UPDATE (Dec 2011): At Home Depot today I saw an end cap with an infomercial running about this gizmo. However, I took one out of the box, and I was so disappointed to see the same darn paper-thin gasket that I (and many others) have reported to them over the past 2 years. Additionally, the Home Depot staff said they get a lot of returns on this item. This company knows that their gasket is too thin, causes leaks, and that including a higher grade gasket would cost them very little (approx 20¢ per unit). Somehow they can find the budget to launch a Home Depot marketing campaign & produce a new infomercial, but can't spend an extra 20¢ per product to prevent the headaches they're causing. I'll add that my fixes work, but the silicone seal is NOT a permanent solution (already had to replace it once). If this gizmo is not ready to use out-of-the-box, and requires annual or semi-annual maintenance, it is NOT ready for the market. If you want a dual flush, you can get a brand new dual-flush toilet for under $100. Original Review: ====== Ok, I also had two problems when installing this, and I have fixes for the 30+ people who have complained about similar install problems (same root problem in almost every instance). I predict that for MOST people, this dual flush device will not be an "out-of-the box" solution - you will need some troubleshooting not included in the instructions. But I also predict that because of bad installs, some folks here (not realizing it yet) will have running toilets, or will actually use MORE water on the low-flush feature than they did before! Unless you measure it like I did, you'll never know. This is a SERIOUS problem this company needs to address, costing lots of money and wasted water - and homeowners may never even know it! I feel ~really~ bad for the folks who spent hours & hours wrestling with this device, but I promise these 5-minute fixes will work. I wholeheartedly agree that there are design flaws here, but finding a workaround saved me the hassle of returning it & messing around with another brand (and probably an entirely new set of problems). I'm going to stress - you CAN get this to work with your older toilet, and you do NOT need the HydroClean (or any other) device to make this work. I like the HydroClean unit, but IT IS NOT NECESSARY to install your dual flush converter. FIRST: THE LOW-FLUSH FEATURE ISN'T WORKING FOR YOU Again, I totally agree - the instructions aren't clear. I had to try 20-30 flushes before my "Ah-ha" moment. If your low-flush doesn't work, 99% chance the problem is water level is too low. It's not getting enough water to flush. Do NOT hold down the flush button to get this to work - if you have to do that, it that means you're using more water than before! And do NOT flush twice To "fix" the problem - just read on... Solution (bottom line): You need to set the float level for the low-flush (the blue tab) 1/2" BELOW where you want the water line (yes, below). Then, the water line has to be about 2" ABOVE the float, so it can use roughly 2" of water on a low flush. I know it sounds odd, but try a flush - if it doesn't work, keep adjusting the low-flush water level up a notch. I PROMISE - this will work. I know it sounds backwards - but to save water you will need to keep MORE water in your tank. The water is not actually used each flush - it just needs 1.5" to 2", which should translate to .6 gallons or less. (My low-flush setting uses .4 gallons, which is efficient and also 33% less water than national standards for even a urinal). If you have a HydroClean installed, it may actually be getting in your way. So set the float/fill level to the near maximum setting. With my HydroClean, my previous setting was about 1.1 gallons with my toilet (I thought I was saving water this way). But with the dual converter installed, I had to add nearly 50% more water to the tank - so that the low-flush feature can work right. Now my main flush uses 1.2 gals (about 25% less water than national standards), and my low-flush works great too. SECOND: YOUR TOILET IS RUNNING Some people may not even realize that their new dual flush converter is running. A running toilet will definitely waste more water than it saves - possibly wasting hundreds or thousands of gallons a month!!! The problem is the blue "silicone" flapper gasket is CHEAP thin rubber. If it's not perfectly straight, the rubber will fold or ripple & allow water to seep into the tank. Frankly, I would suspect 75% of all users will immediately or eventually experience this. It's a bad design, almost a defect (it needs to be larger & sturdier). I had to refit this 3 or 4 times, but the problem is, once the entire dual-flush contraption is fully installed, you can't see the blue gasket to confirm it makes a good seal. You MUST listen to the toilet a few hours after install, to see if it runs (or add a blue cleaning disc or some food coloring to your tank, then check the color of the bowl later). This can waste 10-100 gallons per DAY (yes, up to 100 gallons) - so if your goal in using the dual flush is to save water, think twice. Solution (bottom line): You will most likely need to seal it with a waterproof silicone sealant or high-grade waterproof caulk. A third potential problem is replacing your flush handle with the new dual-flush "button". If your handle is off to the side of your toilet tank, if you have a triangle-shaped toilet, or if your toilet is right against the wall, then you (or your guests) won't be able to see which button to push. I give this 5 stars for ingenuity, but 1 star for major design flaws.
