The installation of most dual flush converters is complex, requires tools, and usually the toilet tank needs to be unbolted. We love the HydroRight because installation is simple, tools are not needed, and removal of the tank is not necessary.

Based on dual flush technology that has been used in Europe and Australia for decades, the award-winning HydroRight quickly and easily turns standard toilets into two-button fixtures that have been proven to reduce water usage by 30%. One button is the Quick Flush setting that uses significantly lower water volumes (70% less) for liquids and paper – the setting needed 4 out of 5 times. The second Full Flush button uses the normal amount of water for solids.

Features and Benefits

  • Uses up to 70% less water for liquids, and 30% average overall.
  • Installs without tools in 5–10 minutes
  • Tank removal not required
  • Works with all standard flush valves
  • Eliminates flapper problems
  • Eliminates the most common problems in toilets - the flapper, chain and handle

Please note that because dual flush converters do not fit in every toilet, here are the exceptions you should know about before you buy:

  • If you have a Mansfield toilet, you will also have to purchase a standard flush valve.
  • Your toilet tank must have at least 10-Inch height clearance (distance from where the flapper currently seats to lid bottom must be 10-Inch or more) for the HydroRight to fit and work.
  • The HydroRight replaces only standard size flappers, the flush opening from tank to bowl should be 2-Inch to 2-1/2-Inch in diameter(this is the hole the flapper covers: some newer toilets have 3-Inch flush opening, HydroRight does not work in 3-Inch flush or larger toilets).
  • If the HydroRight is installed in a toilet with an old ballcock, the arm of the ballcock may hit the HydroRight and not work properly. In some cases, the HydroRight can be turned to compensate. In other cases, purchasing a HydroClean or other pilot style fill valve may be required.

Good saving, easy install

By Michael on 2/22/12

All my reviews  (1)

Just like the product says, I was able to install this without any tools. It took me about 10 minutes to install and maybe another 10 minutes to adjust the way I wanted it. Works great. Nice product.

Even a novice can do it!

I admit, I was very, very clumsy when trying to install the HydroRight unit in my bathroom. I have never done anything more advanced than cleaning my bathroom, let alone any sort of repair or installation of ANY kind. Every website I saw, they said HydroRight was the best of the best, so I listened. I read the instructions, watched how-to videos on YouTube, and go to work. It really was easier than I had expected, and everything the company touts is true: no tank removal, no special fancy tools, can install in just a few minutes (first one took me 18, second one took me 11). KUDOS to MJSI for creating a fantastic product!

Great product, easy install

By Brad on 9/28/10

All my reviews  (1)

As a contractor, I do a lot of bathroom remodel projects. In most of my projects, I install MJSI toilet products to help save water and money for my clients. The HydroRight works great to save a lot of water when flushing just liquids. With no tools required to install the kit, anyone can install this kit.

Great for saving money!

By Andy on 9/9/10

All my reviews  (1)

I have installed MJSI HydroRight dual flush kit into my older toilet and it works great. Installation was easy, no tools needed. Some minor water level adjustments and 10 minutes after you start, you're done. Knowing that we are conserving water is awesome and the savings in the water bill is good too! I highly recommend MJSI toilet products!
