roof sewer vent

[CeeDee]

Howdy
we have a 09 30sk 5th. Have 2 sewer vents on the roof ,1 near the tv ant the other on the other side a little further back. My question is which is the black water vent? I want to install a cyclone vent but on the black
thanks Cal

Ours is right above the bathroom area (all-in-one bath).On our Cruiser it was right above the potty room.Edited by: Hunter11

The black tank will be directly or almost directly under the toilet and since the tank is almost the full width of the trailer, the vent will be very near the toilet. It might be on the opposite side of the trailer from the toilet, but it will not be very far forward or rearward from it. Drain lines for the grey water are longer and smaller in diameter, so the vent for the grey tank can be further away from the actual tank placement.

My 30SK is a 2007 but the vent layout is probably the same. The vent next to the batwing antenna is the blackwater vent. It goes down thru the hallway cabinet into the basement and forward into the blackwater tank.

Our CF31QB has the half bath in the master bedroom with its own black tank. There is only one vent on the roof for all tanks. I put a turbo vent up there a couple of weeks ago and searched for another vent but there was but one.

I installed the cyclone vents on all the vent openings on the roof, pretty easy to install, you need ro remove the flange on the roof and all the dicor sealant, when I put mine on I used Etrnabond tape to seal them instead of the dicor, they seem to work, I never had any kind of smell inside bit it was an easy project to do, I installed 3 of them, I was going to do the roof with etrnabond and it was a good time to do them....good luck with the project
