What's wrong with plastic backnuts for wastes .

I thought they were frowned on here, but perhaps that's just tap
backnuts rather than all plastic backnuts?

Why do you need a spanner for waste backnuts? Just use your
hands ..they don't neeed to be that tight and anyway

I was using a pair of pump pliers but they chew into the plastic where
you grip them. I thought they had to be tight. I was afraid of them
leaking if they were too loose.

I have a slight leak from the bottom of the banjo but all other joints
are ok.
