Pumpkin beer flavored beer lines

[Duck&BarrelBrewing]

Hey all I got a question for you. I have a keezer with taps and I had changed out a keg of my pumpkin ale to a keg of a lager. However, everything tastes like cinnamon and clove.

I did push PBW through the lines and let it soak for an hour. But the flavor is still there. I don't want to have to change the beer lines but I may have to.

Does anyone else have this problem with strong flavoured beer going before a lite beer in their keg system?

I also have food safe PVC vynal tubing so I am wondering if I need the EVA tubing. Here is a link to what I have

And does anyone know of a good line cleaner that will remove the flavor of the previous beer?

I don't. It's been a while since I made a spiced beer, and I don't recall having line trouble after. But I have read that root beer can persist in lines. My fermenting buckets smell of hops regardless of cleaning. Changing the lines might be simplest.

just flush the lines with lots of beer...I know it's a lot to drink but I believe in you...

Pumpkin beer-flavored porous beer lines. Good time to switch to Evabarrier. Only thing I know to clean up after that:

Replace the lines. You can save the old ones until the fall and sell them to those that complain about 'not enough pumpkin' in their pumpkin ales. I think you can make a fortune.

Time to spend a few dollars to get some new EV lines is the easy path.

I've had similar happen when I used cheap Amazon "food safe" no name brand lines before with a raspberry gose. I put a hefeweizen on that line next and could taste the "gose" of beer past. Get it. Gose. Sounds like ghost kind of. Oh never mind.

Just take the advice and replace your lines with EVA
