Removing shelf under bathroom sink for plumbing access.

Hello all, 

do you simply pry these white caps off?

I am getting some resistance, so I wanted to make sure before I go to town on them. 
thanks

Hello Marc,

Yes. There is a phillips screw head under that plastic cap.  A gentle but firm pry should pop them off. I think I used a plastic putty knife but a small standard screwdriver should work, being carefull not to damage the fiberglass.  

You will also have to carefully break (slice) the bead of silicone caulk around the edge of the access panel to remove it.  A new sharp plastic razor blade should work without damaging the fiberglass.

Suggest adding your Hull number to your posts so folks know what year your trailer/equipment is.

Hope that helps

Thanks, 

I wasn’t able to figure out how to add my hull # to my signature, but it’s 2024 hull 1502. 
I got it off and cleaned up. 
is this a vent stack or anti siphon setup?

I figured it out

It’s the backflow/ siphon break for the black tank flush
