black tank flush

[dave961]

My black tankflush also does not seem to be working at all. When dumping, and hooked up to good pressure,nothing at all is coming out. There must be some blockage, a stuck valve, or a kinked line. I guess I'm going to have to start at the hose connection and trace it all the wat to the tank checking every inch of the system. Disappointing, it was one of the selling features for me since I didn't have one on my last camper.

Do you use a dedicated unregulated water hose for the flush? I find this made a huge difference.

Some threads I have read say that running it with less than full pressure makes it work better. Mine didn't work like your but on the last trip it worked a bit but with low water flow. I wonder if I could spray out the inside of the tank ends in case it somehow got something dried on it which is preventing proper operation? I've also heard the check valve can be installed backwards, but have no idea where the check valve is located at.

Most likely it's debris in pipe lines jammed in the nozzle orifices. Happens to showers, sinks and faucets often. Maybe able to locate nozzle, disconnect supply line and carefully clean out fitting. While open give a good flush and prove flow.

But for me, my camping is a month old. I'm going to try and spray off the flushing mechanism by putting a manually flusher down into the toilet. I'm also tempted to fill the black real full, let it soak, then flush it a few times. I'm reading many problems with these black flushing devices for all RV makes and models. Oddly enough, never had a single problem with my quickie flush. I think the simple blaster flushers are less prone to clogging than these spinner flushers, imho.

Finally resolved (I hope). Last time out, I found the check valve (below) tucked away behind a panel. Took it apart and made sure it was working. The ball was jammed in pretty bad, but when I put it back together I was able to blow through it. But that didn't fix it, so this weekend I finally crawled under there and found the hose zip tied at 180 degrees, brilliant. Cut the zip ties and tried my best to unkink the hose - which by now wanted to stay flat.

Will test it out next trip.

Mine was installed backwards according to the dealer…

I would have no idea where mine is on the 337fb... It works a little but he pressure is so low it's kinda marginal at best

Is there a value on for black water flushing on the Vibes?
If so where?

In my 2012 Wildcat fiver the hose connection for the backwater cleanout was plumbed to fill the freshwater tank. I noticed nothing was coming out of the tank. After several trips, water came gushing out of the back of the trailer. I had unwittingly overfilled the freshwater tank. Took dealer seven weeks to fix it.

Follow up: Once properly plumbed, the BW flush system works very well.

I assume the camper was "new to you" and previously owned. Sounds like it might have been modified on purpose so the previous owner could fill the fresh water tank from the hose bib.

Actually it was brand new. Was plumed wrong from the factory. If you have ever visited an assembly line at the factory you would understand how such mistakes are made.

I have, actually. Point taken.
