What is the standard GPF for toilets?
Standard toilets now flush at a rate of 1.6 gallons per flush (gpf) – which is less than 50% of the water used by older 3.5 gpf toilets. High-Efficiency Toilets (HETs) flush at a rate of 1.28 gallons per flush, saving 20% more water than their 1.6 gpf counterparts.
Is 1.28 GPF a low-flow toilet?
Introduction of Low-Flow Toilets Both 1.28 GPF and 1.6 GPF toilets are considered to be low-flow toilets. The law demanded that toilets sold in the United States should not use more than 1.6 gallons per flush. Before then, most toilets used 3.5 gallons per flush or even as much as 7 gallons.
What qualifies as a low-flow toilet?
A low-flush toilet (or low-flow toilet or high-efficiency toilet) is a flush toilet that uses significantly less water than traditional high-flow toilets. The first standards required low-flow toilets of 6 liters (1.6 gallons) per flush.
What’s the standard GPF rate for a toilet?
It is the unit of measurement used for rating a toilet’s water consumption per flush. Since 1992, a maximum of 1.6 GPF is the Federally mandated standard toilet GPF rate. States with water efficiency standards like Califonia mandate a lower flush rate of 1.28 GPF.
How much water does a 3.5 gpf toilet flush?
3.5 GPF toilet This is an old standard flushing rate that uses 3.5 gallons per flush using a gravitational force. Toilets manufactured between 1980 to 1992 used this flush rate. 3.5 GPF on average means 18.8 gallons of water flushed daily. So that’s a lot of water and dollars down the drain.
Which is better 1.28 gpf or 1.6 gpf?
Toilets that feature a 1.6 gpf are more effective as they clear waste easily in just a single flush. However, even though these toilets use more water, they don’t leave behind stains or have to be flushed twice to clear waste like in some 1.28 gpf toilets. Which is Better? 1.28 or 1.6 GPF?
Which is more common LPF or GPF in bathrooms?
As an alternative way of measuring water consumption, LPF or liters per flush can be used. This scheme is more commonly used in countries where people employ the metric system such as the UK and Australia. GPF, however, is more prevalent in US and Canada.
