The amount of water required for a flush in toilets to be effective is called Gallons Per Flush (GPF). It also indicates how to dispose of any waste or water left in the bowl.

What is a GPF in toilets then? GPF toilets are new toilets that have been designed to be efficient. They will tell you the GPF number at the time it is sold. You can see how many gallons it uses by lifting the lid of the toilet tank.

If they have a WaterSense label on the toilet, the WaterSense toilets are likely certified for their efficiency and performance. If the toilet was manufactured before 1992, it is unlikely to be a GPF toilet. It will likely use a lot of water per flush. A toilet with a lower GPF is more efficient.

What is a good GPF for a toilet?

Average toilet flushes require 1.6 gallons of water per flush. This equates to 9.1 gallons daily for average bathroom use. Although this may seem like a lot of water wasted, it is actually a significant improvement over the old toilet designs. The Energy Care Act was passed in 1992, and the current standards for toilets were established. This act banned toilets that used more than 3.6 GPF.

You can go back to 1980 when most toilets used 5-8 gallons per flush. This meant that an average person was using 48 gallons each day at the throne. There are more efficient options than the 1.6 GPF toilets. The newest 1.28 GPF models offer more efficiency.

What does a 1.28 GPF toilet mean?

A 1.28 GPF toilet is the same size as a 1.6 GPF or other toilets. You will not notice any differences in your water consumption. The 1.28 GPF toilet consumes 33.3333% less water than the 1.6 GPF toilet.

It is possible to wonder how much water this toilet will save you each day. This toilet saves you an average of 1.28 GPF per day. That’s roughly 25% of the American population’s daily water consumption.

The amount of water you save per day will increase if you take into account the number of people who use your toilet daily.

A 1.28 GPF toilet is 10 gallons less per day for a family with five people than a 1.6 GPF one. This saves you approximately 3650 gallons per year. This is both more sustainable and easier on your wallet. The 1.28 toilets are quiet and convenient, which is a big advantage if you need to go to the bathroom at night, without disturbing the rest of the family.

Locate Your Toilet’s GPF

It is a good idea to know all information about your plumbing infrastructure. Toilets use approximately 30 percent of the water in your home. Manufacturers understand the importance and will usually list the GPF on the body of the toilet.

You will normally find this information between the tank and the seat. The porcelain usually has a mark that indicates the volume of each flush. If the spot is not marked, the GPF can be found on the underside or inside of the tank. If your toilet was made after 1994, it is likely that your toilet’s gallons per flush measurement are 1.6 GPF. Dual flush toilets might have two GPF measurements. One for liquid flushing and one for solid flushing.

Which is better, a 1.28 or 1.6 toilet?

The 1.28 GPF toilets are high-efficiency toilet that conserves water. However, this toilet is not the best. The 1.28 GPF toilet is a high-efficiency flushing toilet that saves a lot of water per flush. However, there are some disadvantages.

First, low-volume flushes that use less water can cause problems in cleaning out the bowl. If the flush uses less water, it may not remove some waste stains. This is particularly true for toilet paper and solid waste. You may have to flush the toilet multiple times in order to get rid of all the waste and skid marks.

Although this can be solved by flushing twice, it does not negate the benefit of conserving water per flush. You will use 2.56 gallons to flush two toilets, which is much more than what you would use for one flush with a 1.6 GPF toilet.

Fortunately, 1.28 GPF toilet manufacturers have attempted to solve this problem by creating new power flushes that can clean the bowl using the same low-volume flush. Although this helps, it does not eliminate all skid marks.

However, a 1.6 GPF toilet will give you a stronger flush. They use almost 2 gallons less water per day than a 1.28-GPF toilet, but they are also more efficient with their flushes. The 1.6 GPF toilets require only one flush to clean the bowl completely. This means that you won’t have to spend as much time cleaning up those skid marks every week.

These high-efficiency toilet models, however, are louder than the 1.28 GPF ones. This can cause disturbances for other household members who might wake up every time someone flushes their toilet.

Frequently Asked Questions

Which toilet is the best for not clogging

The less likely it is for it to clog, the stronger the flush. According to this logic, a toilet with 1.6 GPF will be less likely than a toilet with 1.6 GPF. What you put in your toilet usually causes the toilet to clog and not the flush power.

Which toilet is the most efficient to conserve water?
