that is the main reason that lots of stuff get put into the directions, lawsuits from fools.

Yup, sad but true!

It is funny sometimes when people get so serious about every little detail on the manufactures directions.

I am looking for somebody to pull the tag off of my mattress on my new RV.
bumpy

OMG........don't pull the tag!

Thanks for all the replies - I appreciate your input on the matter.

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'...

I don't use a pressure regulator since you want as much pressure as possible to clean the tank.

I don't think "requires" is the correct word.

I drain the black tank then I close my black valve for 5 minutes while flushing then open and let it flush for 5 minutes then close and fill for one minute then add chemicals.

I set the timer on my phone so I don't forget and have a fountain coming out the top of my RV.

I only used "requires" because my owner's manual specified the condition. Of course there is no lock-out preventing the operator from leaving it closed. I doubt the "black water police" would cite you for using your method and "violating" the "requirement". ;)

I dont. Works fine. I also use it to add water to tank after draining. I time it so i dont get too much or little!

Since the flush system is always open at the sprayer, it can't build pressure. Since it can't build pressure, no need for the regulator.

Yep, there is a big difference between flow and pressure. No pressure regulation needed in an open line.

It's not necessarily an open line. The tank sprayer does have backpressure or creates a flow restriction, thus pressurizing the line behind it that feeds the sprayer. Over pressurization of the line to the sprayer could cause issues, such as bursting the cheap vacuum breaker or popping a pex line.

I don't use a regulator, but if there was excessive pressure I would put it on.
