Dear Earl,First, if you are using a self cycling system and the pump is coming on every 10 minutes or better, the leak will be so hard to find its not worth it. The sorter the amount of time between pump recycling the easier the leak is to find. A leak that makes the pump cycle every 30 seconds will be much easier to find than one that recycles the pump every 5 minutes. I always start by diconnecting the pump from the bag and testing the pump, just to be sure the leak is not in the pump. Once you have established the leak is not in the pump, I start by turning off all noise in the shop and listening carefully over the surface of the bag. If that does not yeild anything the next thing I do is to take a dye soaked rag and blot it on any suspicious spots, if it is a leak the dye will be drawn through the hole and make a mark on the platen. Also be sure to check the underside of the bag, sometimes an object gets on the table the bag is sitting on and grinds a hole in the underside of the bag. The underside of a bag is rairly checked. Any glue and chips on the area of the bag where the closure goes will cause a leak also, be sure to keep this area of the bag clean.Bottom line on leaks is, they can be very difficult to find sometimes and there is no one easy way to find them.sincerelyDarryl Keil: What is the easiest way to find out where my poly bag is leaking?
