Black Tank Flush, Jay Flight 285 RLS

I have a new 2018 Jay Flight 285 RLS
Should I use a pressure regulator when using the Black Tank Flush or not?

IMO it isn’t necessary to use one. The business end of the tank flush is open, therefore it won’t build pressure. You’ll just get the working pressure of the water system, not the static pressure.

Unless your water source has insanely high open pressure. I would worry about it.

Unless your water pressure is unusually high, it shouldn't matter since the black rinse is an open system... in other words pressure does not build up since if the water is on the system is rinsing. Typically I put a Y on the bib then my pressure regulator/filter and hose, so when I connect my black tank rinse to the other half of the Y it is not regulated...

Exactly how I do it.

Keep in mind that the black tank flush water line has an anti-siphon valve (vacuum breaker) and those plastic valves are prone to leak under to much pressure........, know where your's is located so you can keep an eye on it. I believe the valve is only rated around 50 pounds of pressure.

Welcome to the forum.


No and my setup is like wags999.

I've never used one and doubt it would be necessary since the black flush should only be used while the black tank valve is open. I'd have to imagine it would require a severe overpressure in the water supply to do any kind of damage to the line while the black tank valve is open.

Keeping Murphy’s Law in mind, what about putting the pressure regulator between the bib and the Y? That way either side is protected....just in case.

You certainly can put the regulator first. I just like the higher presser on the rinsers, seems to do a better job in my opinion.

I never have. At my sons house the water pressure is 80 plus. My concern is the amount of crap that will stick to the flush nozzles.
