VALTERRA WASTE GATE MOUNTING POSITON

UPDATE: The valves will be adequately secured and have enough ground clearance. There should be no problem with valve stability. Just more convenient to mount with handle in down position. I can see a problem with seepage in to handle. Can't find any installation instructions from companies like Valterra.

Don't know what your ground clearance might be, but a handle pointing down could manage to snag something. Might bend or brake something and/or might be creating "a new dump station".

Never seen them mounted down but seems dangerous. If you have to mount them that way, perhaps you can secure them with something.

I think you will find the instructions say to mount facing up or sideways
Down may allow for liquid to creep into the pull shaft area , dry up and bind the shaft
Also easier for the cable to operate pulling and passing side ways, that with a 'U' bend in it

One thought is that it would be more difficult to hand operate them in the down position than to the side.
