Changing out black and gray dump valves.
From this angle, the gray tank is on the left.
The tanks are solidly mounted. Had to pry the flanges apart to get the valve out. The gray tank is on the right in this shot.
Used the two of the mounting bolts in opposite corners to spread the flanges apart. When the gap was wide enough, inserted the valve. As the two bolts were removed, I kept checking the valve for no binding between the flanges.
Both valves were replaced. The inages is showing the gray tank.
Note: When the flanges were spread apart to insert the valve, the space between the flanges was about 1 1/4 inches. The corners were showing signs of bending and flexing (they did not break or crack). Also, the additional clearance was created by the black and gray tanks bending/flexing in. On the black tank a crack did show up after water testing both tanks. JB Weld for plastic fixed the crack.
Job tested and complete.
