I'm replacing my toilet handle for the second time in three years. That makes 3 handles in three years including the original.
I think my father rarely had to do that. I bet toilets made from the 50's -the 1970's had handles that mostly lasted as long as you had the toilet. Chances are you updated the home and tossed the old crapper out. With all working parts.
Now? Its plastic where metal should be. Plastic threads on a handle is muy malo. Something set to twist that often needs to be metal.
Uhg,Now I think the float valve is wearing out.
Damn them cheapo manufacturers and Home Depot for even carrying parts they KNOW are below standards. IF Home Depot had standards themselves.
