Quiet Flush Toilet Buyer Guide: Important Factors to Consider
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.
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.
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 type of flushing system determines how quiet and powerful the toilet will be. There are three primary types of flushing systems:
- Pressure-assisted flush
- Gravity flush
- Dual flush
The pressure-assisted flushing system is mainly found in airplane toilets. They use pressurized air to force water from the tank into the toilet bowl. These are loud and not recommended if you’re looking for a quiet toilet.
Gravity flush uses gravity to force water into the bowl. They are the quietest of the 3 but lack the strength you will find in pressure-assistant toilets.
Dual Flush systems, as the name suggests, have two flushing options. A smaller button allows you to flush liquid wastes while the bigger button is great for flushing solid wastes. With dual flush systems, you have control to the amount of water you expel from the tank.
