Whether you’re renovating your toilet, getting a new toilet or something better, it’s worth spending time going over dual flush vs single flush toilets. Typically, single flush toilets are found in older houses and most buildings. There’s the same amount of water per flush regardless of the type of waste being disposed of.

This article will show you the difference between single and dual flush toilets. You should understand the key features to be wise in making a purchasing decision.

Double flush toilets need 1.6 gallons for full flash and only 0.8 gallon for a half flush. The full flash is dedicated to flushing down solid waste while the half flush is for clearing liquid waste or urine.
That’s why there are two buttons on dual flush toilets for the two flush options. When there are only a few users, it works the best. This setup will let you save water and lower your water bill. A single flush is suitable in high-traffic areas like busy public restrooms that have multiple users.
