wow.. very unfortunate to hear about this as i just ordered an iceburg from exotic pc.. i wish i had found your review before i made my order or i would have selected other options open to me other than the iceburg...
i suppose you possably saved me allot of money for having warned me about this grave defect in advance... i suppose i can salvage the rest of the system for now by ordering a much better made pumptank. it looks like the iceburg uses a 3/8" or .375" inside diameter fittings for all it's components.. i suppose i go on that for now and find out what is compatable.. (pefferably copper construction)..
