I am going to add a second breather to the holding tank to try and get some more air/oxygen into it to reduce the killer smell coming out the single vent when we flush.
It will be in the side of the hull, well above the water line, roughly half way between the water line and the gunnel. The hull is solid glass.
Question: Once I have drilled the hole with a hole cutter, is there anything I need to do to the hole before installing the fitting and sealing it with Sika?
BTW, the second breather will be fairly close to the existing one. I intend fitting a small scoop over one of them (facing away from the bow) the idea being to set up a small amount of suction which will hopefully draw air into the tank via the other breather, or act as a scoop if the wind is blowing the other way.
