Hi All, I'm a novice DIYer in this area who you've helped before so I am hoping you can again. I have an older Mansfield 160 toilet. It has that older style float ball and a very different (to my other flapper Toto toilets) style flush valve. After flushing, and over the course of an hour or two, the water level slowly creeps up to the top of the overfill tube. Usually no obvious sound of dripping/filling (although occasionally it keeps dripping for about 30 sec.) and some very feint hiss for a while immediately after the flush. I'm thinking I need to replace the fill valve. I'm fairly familiar with the Corky 528 fill valves as I've used those in my Toto toilets when the originals failed. My question is can I switch to a 528 (and in the process get rid of the big float ball) or is it better to stick with a Mansfield fill valve for some reason? I know the 528 is supposed to be "universal", and it's easier to source (trip to Lowes) but just wondering if there is any problem with it working with this very different style flush valve. Thanks for any help. -Jim
