Advise needed...how do I install a 1 1/2" plastic elbow
fitting in a bladder type
? I have carefully cut the hole but can not work
the flange through the hole. To me, it is like cutting a hole the size of an orange then trying to force a grapefruit through it. I have been trying to work
the fitting in with no lubricant and thus far have started to chafe the fabric
. Not a good start. Should I lube around the hole with dish soap in hopes it will slip in? Once I get the fitting in should the perimeter of hole have any type of sealant
applied before I screw down the sealing collar?
