Guys be very careful when you are removing and re-installing the drain valve. If you get one of the screws over tightened or cross threaded, you 'll end up having to take the bowl assembly off and re-tapping or in my case having to buy a new bowl. My original valve lasted over 100k, the 3 valves I've had since then have only lasted about 20k each. When I screwed it up it was cold a drizzly while changing it outside at work, guess I got in a hurry and messed it up. I still carry a spare valve in my truck due to them going bad so easily lately.
