Vent Pipe Over Bathroom On Roof

by kathy oleson

Question: I have awful smells in RV white cap on roof looks like i hit it with a hammer.I can see the black pipe coming up middle.there is nothing in the pipe but it is loose.the white vent cap(around)black pipe is shoved down 'bout3-4". What can I do ?

Robbie: The pipe being loose in the hole is normal. It is a vent pipe from the holding tank. The odor you are getting is probably coming down the side of the pipe and into your RV. If the old Stink vent cover is all but gone leave what is there and seal around the pipe with Silicone or Dycor roof sealer. Then install a new "Stink Vent" over the pipe. When you purchase the new vent cover look at all your options, you will find many different styles. I suggest you have a sales person show them to you and get one that uses the wind to pull the odor away from the pipe.
