The last one I had lasted 20 years I like a good full flush. the modern syphon one save water but you have to flush more times. I was in Canada when I first saw these and I have been hooked on them ever since. Simple and efishient
Push button and siphon flush systems may look nice, but this Fluidmaster flapper valve system is simple and provides the best flush. Is supplied with several different fittings for different lever handles. Good value. Supplied quickly and efficiently.
