Yes.Will a LPR also help prevent a tank dump?
the cost of refilling will probably be very close,I'm thinking for a 10lbs maybe 20lbs.
When, what pressure, do you begin to need to use a LPR?QUOTE]
I had Rex design my system and because I have one of my tanks in the next room he advised me to put the LPR near the furthest tank. From what I understand this is probably the only reason to have one. Correct me if I am wrong.
You always have to buy the first cylinder, whether you plan on doing an exchange or a refill. I wouldn't bother to invest in a shiny fancy aluminum cylinder, but that's just me. I recommend going with the exchange. If you buy/refill, you're responsible for hydrotesting and recertification. If you exchange, it's the company that supplied the cylinder's problem. Eventually you'll have to replace the cylinder anyway. The DOT is currently getting legislation passed to institute a maximum life span for all refillable compressed gas cylinders.Some more thoughts.... buying a NEW cylinder can be expensive (roughly $50 for a NEW Alluminum 5lb). You also want to find out who fills co2 in your area. Some shops offer EXCHANGE ONLY and buying a NEW cylinder would be a waste of money. If you want a shinny cylinder everytime and can/want to fork out the $$$, then you will need to find a place that will FILL ONLY and not EXCHANGE. If you do decide to purchase used/refurbished, then consider the weight difference of a steel cylinder vs. an alluminum.
