After a gruesome visit to home depot and back home only to find that I had purchased the wrong item I was hopeless. I decided to take a picture of the toilet tank unit I needed in order to get the same one and swap it out. I went back out to Home Depot once again only to be advised by a Home Depot employee that this defferent looking mechanism would work. I went back home and of course it did not work.
I decided to visit Ace as a last resort. It was the only place that had a Mansfield tank unit which I decided to buy the three they had since the three toilets in my home have this model in them. The item was very reasonable priced and saved my any further anguish. I was so thankfull to find this item and to not have to order it online and did not have to pay for shipping or wait a week with a broken toilet.
I was so exhausted after all of the running around I was not willing to go back another time to return the wrong part i bought at Home Depot. I think I lost enough time already. I will go to Ace Hardware first. I will not be running around again.
