Hello all. I'm finding that I'm having to hold down the lever long to get the toilet to actually flush now. It has gotten worse over the last month or so. Also, I'm not sure if this plays a part, but the refill tube keeps coming out of the overflow tube and into the tank. It doesn't seem to want to stay in the tube. My bowl fills up with water, (not as high with the tube not in the overflow tube) but just a quick press and release of the lever does not flush the toilet anymore. I'm having to hold it down a bit to get it to actually pull the water from the bowl. Also, not sure if THIS has anything to do with it, but my son may have flushed a couple of paper towels down the bowl a week ago. They went down, but I thought I'd mention it. Do I just need a new flapper or fill valve? Can I provide you with more info to help diagnose? Thanks in advance!
