The Impuls360 valves in my toilet set were sinstalled 2 years ago and have been a constant source of frustration ever since. It seems the maker has designed the most complex valve set known to man and kept the manuals on how to service it for himself. My set leaks continually, sometimes by overflowing and at other times by emptying the tank. I need to adjust the height of the overflow but can find no way to do so. The instruction pamphlets I have were obviousy intended for people who do not need instruction pamphlets. Can anyone out there tell me how to adjust the hight of the overflow?
