Buyer’s Guide – How To Choose The Best Water-Saving Toilets
Buying the best water-saving toilets can be a tough task and should be done with great research beforehand.
To ensure that you get the right toilet, I have a list of factors that should consider before buying them.
Construction of Toilet
The basic construction of the toilet is to be considered before buying it. The toilets are available in one or two pieces.
The one-piece constructed toilet has greater advantages in the long run as it looks more stylish and is easy to clean.
However, it is very heavy in weight and cannot be installed by an average person. There might be a need to hire a professional to install when buying a one-piece toilet.
Another factor you need to consider is whether you require a traditional round-shaped bowl or an elongated bowl.
You need to consider the rough-in as well. It is the distance from the center of the toilet flange to the wall.
The 12-inches rough-in is the standard measurement. However, there are also 10 inches and 14 inches in the market.
Water-saving toilets have two options for the flush; single flush and dual flush. The single flush toilets use 1.6 gallons of water per flush; this is also a law requirement.
The idea behind the dual flush is that it offers options according to waste.
It flushes 1.28 to 1.6 gallons for solid waste, but for the liquid waste, it only requires a half amount that is 0.8 gallons to 1.1 gallons. Therefore, it is very efficient in saving water.
Standard Ratings and Certification
You should check the Maximum Performance ratings (MaP) as they consider the toilet test rating according to the toilet performance.
You should also check the certification of the toilets. Water-saving toilets have a label named ‘WaterSense,’ which proves they have efficiency in water consumption.
Also, check if the toilet you are purchasing is ADA compliant.
