I had trouble identifying the correct tubes for my toilet, and NuFlush's customer service helped me sort it out with outstanding customer service. I called them, they listened and discussed the problem with me, and help me get everything sorted. I would purchase another product from them without question.

These are such a good idea ! I had all my toilets replaced and they put in these low water flushing systems which didn’t use enough water, Once I found out I could increase the water in the tank with a higher overflow tubes my toilet problems were over ! These are simple and genius!!

Save your money and buy replacement fill tubes. This pack comes with all different sizes but since a full tube only costs $7 then this is a total waste. You get a seven pack but can only use one if all of your toilets use the same size. Don't bother. I'm returning mine.
