I have a Marlon 1-1/2in valve that is verry difficult to turn. The valve has been removed cleaned and greased as recommended by Forespar. All to no avail. The valve is just as stiff.
The setup is thus; thru hull
, Marion valve screwed on (about 1/4in space to the hull
not bolted) then a 90deg elbow
and then to a manual holding tank
I would like to change the valve to something less stiff.
A new maroon valve at $140 is almost as stiff.
I looked at a standard schedule 40 pluming valve at $15 that turns much easier. This valve also has a nut on it which enables you to adjust the tension on the ball.
The new setup would be; thru hull
90deg elbow plumbing
valve fastened to the hull
then to the pump.
Is there any sound reason for not using the plumbing
