[QUOTE="penfooey, post: 241956, member: 1654"] Hi Barry. We used about 100 mil of black rubber pipe insulation at the end of the plunger, tied on using small cable ties. The plunger is DN20 and the outer is DN40 white PVC with caps and joiners to suit. We are looking to replace the black rubber with plumbers test plugs which look like they would do a better job. Have to get these on the internet as we couldn't find them anywhere..well the size we need is not readily available. Will let you know how they go. :) [/QUOTE]
