Are the dual flush conversion parts as good as the parts in a regular toilet?
Actually, the kit we install is of a higher quality than the parts found in regular toilets. The chain and flap technology in old toilets have not changed in many years. Those parts can wear out causing toilets to run and waste water. Our high quality valves are used throughout the world (same as the ones used in new, expensive dual-flush toilets). They are designed and tested to work in less than desireable conditions including silty recycled grey-water, as well as too little or too much water pressure.
