5 Best Dual Flush Toilet Conversion Kit Review
To help you make the right pick, here, we’ve reviewed top dual flush conversion kits out there. Read on to know more about them.
1. Next by Danco HYR460 Universal Dual Flush Toilet Conversion Kit
Our first dual flush kit does not only convert your toilet into a more energy-saving one but also is equipped with smart tech made to detect, signal, & eliminate common leak issues related to the toilet flapper. This one is the best dual flush toilet conversion kit for 3.5 gpf toilet in the market. One factor about this kit that users seem to love is how easy it is to install.
Even for a beginner with zero knowledge, the danco hyr460 kit takes about 30 minutes at max to install. No additional tools are required either for installation.
Some users have reported needing to be careful with how long they are holding the handle down as shorter time may lead to insufficient flushing. Not a very large issue though, just hold the handle down for longer to ensure proper flushing.
The smart tech in this kit detects any leakage and signals the user when it finds one. One thing you should watch for with this is ghost flushes – it happens a lot if the seal on the valve seat is not set properly. This is a very fixable issue though, just use some plumber’s putty to seal the valve seat well.
Pros:
- Cheap & easy to install
- Smart tech that detects leaks
- Lasts long if properly installed
- Looks very aesthetically pleasing and will complement your washroom
Cons:
- The coating on the valve adapter is prone to making air pockets
- Is not compatible with Mansfield toilets
2. Next by Danco HYR271T Hydroright Dual Flush Toilet Conversion Kit
My next pick is also by the same company as the previous one, and it’s for good reasons. Danco, one of the biggest plumbing replacement, remodel, & repair suppliers, focuses on do-it-yourself products and makes them well.
The hydroright dual-flush converter fits toilets that are 1.6 to 3.5 or more gpf. It is very similar to the previous one and seems to solve the issues users had with the previous one. This kit is taller so fits toilets with larger seats better, the handle does not get covered up.
You also do not have to be mindful of how long you are holding the handle down with this one. One issue users seem to be having with this dual flush converter is that the half flush function needs some work and effort to adjust. The refill float of this kit needs some adjusting to get it to work flawlessly.
Overall, it flushes really well and can be your ideal dual toilet converter if you manage to get it installed well.
Pros:
- Handle system is easier to use compared to button
- Really efficient with water reservation, up to 70%
- Easy to install
- Has a tight seal and fits well
Cons:
- Only works with side handles
- Half flush system and float may need adjusting
3. Fluidmaster 550DFRK-3 Dual Flush Conversion System
This one is a modern design which fits any 2” flush valve toilet. It is fully adjustable and can fit into almost any kind of toilet you may have.
And the fluidmaster duoflush is more durable than the previous two with an anti-corrosion feature and will last heavy use for years before needing a replacement. However, just like the first kit in the list, this one also creates issues with the flush valve seal as some users reported; it needs replacement after about 6 months in some cases.
Installing this one can be a bit tricky as it takes about 2 hours for beginners, gives, or take. But the instruction manual is very clear and easy to follow so anyone can get it installed with a bit of patience. It also has a troubleshooting guide, which can be helpful in case of difficulties.
In short, this one flushes very well using a low water amount, but you may or may not need to hold the handle a bit longer, depending on your toilet tank design.
Pros:
- Versatile and compatible with a wide range of toilets
- Comes with clear instructions
- Will last a long time
- Has a modern design and will compliment your bathroom decor
Cons:
- Water-saving is a bit less compared to other kits, about 45%
- The handle is cheaply made
4. MJSI HYR270 Hydro Right Dual Flush Converter Kit
The 4th one in our list is made to be very practical as well as stylish – it will save up to 70% water while also giving your washroom a fresh appeal and elegance.
This dual flush converter has a button system as opposed to handles. Just like the first one on the list, it also features a smart tech system that can detect and signal leaks. The button in this one is called a light touch button, meaning it does not need too much pressure to push.
Installation of the HYR270 is very easy and fast; it takes about 10 to 15 minutes only without any tools or tank removal. Seriously, this might be the easiest toilet modification job you will ever do. The seal in this one is very secure and does not create any issues like some of the previous ones do.
To conclude, this one is a really good option that requires less effort tweaking and installing compared to the other ones on this list; and it works really well with old toilets that usually use a lot of water.
Pros:
- Very simple and easy installation
- The seal is very tight and well made
- Replaces junky linkages as well as flappers inside the tank
- Compatible with a good range of toilets except for Mansfield ones
Cons:
- The indicators for single or double flush can be too subtle to notice
- Will wear out after a few years of use
5. FlushSaver Push Button Dual Flush DIY Conversion Kit
The last one on this list is also the priciest one – about $10 more than the rest, but it is still relatively cheap. It is modeled after European style and replaces problematic flapper mechanisms with a dual-action piston as well as columns with seal evacuator. This can be a good option as a dual flush conversion kit for one piece toilet.
Out of all the products on this list, this one has the most positive reviews from people who have actually used it. The only complaint I found was that if you are not careful about flushing properly, a small stream of water may continue releasing after you are done, which is wasteful and defeats the purpose.
That being said, this is more of a user issue than a product issue, so be careful when you are using this.
Another thing worth mentioning is that this is the only kit in this list, which requires the user to completely remove the tank and its parts & then restructuring when installing. But don’t be afraid because the instructions that come with the product are really easy to follow.
Pros:
- Different button sizes indicating small or full flush
- Tight seal that works well; no air pockets or deforming
- Comes with clear instructions for installation
- Fits different types of toilets well
- No reports of ghost flushing
Cons:
- May keep running water after use if the user is not careful
- Needs dissembling and restructuring
Things to Consider Before Buying The Best Dual Flush Toilet Converters
In order to find the right dual flush toilet conversion kit, you’ll need to keep some factors in mind. Below, we’re going to talk about them.
Handle/Button System
Some people, especially the elderly and people with arthritis, may find it easier to use a handle rather than pushing a button. But keep in mind that handles are usually made of plastic and may look cheap compared to buttons.
Flushing Power
If the dual flush conversion kit does not provide you with a strong enough flush, then you may need to flush twice or more – which will defeat the purpose of water-saving.
Space for the Kit
Usually, about 10”–12” empty space inside the toilet tank is enough. Make sure to check the space requirement for the specific model you are planning to get.
Accessibility of Handle and Buttons
You should figure this out based on your washroom setup and the person who is going to be using the toilet the most and their preference – whether you want a center, right, left, top, or side-mounted flush that works for the washroom configuration.
Availability of Replacement Parts
Over time, some parts of the conversion system may get faulty or even break. It is a very normal occurrence. Make sure you can buy replacements of major parts of the model without having to buy a whole new kit – which is wasteful.
Compatibility
Usually, the kits are made to be compatible with almost any kind of toilets; even so, some of the kits may not be flexible enough to use on the type of toilet you own. Do thorough research on things such as tank space, flush opening, overflow tube, etc. before buying one.
Additional Accessories
Some kits contain the tools and plumbing materials you will need to install it, while others do not. Check if there is anything else you need to install the kit when shopping.
