I am in the process of purchasing a new house that has a pull chain toilet. It is well water with city sewage. I really like the overhead tank pull chain style toilets as I had on in my house as a kid. I also have always wanted to be environmentally conscious and liked the idea of the dual flush toilets that have two flushes one is full tank the other is partial tank so you can choose which flush to use based on the type of waste you deposited.
Since there are many dual flush converters for most toilets I was wondering if there were any conversion kits to convert a pull chain style toilet to a dual flush one. Perhaps with two chains? Would a normal conversion kit allow this with some DIY modifications?
