Low Flow Toilets Vs Regular Toilets

Compared to regular flow toilets, low flow toilets flush more powerfully and use less water. It is important to look for a toilet with a high bulk waste removal rating when buying a low flow toilet. Low flow toilets save you significant amounts of water without sacrificing efficiency, thus saving you money on your next utility bill.

In a year, you can save around 9,000 gallons of water by installing a low-flow toilet. Normally, the 3.5 gallons of water are wasted per flush on older toilets. There are low-flow toilets that use much less than 1.6 gallons on average. It can be overwhelming to choose from so many different models of these new toilets which are increasingly popular.

The most common style of toilet is a one or two-piece design. Before one-piece toilets became popular, only two-piece toilets were available. The two perform similarly when it comes to flushing, but they differ significantly in terms of maintenance and price. Low-flow toilets with one piece are easier to maintain.

Regular Flow Toilet

It is very convenient and comfortable to use a two-piece toilet. Additionally, it contributes to the reduction of water and energy consumption. As well as its pros, it has some disadvantages such as the difficulty of cleaning and the fragility of the material. There is a long installation process. The two-piece toilet is difficult to clean and is less durable. The toilet also has water-saving features and a flushing mechanism. Therefore, the cost and weight difference between a one-piece and two-piece toilet.

Flush Rates

Low Flow Toilet

Every flush of a toilet will use a certain amount of water based on the GPF rate. According to current US standards, 1.6 GPF is the maximum flush rate. Despite the fact that 1.6 GPF delivers more water to clean the toilet, some places limit how much liquid can be used per person. When buying a water-saving toilet, keep in mind that it needs to have a GPF rating of 1.28.

Regular Flow Toilet

The Gallons Per Flush rating of a toilet is one of the most important metrics for determining water efficiency. If the GFP of the toilet is 1.28 or less, it is a good choice.  When choosing a toilet, search for a WaterSense certification. This indicates the toilet has been independently verified to conserve water while still providing high-quality performance.

Water Consumption

The flushing performance of low-flow toilets is excellent despite using less than 1.6 gallons per flush. Unless your toilet gets heavy use, you’re concerned about water consumption. Moreover, you may be able to reduce the flush volume to less than 1.28 gallons. If you are planning to buy a toilet for commercial use, it is highly recommended that you purchase one that can handle more than 1.28 gallons since you will need a lot of power.

Regular Flow Toilet

Toilets now use less than half water as older toilets used 3.6 gallons per flush. The advances in hydraulic design have allowed these 1.6 gpf toilets to remove bulk and reduce clogs as efficiently as older toilets. Water consumption for high-efficiency toilets (HETs) is 20% lower than for conventional toilets which flush at 1.6 gallons per flush. It’s easy to save water with our HETs as they perform as well as our 1.6 gpf toilets.

Flushing System

It is important to consider the flushing system when choosing a toilet. As well as the design of the bowl and trapway, flushing power is determined by the mechanism inside the toilet. Most toilets begin with gravity which forces water and waste to flow through a bowl.

The weight of water and the valve connected to gravity flush commodes power the flushing action. Their simplicity, effectiveness and ease of maintenance make them a great choice. The dual flush toilet has a trip lever and a fixed GPF rate. Even though single-flush commodes are more challenging to repair, dual-flush commodes are more effective and cost-effective.

It also performs better and leaves fewer clogs.

  • Low-flow toilets have their outlets situated in the center of the bowl and in the back. Using this method, water is released at a lower rate.

  • Since low-flow toilets are designed to conserve water, they do not have a large flush valve.
