RE: Problem w/ my new pump jamming.....
Make sure to ask them to pick up the shipping costs too.
I had a problem with a new scope once, and although theyagreed to fix it for free they did not volunteer to pay for the shipping. They did end up paying for it, but I had to ask. They weren't going to just give it to me if I didn't already think I was entitled to it.
Give it a try. Can't hurt, but might help.
