Sink Twice for Toilet Tanks Measuring 15.25″ – 16.8″ (Measured with lid Off) – – Amazon.com

I said that it would reduce your water consumption. I phrased it that way because I don’t know if it will help you to save money. If you pay rent, your water is probably included. BUT money is not the most important thing. We must conserve our resources if we hope to be able to share them. This will help you to do that. If you are not paying rent, this WILL help you to save money.

I’m not a plumber, but I was able to install this by myself. The manufacturer is very helpful and was able and willing to answer a few questions I had. For example, the instructions differentiate between a high pressure toilet and a low pressure toilet. I did not know which I had. I asked Home Depot. They were not able to help. I knew my toilet was low-flow. Did that mean low pressure? Short answer – no. I contacted the manufacturer and he told me that most toilets in the US are high pressure. Mexico and some other countries have low pressure toilets. I just needed to know so that I would follow the right instructions.

Another thing which is helpful. When you detach the original refill tube from the refill valve, keep it. You may find that it is difficult to stabilize the fill cycle diverter over the overflow tube. If so, you can add a segment of the tube that you saved to the bottom of the fill cycle diverter so that it anchors the fill cycle diverter in the overflow tube. I sound like a plumber, don’t I? No, definitely not a plumber.

Good luck! I think you will be happy. I hope to get the manufacturer to customize one for my other toilet which has a rectangular dual flush control in the existing tank top.

One other point which I would like to add now, manufacturer suggests using Method brand sea mineral foam soap which is available from Target. It may be available from other places too. Apparently, some soaps, e.g. organic lavender soap, can contribute to mold growth in tank. We don’t want that. I believe some reviewers have made a complaint on that subject. I’m quite prepared to plot and plan worksarounds 🙂
