1. The nature of the zigzag stitch allows the thread to stretch with the fabric. Turn the hem up the desired amount, then use a zigzag stitch to secure it. A narrow zigzag stitch is less noticeable.Again, this stitch is most successful if you stabilize the fabric and use a walking foot..

Because the leathers will resist pulling back up, it is recommended that you not use PVC pipe for drop pipe. This 2 packer is used in a 2 well to pump from depths deeper than a shallow well ejector can pump from.When using a 2 packer with a VS vertical jet pump, use 1-1/4 drop pipe to allow as much flow as possible so as to not starve the jet pump.ecause the leathers will resist pulling back up, it is recommended that you not use PVC pipe for drop pipe. This 2 packer is used in a 2 well to pump from depths deeper than a shallow well ejector can pump from.
The jet nozzle and venturi are alsoknown as ejectors/ejector kits.On a shallow-well jet pump the ejector kit(jet nozzle and venturi) is located in thepump housing in front of the impeller.A portion of the suction water is recircu-lated through the ejector with the rest go-ing to the pressure tank.hallowwell installations go down to a water depth of about 25 feet. Deep wells are down 150 feetto water, where surface pumps are involved.The jet pump is a centrifugal pump with one or more impeller and diffuser with the additionof a jet ejector. A JET EJECTOR consists of a matched nozzle and venturi.
