Installed this valve and 6 others this past weekend. Very happy with the product and installation instructions. Boat splashed Tuesday with zero issues. I am sold on TruDesign's marine valves. Customer support at GemLux was excellent.
It turned up as expected and complete
Came on time
Very solid construction and operation is smooth and easy. Only drawback is they are kind of bulky so double check clearance if you are going to install multiples near each other.
