Black tank flush system - use of pressure regulator

I use a regulator. It is my understanding that the fittings for the antisiphion valve and etc are same as rest of RV plumbing, which I believe is rated at 50 psi. I have personally seen over 100 psi at some campgrounds.

I hook up regulator at the CG faucet...set for 50#....then a brass 'Y'.

Hose to black tank flush is regulated for one reason........don't want to blow flush system up (backflow preventer/connections and/or actual flush head).
Been in some places where water supply pressure was very high.......80-110#...and I sure don't want that kind of pressure on the flush system.

ALL water to rig is regulated!!

Since the built in flushing device requires the drain valve to be open, there's no need to regulate the water pressure going in. Further, I keep all my potable water components, such as hoses, regulators, filters, etc., far away from my black water tank components.
Just sayin'...

as long as you are paying attention, no need for one.
