Hi, another question about a HH mine is whenever I go to light it it will light but then there will not be enough pressure for it to stay lit. I have hung the hose to clean the gunk out and taken the top part off and cleaned that. Is it the tank. I just got another full bulk tank and have used it twice and had trouble each time but usually I can get it to stay on with enough pressure. Is it my tank or my HH? Do I take it back and ask for another one? Will I have to pay it is still partially full. Only used twice for probaly one hour each time. I'm getting a little ticked off b/c I'm not getting anything done. Thanks for any comments.
