While WOODBRIDGE flush toilet above may seem like the real deal, there are other options you can choose from. Below is a detailed guide of some other quiet flush toilets you can get on the market. They are a great alternative to the WOODBRIDGE above.
Factors to Consider When Choosing a Quiet Flush Toilet
There are factors to consider before buying a quiet flush toilet. Below are some of the most important factors to take into consideration to get the quietest flush toilet that meets your specific requirements.
Noise Levels
Consider noise levels, particularly if you want to place the toilet close to your bedroom or baby’s nursery. Fortunately, you can gauge the degree of noise depending on the unit’s flushing mechanism.
Generally, gravity-flushed types are the quietest flushing toilets, as their noise levels are the lowest.
However, specific units feature fill valves that make them flush quietly. Regardless, you should consider purchasing flushing toilets with a gentle lid closing that does not slam shut.
One Piece versus Two Piece
The are two primary types of toilets- one- and two-piece toilet. A toilet is made up of 3 main parts- pedestal, bowl, and tank.
One-piece toilets have all the 3 parts infused together and no separation between the toilet and the tank.
Two-piece toilets have the tank and the toilet separate and are only joined together when installing.
There’s no functional difference between the two types of toilets, even though some people believe that one piece is much better than two pieces.
One advantage of the one-piece toilet is the ease of installation. Because they come in one piece, you only need to mount it in one go.
Two-piece toilets need connecting the tank and the toilet. One-piece units are more expensive than two-piece toilets.
Gallons Per Flush (GPF)
Gallons per flush refers to the amount of water your toilet drains per flush. Most modern toilets have a standard of 1.6GPF.
On the other hand, some toilets have a flush system with 1.28-13 gallons per flush, delivering a powerful expulsion force.
If you’re trying to conserve water, consider toilets with low GPF. Unfortunately, most low GPF toilets are noisier than high GPF toilets.
Bowl Shape
Toilet bowl are available in two bowl shapes, with each having its own share of advantages and disadvantages.
The type you choose will depend on the size of your bathroom and personal preferences, and none will affect how loud or quiet your toilet is.
Elongated bowls are longer providing you with more thigh space making your overall experience in the toilet much comfortable. Unfortunately, they take up much space than round toilet bowls and not ideal for smaller rooms.
Round bowls are rounder and much shorter than elongated bowls. They have less thigh space- and they may feel uncomfortable for some people. Luckily, they take less space, making them great for small-sized bathrooms.
The Flushing Technology
There are four central flushing systems. They include pressure-assisted, dual flush, double cyclone commonly known as tornado flush, and gravity flush systems (often the quietest.
Traditional flush systems are gravity-powered, employing the weight of the water to provide flushing pressure. Some gravity systems have an elevated cistern to increase the distance water must travel to the bowl to optimize the pressure created. The tank’s water is directed into the bowl, thus cleaning it and eliminating waste.
Gravity flush systems are among the oldest technologies for flushing toilets, yet their enduring simplicity has allowed them to endure for generations. Due to the limited number of moving parts, they are also one of the quietest flushing systems.
Dual versus Single Flush Systems
Most earlier toilets were single-flush since that was the fashion at the time. With advancements in toilet design and cistern innovation, more environmental concerns have been introduced into toilet design, resulting in the availability of the dual flush option.
Single-flush cisterns are still popular; many now consume less than 1.6 gallons per flush. There are water-saving single-flush cisterns on the market, and for a number of reasons, many people select this choice over a dual-flush system.
Dual flush toilets have a cistern with two flushing mechanisms. Typically, dual flush choices include a full flush (for heavier solid waste) and a half flush (for liquid waste that is less bulky).
The dual flush tends to be partitioned in water usage ratios such as 6/4-liter dual flush, with some having the possibility to be adjusted after installation to be 5/3 or 4/2.6 liter dual flush hence saving you even more water.
To summarize the benefits in a single sentence: dual flush systems save you money and water. The long-term benefits from reduced water use will overcome the short-term cost of converting a single-flush system to a dual-flush system. Occasionally, dual flush systems are also quieter.
