Re: propane regulator making noise?!?!
I can only speak for Victor regulators, which can go under a few different names and be the same exact torch except that it is in a different box. Those that we sell come with a 2 year guarentee. If you purchased your regulator new and have had it for under 2 years, call up the company that you purchased it and explain what is happening and you might get a new one in exchange. If there is no refund or exchange available, it would probably be best to purchase a new one rather than fixing the bad one, the only exception I would see is if you had a 2 stage regulator. Since this style is more expensive, it might be worth fixing.
TRUE STORY: This is not an urban myth, this really happend to me.
Regulators do fail right out of the box, others can fail a few days or weeks later, and many will fail if you do not operate them properly. We had sent a new regulator to a customer, who attached it to his/her tank and it was not holding pressure, it was fluctuating and this customer called Frantz Art Glass and told us what was going on. We told this customer to pack it up in a box and we would call tag the regulator back. So this customer packs it up and sets it down on a ledge, but it accidently fell from the second floor. When the regulator was retrieved, it was a total loss. I told our customer to send it back and I would see what I could do, in the meantime we shipped them a new regulator. When I called manufacturer, explained what had happened and the only question I was asked was "was the regulator not working properly before it was dropped?" I told the service rep that the regulator was faulty and that it was accidently dropped and the rep said "no problem". This is what I call great customer service!
