It's a judgement call. Many here and on other RV chat groups just
drain and blow out lines and they are fine year after year.
Those folks also pour some AF down the drains to protect traps.
Others here, like me, opt to go the extra steps and pump in AF.
It makes me "feel good" that I've done all I can do to protect the system.
I can get mine done with 1 1/2 gal of AF. I get it on sale for $3 gal.
This means I can feel extra confident for a measly $4.50. It works for me!
