Black Tank Flush

Hello all - One question about using the black tank flush valve; should I use the water pressure regulator on the hose I attach to the black tank flush connection? I have been using the lower pressure, but was curious how others hooked up. Thanks, Matt

It seems to be a pretty even split between those that do and those that don't.

Thanks - This is our first one with an external flush location, and I'm a little concerned about allowing too much pressure and having a blowout. I've already had to stretch into a very unhandy place to fix a leaky water filter, and really don't want black tank issues...Matt

For what it's worth, I haven't used a pressure regulator on my black tank flush in probably 200+ nights of camping (not that many flushes/dumps, of course).

I didn't used to use a pressure regulator, but have started to as I had a spare anyway.

The Black flush runs to what is basically a sprinkler head that lets water out, so it would probably take very high pressure to cause an issue. But since high pressure might damage something that's buried inside your Black tank (or a hose leading to it), it doesn't hurt to use one.

Never have in almost two years. I figure the more pressure at the spray head the better but I could be wrong, time will tell.

I've never used one on my black flush either.
Being it's an open ended system (nothing to hold/build pressure) there isn't much chance you'll ever see a spike of pressure inside the flush lines high enough to create any problems. 'Maybe' with the chincy, plastic anti-siphon/check valve... but that's another topic.
Like was mentioned... the more pressure you can give it, the better the flush.

I never use a regulator on my black water flush. I have a 2 spicket faucet that I screw onto the campground water, one spicket has the regulator for city water, the 2nd one does not have a regulator and the black water hose is attached to it.

I only use the black tank flush when the camper is home. My house water pressure is 80psi. Maybe the RV system can handle this pressure - and maybe not. I know I don't want to be screwing around with any black tank issues. I use a regulator.
I disagree that this is an open-ended system. Those little sprinkler openings by themselves will build pressure as they are restricting flow.

Sure they 'restrict' the flow somewhat but they wont build pressure or hold it when shut off unless your hose/supply is full of debris and clogs them.

It's open ended because there is nothing that closes off the water flow.
