Buying Guide

You have to consider several factors before purchasing a dual flush toilet conversion kit. Let’s discuss those points in this section. Read them to make sure you invest in a compatible kit that suits your purpose.

Button or handle?

Do you prefer a dual flush system with buttons? Or you find the lever mechanism more comfortable to use. The flushing system via handle is comfortable, especially for senior citizens. However, it’s not comparably convenient to use.

The button flushing structure needs a bit more pressure, but it’s long-lasting. On the contrary, the lever-based mechanisms are easy to use but are more fragile. So, pick one as per your requirements.

Compatibility

Invest in a dual flush conversion kit that’s compatible with your toilet. Do you own a 2-piece toilet? Or is it a single piece? Pick a kit according to the design. Check the flush opening size to ensure the new converter fits your toilet without any hassles. In addition, inspect the clearance space. 10-inch is the standard for most of the dual flush conversion kits.

Ease of use

Comfort should be one of your priorities while looking for a dual flush toilet conversion kit. So, check the accessibility of the lever or buttons. Do you want the button on the top? Or do you prefer the lever mechanism on the left or right? Try a kit as per your answers.

Replacement parts

A toilet is used by all your family members. Hence, there are chances that a dual flush conversion kit might break after some time. So, try something that can detect and let you know about leaks because it’s the most common issue. Apart from that, ensure that you can purchase replacement parts in future. These are the two reasons why we suggest kits, which can detect and report the leak.

How to replace my traditional toilet with a dual flush converter?

  • Once the gasket is in its right position, you can snug it up with a cable tie on the sides. But, don’t snug the gasket right now.
  • Break apart the lever or pair of buttons from the rest of its body. Press a lever to take out the buttons set or handle. Unscrew the base, connect the lever with your toilet tank and snug up its nut. Tighten the cable on the gasket.
  • Turn on the water supply and check the flushing mechanism.
  • Change the fill valve if the bowl is not getting enough water to flush down the waste. Loosen the nut that connects the fill valve. You can find it beneath the tank.
