Converting a single flush toilet to a modern eco-friendly dual flush one is a simple DIY task that you can do all by yourself in a few minutes by following a few steps.
All you need is a perfect dual flush conversion kit and the know-how on how to do it as you will learn hereby and you’re all ready to go.
Before you begin the conversion replacement procedure you should take a few measurements from the existing toilet tank so as to get the perfect kit compatible with your tank. These measurements are the tank height and the diameter of the flush valve
Single flush toilet systems come in several models and design both which can affect the dictate compatibility and make the installation processes vary a little although the basics still remain the same.
Once you’ve decided which dual-flush conversion kit is right for you, purchase it and get it ready. It is important that you make sure the kit comes with an installation manual as it will help you as per the model.
Below is a generalized procedure for the conversion of a single flush system to dual flush system:
- To start off, first, turn off the water supply valve behind the toilet to prevent further inflow of water into the tank.
- Flush the toilet a few times to remove as much water as you can from the tank then take off the toilet lid and place it aside.
- Next, disconnect the existing flush mechanism, take them off and place them aside. Basically in most toiles, they are the flapper valve, chain and flush handle.
- Disconnect the fill tube from the overflow tube and slide in the new dual flush unit. A new flush tower mechanism will be included in your conversion kit, which will fit right over your existing overflow tube. A rubber washer and zip tie are typically provided to secure the mechanism, ensuring that the new flush unit is properly seated over the flush valve.
- Remove the existing flush lever from the toilet tank and install the new dual-flush flush lever or button mechanism through the hole where your flush handle used to be. To do this, disassemble the new push button or lever actuator and fasten it to the toilet tank then reconnect the dual-flush mechanism to the back of the actuator.
- Use the plastic nut on the opposite site to hold it in place. Tighten it with your hand, don’t use a wrench or you’ll risk cracking the tank.
- Next, connect the flush cable from the dual-flush tower to the back of the dual button unit as required. Tighten the cable tie to secure the new flush valve to the overflow tube and finally reattach the refill tube to the overflow tube.
- In some cases, the old fill valve or refill system comes out incompatible with the new dual flush system and poses an efficiency problem. To counter this, most dual flush conversion kits come with a suitable new fill valve. Remove the old fill valve by loosening the nut located on the underside of the toilet tank and install the new one as per the instructions then make the necessary adjustments
- Turn on the water supply to the tank and test flush first using the low volume flush then the high volume flush and check the water level. If necessary, adjust the new fill valve for optimum performance
Most dual flush systems come with instructions that will show you how to make the necessary adjustments to maximize your water savings.
There are many models and designs of dual flush conversion kits all that serve the same purpose but in different ways. They differ from one manufacturing company thus coming in different designs and some having different or Extra features.

Before you go shopping for the best dual flush conversion kit, there are a few things to consider.
This is to ensure that you get the best product that meets your needs while also being effective. Make sure to consider each factor to avoid purchasing something that isn’t right for you.
While some people prefer the button system for its sassiness and aesthetics, others, mostly the elderly, prefer the handle system because it is more convenient and easy to use. We agree that the handle system is comfortable, but we disagree that it is the most convenient.
Because the button system, while requiring a little more pressure, lasts longer, whereas the handle systems are more vulnerable and appear to be less expensive. You must choose the appropriate type based on your preferences. If you prioritize comfort over durability, the lever system may be the best option for you.
Caliber of flushing
The main reason for installing these kits is to save water or to save energy. What’s the point of getting a kit if it doesn’t flush properly and requires multiple flushes to dissolve everything? As a result, you must ensure that the flushing power is sufficient.
Compatibility and suitability
Is the type of kit you’re thinking of getting compatible with your toilet? Is it compatible with your current washroom setup? Do you require a one-piece or two-piece toilet kit? What is the tank’s maximum capacity? What about the flushing access? These are the kinds of questions we should ask ourselves to figure out if we’re compatible.
Replacement parts and warranty
Check to see if the company offers any warranties and how long they last. You should also see if they provide replacement parts, as there may come a time when your kit will malfunction or break.
Leakage is a common problem that can occur. In these situations, you’ll need to replace the affected parts, and accessibility is critical. Remember, you’re not trying to replace the entire kit, just the damaged parts.
You’ll need enough room to install the kit because it requires clearance. From the inside, 10″-12″ clearance is required for the majority of the tank. Also, look into the space requirements for the system you’re buying
Isn’t it true that we all enjoy getting freebies and bonuses? Plus, if a product has extra features, it stands out and is more desirable.
Look for some extras to round out your outfit. Some products include all of the tools required for assembly.
It’s more about your comfort and adaptability in this case. You must ensure that the button or handles are accessible to the user. In addition, the type of washroom you have must be compatible with the rest of the system.
Some people prefer the buttons to be on the top, while others prefer them to be in the middle, and still others prefer them to be on the left or right. There are also dual-flush conversion kits available, which allow for left-right orientation in addition to the standard one.
