I am considering replacing my roof vent caps with the 360 Siphon RV Holding Tank Vent Cap. When I went on my roof I found four (4) vent caps. Is this correct? All I can come up with is that there is one for the kitchen sink/DW, one for the toilet, one for the shower/bath sink, and one at the rear of the coach for the washing machine.
Shows 3 roof vent caps.
Shows 1 roof vent cap at rear of coach. (Washer?)
