We have 2 baths upstairs and they are back to back. One is for the daughter and one is our master bath. Lately, when either toilet is flushed it continuously runs, to the point of me running upstairs to lift the toilet tank lid and tap the "arm" of the chain to stop it from running. I'm not resting during the night cause I hear water running - drives me crazy - I have to go do the "toilet tap" to stop the running. Our quarter billing for our water bill went up $200 since this toilet issue. DH went and bought a new flap. He said "toilet's all fixed!" 1/2 hour later I hear water running and I have to run upstairs and tap the dern arm. Am I missing something? Is there another remedy for this type of problem? I did shorten the chain on one toilet. Nothing's changed. Still running after it's flushed. And the weird part - I'll fix the arm for the moment and go do something and it starts running again and no one was in there. Is it time for the whole new guts for the toilet tank? Or is there another remedy? Here's an interesting side note: When i go into the kitchen and turn on the water the spray nozzle (while resting in it's spot) sprays water at me! I didn't touch the nozzle! So i took it apart and cleaned it up and put the spring and washer and everything back together and tightened the nozzle. Everything's fine. for a few days. First thing this morning - turn water on in kitchen sink to make coffee - BLAST of water right at me! The spray nozzle! No coffee needed - I'm awake now! But the toilet issue really pisses me off. Any home remedy hints I may be missing? Any help would be appreciated!
