I have an Rigid ash vacuum and I'm thoroughly disgusted! It blows dust through the top exhaust port after just a few minutes of use. I check the connections and all is secure! There is no more than a coffee cup of ash in the bottom. I even put water in the bottom of the canister and it still comes out? Prior to buying this I used a shop vac with water on the bottom and it worked better. Am I wrong to think that you SHOULD NOT have ash coming through the exhaust or am I just freak'n NUTS??? Any help or suggestions would be appreciated
