Comments

Barry O: I installed this yesterday afternoon. The instructions are decent. This came with the adapter for an angled flapper seat. ( not sure what it’s called). This adapter has a putty seal around it. I noticed it wasn’t evenly placed on the bottom of the part. Spent a few minutes massaging it into place to get a good seal. Pressed it in place and continued installing. The handle is designed to move up for half flush and down for full flush. When you insert the handle in the tank, make sure it moves both ways. If it doesn’t, pull it out and rotate the part that fits into the tank a quarter turn and try again. If you take your time and read the directions it’s a pretty easy upgrade for your toilet.

Sidney M. Schwarz: Sometimes it gets stuck and the tank does not fill

Turtleshellboy: I've bought these same products before for my previous house and they worked great for many years. They've made some improvements to design. They do save you on your water bill if you adjust them correctly as per directions. So given my positive history with this company and product, I bought 2 more units to install in our new house.

Mike Hamby: replaced an earlier model (that started leaking ) this unit has less connections to auxiliary flush water than the model before - new unit is leak free.

Kevin Campbell: Easy to install and set up. Minimal adjustments required. My only complaint is the length of the handle because to do a half flush I have to lift the lid on the toilet. Otherwise better than my previous dual flush converter.

Joel Tristán: En el primer sanitario que lo quise instalar resulta que no es compatible con la válvula de descarga, así que desarmé el del segundo sanitario y por suerte es de la misma marca que éste repuesto, el resto fue seguir las instrucciones del folleto que viene adjunto.

Anonymous: Bought since previous home owner was using this for their toilets and the lever broke and some minor leak due to the paste wear. Lever broke internally and is made of plastic so no wonder there. There are no direct way that I found to replace the lever since the components are different from the standard flush brands. Seems kind of ridiculous that you have to replace the whole thing for only a lever. However, it is very easy to install and replace if you do have any issues replace in the future.

Paul: Was easy to install, works well. The handle is a little flimsy. Good way to save on water.

Brian K. Reynolds: Installation was a breeze. I spent 10 minutes skimming over the instructions, and probably 30 minutes for installation and adjustment. Adjustment takes the longest amount of time, because you have to keep flushing the toilet and waiting for it to refill before testing the next adjustment.

I don't understand why some reviewers said that it took them so long to read the instructions and install the unit. I have lots of experience with replacing toilet fill valves and such, so maybe it was easier for me than it was for some people.

As one reviewer mentioned, you have to make sure that you get the most current version of this product. I chose the lowest priced option with free Prime shipping, and the product came from the seller named "Innovative Retail Market". I received the old version of the product from this seller, so I cannot recommend them. Fluid Master happily replaced it with the newer model 550DFRK-1 (the -1 indicates that it is the newer version).

I used my water meter to measure how much water my toilet used before I installed this unit. It used 1.9 gallons per flush (gpf). This is slightly more than the rated 1.6gpf printed on the toilet. I suspect...
