Flush regulate?

[drizzamed]

I'm guessing not and probably better if not, but is it necessary to regulate the water pressure when flushing the black tank via the flush tank connection?

That is probably not often done and probably doesn't need to be but it would be good to know what the supply pressure is as extremely high pressure might cause some problem.

^^^ I agree with Kirk.
Extremely high pressure could blow the feed hose loose from the connection.

I once stayed in a park that had 160psi water pressure. They required regulators and had loaners if you didn't have your own.

Wow 160psi might blow up a flush system and can cause a lot of problems with just about any R-V.
I've been in the habit of filling my fresh tank and running my pump.
I had 160psi in a rental house and was setting off the water heater high temp-high pressure valve. Found out when I bought a gauge to put on the outside faucet. The gauge is in the R-V now if I decide to use their water hookup, with my regulator of course.
Glad it didn't blow out the house pipes.

I have used a pressure gage on the inlet side such as this one from Camco, which I got years ago and still use. They used to be quite common but are difficult to find now. There are hose end type gages readily available.
