CamcoCyclone Sewer Vent Cover | Draw Holding Tank Odors out of the RV, Trailer, or Camper | Black (40597)

This product is an absolute must. Easy to install. Right after I installed it. It was working immediately. Within an hour my black tank smells were gone.

Easy to install. Does the job as intended.

So far it has rotated with wind and while driving and has cut down on the sewer smell while flushing the toilet.

This thing did nothing at all and there’s been wind every day. The smell continues. I did get a badly cut hand trying to remove the putty from the original vent cap though that took 4 stitches to fix. Update—- I have since writing this review found out that the smell were having a problem with was caused by the cheep plastic toilet my motor home came with not from the black tank. I replaced it with a nice porcelain one and now it’s gone. The vent is working fine, no odor coming up at all. The only issue with the vent is that it is open to critters. Some of the other styles have built in screens. I will install a screen in the opening to solve that, not a difficult task.

I don’t know why these don’t come standard on all rv’s. Removed old vent and ran a water hose to wash out vent stack thoroughly after watching a video that suggested it. So glad we did because it was stopped up from previous owner and not venting properly. Do not let your tank over fill. Installed the cyclone once everything was cleaned and it worked immediately. It’s the best rv hack item we have ever bought! Why haven’t you put it in your cart yet?

Works exactly like it's supposed too. Extremely pleased with this. Best $ I've spent this year. Easy to install too

This unit really does the job! Normally we get terrible sewer odors in our camper when driving down the road or parked in the wind. Apparently we don't have enough vents or in the right place or whatever. I installed this over an existing pipe, but had to cut the pipe down because it was near the ladder and I had to make it low enough to make the fin clear the ladder. I also shaved a notch in the fin so it could swing past the ladder handle freely. It also doubles as a wind direction indicator.We drove down the Alcan to Montana and back with this baby installed and not one single incident of sewer gas, even in the heat of summer. If it ever breaks another one is going on in its place. I never knew the fix for that stink could be so simple. When we are parked it always aligns itself with the breeze to keep the vent flowing the right way. Very nice!My only worry is our habit of bushwhacking. We have to be extra careful to not catch it on a low hanging tree.It has been on the camper almost a year and still swivels freely in the slightest breeze. It has survived the Alaska winter without breaking spinning around in the cold. We finally drilled a hole in the fin and tied it to the ladder rail to keep it from getting unnecessary wear during windy days.*******************************Update August 2017. 3 years and 2 Alcan trips and this vent top is still spinning in the wind and keeping the camper odor free. I thought the plastic might give out on some cold winter, but it is holding in there and it still turns freely. We have gone through brush and low tree limbs without tearing it off, but the ladder protects it some and we try to keep out of the harder branches. I well made product. Hope they don't change to something cheaper when we finally need a new one.

I found this to be an easy upgrade on the RV. Product is made well, easy to install, and works as designed!
