I have 2 American Standard Cadet elongated right heights about 5 yrs old. One flushes fine (except w/large load) the other flushes fine 3-4 times then just swirls the water and level never drops 3-4 times
I switched the tanks between the two, bad bowl still bad. I switched the entire toilets between bathrooms, bad bowl still bad. I can pour 10 cups of water in the bowl and it flushes fast and strong. I cleaned the holes in bowl w/coat hanger and poured a gallon of muriatic acid through the tank hole and let it sit in the bowl for an hour. Test it, flushes great, hey honey its fixed! She tries it, won't even lower water level in an empty bowl. A few times flushes fine, then nothing. Time for a sledge hammer?
