I got this PDF from “tiffinRVnetwork” and it is a very good explanation of how the vacuum breaker/check valve works in the black water flush system.

Suggestions for replacement are Watts LF288A or Cash Acme V-101

Keep in mind that these are Vacuum Breakers only they do have a built in check valve. A check would have to added to make them the same as the B&B model 571 vacuum breaker/check valve. ]]> Wed, 05 Oct 2016 21:57:15 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83197#83197 Black tank flushing? : Originally posted by Happy... https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83192#83192 Author: johnbryanpeters

I have ordered the V-101, and plan to relocate it when I install it.

Pardon the question from a non-plumber - How do you intend to join the new metal valve to the current non-metal tubing?
Go to my local hardware store and buy the appropriate fittings. The valve is 1/2" NPT, the tubing's PEX compatible (1/2" NSF61-9 cold/hot 150 PSI). I'll probably buy brass adapters because they're stronger.]]> Wed, 05 Oct 2016 18:23:39 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83192#83192 Black tank flushing? : Originally posted by johnbryanpetersSuggestions... https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83190#83190 Author: Happy Tripping

My vacuum breaker/check valve was leaking on my 177. It turned out to be a loose fitting so I just tightened it by hand and the leak stopped. I just pulled the wall back enough to get to the valve. The corner molding and 1/8" paneling are held in place with staples. It is very easy to remove the paneling. The other thing I found was the sprayer mounted in the back water tank was clogged up and so there was a lot of back pressure which contributed to the leak. The back water flush valve is held in place with 3 screws. I took it out and unscrewed the fitting from the hose and that's when I saw all the buildup inside it. Took a small brush to clean out the gunk. The small holes that water squirts out of had burrs and had never been cleaned up. I used a sharp exacto knife and a welding torch tip cleaner to remove the burrs. Everything is working as it should]]> Wed, 05 Oct 2016 17:19:39 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83188#83188 Black tank flushing? : Diagnosis of flush issue:Had... https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=83176#83176 Author: johnbryanpeters

Diagnosis of flush issue: 

Had to cut into bedroom wall under 125 VAC electrical outlet (!) to access valve. It was a B&B model 571 vacuum breaker, made of plastic, which had failed. Research on web tells me that these fail frequently.

Just tried to flush the tank on my 2013 (2014?) RP-171; it had seemed to work before, this time pressure built up and the valve sprayed water. It seems I will have to cut a hole in the wall either in the sleeping area or behind the toilet to get at the valve. Grrr...

Notes:

1) The valve is both a check valve and a vacuum break. Its primary purpose is to prevent sewage from making its way back into the hose you're using to flush the tank.

2) As I spend more time using and maintaining this trailer, the evidence of sloppy workmanship is astounding.

Yes, the guys at Camping World told me the same thing about 2/3 - 3/4 full (and it confirms that in the owners manual as well:)
This may be a dumb question, but when you say you fill it all the way... do you mean pouring water in via the toilet bowl, or via the black tank flush portal?

Also be sure the black tank is at least 2/3 full before emptying it, to ensure the solids are removed. Before the addition of the black tank flush sprayers, this was the only way to clean out the tank. At the end of the season I fill it all the way and dump it, twice.

I believe many chemical treatments say to add several gallons of water so we add 2-3 toilet bowls worth.]]> Tue, 07 Jun 2016 13:06:47 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=76727#76727 Black tank flushing? : Originally posted by GLBCamperI've... https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=76677#76677 Author: CharlieM

You should keep some water in the tank, but it doesn't take much. One toilet bowl full is plenty. That keeps the dump valve seal and the lower parts of the tank wet. If you're driving it takes even less due to the sloshing. Make sure you have just enough water in the bowl itself to cover the blade seal, but not enough to slosh out on the floor while traveling.

The purpose of the black tack flusher is to clean out the black tank. You don't have to do it every time, but certainly after each trip and before long term storage. Just dumping the tank can leave solids behind. If left to dry these can build up clogs. Flushing the tank prevents this and also cleans the probes for the tank monitor. If you have the time it never hurts to flush the tank at least once after you dump it.

This may seem like a dumb question, but different places I've dumped have no supply hose connection on the clean out side. So if I go to an available hose connection somewhere else and clean out the blackwater tank with the blackwater valve open am I going to run blackwater on the ground while cleaning out the tank?]]> Sat, 25 Oct 2014 10:38:47 +0000 https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=53221#53221 Black tank flushing? : Same thing for me on a 2014 182g.... https://www.rpod-owners.com/forum_posts.asp?TID=4878&PID=53014#53014 Author: Scoul

Awesome, glad you found it.  If it's convenient for you to have your dealer do it I would.  I let mine do several warranty things that I could have done myself just because of it being new as well!

Please let us know for sure if it does just indeed be installed backwards, a silly mistake at factory for sure but one that is annoying when it's your trailer that it happens to.
