HydroRight Drop-in Dual Flush Converter $15.30 + Shipping
 

We had a thread about this a while back - the dual flush conversion. If you guys are interested, Amazon has them cheap right now. I bought one several months ago and have been pleased with it.

The listed price is $17.64 but it will drop to $15.30 after you put it in your cart. Happy flushing!

Wow, that is a great deal. I think I paid ~$25 for mine.

I think mine was also about the same price. I found out that they don't work on the 1.6 gallon American Standard toilets because the overflow tube and flushing assembly is one piece and to remove the flushing tube would also remove the overflow tube so I would have to swap my toilet to use it. I since found out that I can use a crafty light touch for a moment and get the toilet to flush with less than a gallon anyway so mine is still in the box since the toilet downstairs will never be used and I'd have to swap the arm float to one of the compact models to use this. So basically I won't save any water with mine so its in the box still.

So if you get it, you will probably have to buy a toilet valve that doesn't have the arm and ball and it won't work if the overflow tube isn't separate from the flush tube/hole.

Just looked on Homedepot's website they sell this as well for $17.98 says it's also sold in store. Just a heads up if you want it quicker
