Review on 🚰 Efficient Fluidmaster 703AP4 Fill Valve: Quick and Easy Installation - 1 Pack by Tyson Burch

My Glacier Bay toilet was leaking so I ordered this unit as a replacement but in less than 4 months it is leaking again. Upon inspection, it was found that the (rubber?) shut-off disc ("242 TOILET SEAL REPLACEMENT" according to their website) was slightly broken, making it no longer blocking the flow of water. I was expecting the entire product to last longer, not in direct sunlight and not being able to handle the extreme heat or cold of the San Francisco Bay Area, and only very light home use, and was shocked to see that after 4 Months of use failed.
