A guide to low flow toilet
Codes of plumbing in some areas require ultra low flow (ULF) toilets. These toilets have recourse to no more than 1.6 litres of water per flush (GPF). Standard toilets used GPF from 3.5 to 7. Located toilets work in most cases as a standard, using steeper parts and superior tanks to increase the speed of the water and to get a lower action toilet.
Replacement of standard toilets with low flow toilets can save between 8,000 and 21,000 gallons of water per year per household. This saves water and reduces the load in the fields of leaching pit septic and municipal sewer systems.
Most low flow toilets use the same principles as standard toilets. One uses compressed air into the tank by the water pressure to accelerate the flow of water. If the system has water under pressure, this model will take long time to recharge and does not generate enough force to work efficiently.
It also noisy, but use less than 1 gallon per flush. Similar models use a conventional compressor compressed air to empty. Listen to these before you buy.
Some plumbers insist that low flow toilets are problems. In the 1980s, some poorly designed toilets were marketed that causes problems. Great strides have eliminated these problems, however. Low flow toilets have been used in Europe for over 20 years without problems sewer going back to them.
Today are basically United States standard. When you purchase, make sure that the toilet is a type of “ultra low flow”, not a “water protective,” which is simply another name for the toilet standard 3.5-GPF or “low flow”.
