistern, causing a loud banging noise.
✓ The Fix: Correct sharp angles in pipes by swapping out angled pipes for rounded corners or adjusting angle adapters.
This video examines some of the problems we have mentioned and shows how to fix them. The plumber replaces a fill valve, dislodges debris and obstructions from the water supply piping, and replaces a faulty shut-off valve.

2. TOTO UltraMax II
The TOTO UltraMax II offers a lot of useful features as well as great efficiency and performance. Its one-piece construction allows you to clean and maintain the bowl with ease.

Always a good sign when customers come back and purchase a second one, which is the case with this toilet. While a couple of reviewers mention clogging issues, most are happy with the powerful flush of this toilet. The one-piece design offers a sleek, modern look that customers love.
3. Niagara Stealth Toilet
Do you need an extremely long-lasting, yet efficient low-flow toilet? The Niagara Stealth may be the perfect choice for you. With water consumption of only 0.8 GPF, it is the most efficient toilet in its class. Toilets like this one can last up to 30 years because of the way they operate. The Niagara Stealth is also well-known for being quiet, which is not something we wouldn’t expect from a gravity flush toilet.
One downside to the Niagara Stealth is maintenance. Since it’s a two-piece construction it might be more difficult to clean between the pieces. On the other hand, the seat height of this toilet is about 18 inches, ideal for people with disabilities and the elderly. Although it seems impossible for a toilet with such low consumption to clean the bowl entirely, the gravity-assisted technology ensures all the waste is gone after a single flush.

This toilet packs a powerful flush which lends itself to being easy to clean which is always a plus! Customers like water efficiency, especially because it doesn’t impact performance. While the seat was too tall for some users, overall buyers agree that the seat is a comfortable feature!
4. Kohler Santa Rosa
The Santa Rosa toilet is one of Kohler’s most comfortable toilets. The oblong shape and the right height 17-inch seat play an essential role in comfort.

The construction of the Santa Rosa is long-lasting and durable. This toilet consumes 1.6 GPF, making it EPA WaterSense certified.
Unfortunately, due to the one-piece design, the toilet is heavy, weighing in at 109 pounds. Still, with the standard 12-inch rough-in, it is pretty easy to install. The Kohler Santa Rosa will easily complement almost any bathroom and comes in four colors: classic white, almond, dune, and black. Since this toilet uses gravity flush technology, it is also pretty quiet.
