The part arrived in a timely fashion along with two mounting screws. When I tried to install the valve, I discovered that the screws provided did not fit the threaded holes on the part. Neither did the screws for the original part. I had to take the part to a local hardware store to find screws that would fit, then work an evening shift at Target, and finally complete the installation late in the evening. While the valve works beautifully, I should not have had to go to this much trouble to install it.
