Toilet: Rumbling / Vibrating Noise when FILLING up (SMOOTH when flush)
When flushing the toilet, no problem, smooth flush like all others, no issues. (My 1st inclination of the noise when filling up was a clogged toilet, but it flushes quickly and no problems.) **** Issue is when water is filling back up, a LOAD VIBRATING NOISE as the water fills up. fills up fine, but what causes the load vibration?
