Danco HydroRight Dual Flush Converter Review

danco hydroright dual flush converterLast Updated on April 13, 2021 Today we’re going to review the Danco HydroRight dual flush converter as one of the premier dual flush converters on the market.

Dual flush converters are becoming very popular in today’s world of toilet modernization and the idea is that they are meant to replace traditional toilet fill valves.  Because you can save money on your flushes while also being environmentally conscious, it’s an easy decision.

That being said, many people still DON’T convert their toilets to save water and money.  You can see evidence of that in our infographic which shows how little people are still using these inventions.

You don’t have to be a handyman or woman and you won’t need a massive supply of tools.  All you will need is a bit of elbow grease and some time.

This review will look at a few different areas when making a decision on any particular product, specifically this dual flush converter.


  • Saves Money
  • Saves Water
  • Inexpensive Upgrade
  • Leak detection


  • Challenging install
  • May not fit all toilets
  • Fits up to 2.5″ flush valves

Price and Savings

Buying a toilet will be expensive.  There are no two ways about it.  Any good toilet is going to cost you over $100 or $200 and that’s just to buy it.  Installation costs and other costs can easily turn a $200 or $300 toilet into a $400 or $500 purchase.  Unless you want to do it yourself, which is a completely different situation.

Rather than break the bank on a brand-new toilet, you can purchase a dual flush converter.  This option is not only cheaper than a brand new toilet, it will actually put more money in your pocket with its savings. An independent study found that the HydroRight showed average water savings of 30 percent.  Which means you’re saving yourself at least $100 a year or halfway to a brand new toilet whichever you prefer.

That means by simply using the HydroRight dual flush converter for more than 2 or 3 years you will save yourself hundreds of dollars on your water bill.

The environmental price also has a lot in savings.  By Saving 30% of your water bill you are in fact saving 30% of your water consumption.  This leave some for everyone including the fishes.  The HydroRight dual flush converter can save thousands of gallons of water per year per household for costs most people would never imagined 25 years ago.


We noticed that with the Danco HydroRight dual flush converter that the installation sounded easy in theory but not so much in practice.  It was challenging to drop in this dual flush converter even though it is sold as simply being a drop-in converter.

Be sure to stay focused on the silicone gasket and make sure it fits flush.  It was no easy task and was initially leaking at first, prior to us getting everything settled in properly.

Older toilets might also have trouble with the HydroRight dual flush converter.  If you have a ball float flushing mechanism, you may need to look into a conversion kit as opposed to a drop-in converter like this.

Everything you need to install this comes with.  We still didn’t use any external tools which makes this a DIY project that’s easy for any individual regardless of their tool setup. But it was challenging none the less so be prepared to encounter some difficulties.


The HydroRight converter is very durable once it was installed.  We installed it on a 2-inch fill valve which is recommended for this dual flush converter. It was snug and it wasn’t shaky in any way.

A quick side note, it can also fit a 2.5 inch fill valve if you need to (this is not recommended) but cannot fit a 3 inch valve.  That makes sense anyway, right?  This is for 2 inch valves only.

Bonus Feature

This converter can also check if you have any type of leak in your toilet.  Danco utilizes patented technology to measure the tank water at various points over the course of an hour to understand if you have a leak.

You can see how this process works in this video. You engage the float lock in the off position, and then leave the toilet alone for an hour. If when you return the tank water has dropped then you have a flapper leak and it’s as easy as that to figure out.


The Danco HydroRight dual flush converter does come with a 5-year warranty too, saving some stress when thinking about order.

Final Thoughts

Of all the dual flush converters on the market, we are big fans of the Danco HydroRight.  It is cost-effective and has a proven track record of success in the realm of dual flush converters.  There are a number of “quick fix” type converters that should be avoided when making a decision like this.  You want strong and durable, not a gimmicky item you saw on TV.

Our main reservations are of course the installation process but in the end it was viewed more as a sign of strength.  Not necessarily a negative that would stop us from picking up again in the future.
