Thread: Badger 150 pulsating problem

I bought a Badger 150 used and have a pulsating problem. Talked to tech support at Badger they said the teflon seal was the problem. Bought a new seal, and needle bearing and tip still pulstating. Decided to try the cup instead of the bottle and pulsating went away. Went back to the bottle pulsating came back. Doesn't pulsate with the cup only with the bottle what is the problem.
