The CP- current
project- has 10 groco tapered plug bronze
seacocks and removable tail pieces. All of which need the fiber washers renewed. I've had two leak and made a washer for one out of thick rubber sheet and used a large diameter O-ring on the other. Both are dry but I'm leery of over tightening them.
Any experience with this? 'Seems I just can't pop down to the local West Marine
for the stock washers.
