Have them throw it into the deal its not an expensive up grade.


Oaklevel brings up a good point about getting in thrown into the deal. We are complete newbs, so we will be needing a WD hitch and all the basic items. Besides the tank flush, anything else you all suggest to try to get throw in or at least talked down?

Thanks

Flush port Below Black Tank is NOT the proper location! Check valve failure means Sewage flowing out of the garden hose port! Port Must be higher than the Black Tank! Youroo!! The Next person using that fresh Water supply is wanting Safe Water not Contaminated!

Thanks

I had max air covers put on all vents and the bed slide with a topper. Cost to them is minimal on the covers but I didn't want to have to do it while working too. They call back in 5 minutes to agree with no price increase.

When the factory check valve, in the vanity, started leak'n in this unit, I went to HD and bought a brass backflow valve for a house....did away with 12' of extra hose, and inserted the new valve in the factory line

On all my previous RVs, no. But, for some reason my Wildcat black tank doesn't drain well. Since it has the built-in flush, I find it useful.

Well we ordered the unit today and made sure it had a black tank flush on it. They said they would put a Tornado on it.

I would hate to not have one on my unit. Pretty simple to hook up a hose to flush the black tank.

And where do you think the garden hose connection to the RV is? It's below the level of the "Flush port" connection - all you've got is a solid hose connection all the way from the park's garden hose bib, through the garden hose, through the flush port (which is simply a gasketed hose connection), through the manual shut-off valve, to the back flow preventer (The thing everyone's incorrectly referring to as a check valve, and which has to be above the highest part of the black tank), then on to the black tank. To contaminate the park water system, you would have to have the black water drain closed, completely fill the black tank until the flush nozzle within the tank is completely submerged, the back flow preventer would have to fail, you would have to leave the garden hose attached to the park bib, and the manual valve at the flush port connection would have to be left open. Highly unlikely. Locating the flush port connector below the tank makes no difference.
If you want to protect the park's fresh water supply, you should use a back-flow preventer on the park end of your black water flush hose.
And what keeps us from contaminating the park water system if we attach one of those back-flushing gate valve attachments at our drain outlet??? Without a back-flow preventer at the park bib, you're still in a position to contaminate the park supply.
It should be standard practice for the park to have backflow preventers at the hose bib, but I've only seen it at one park.
I believe plumbing codes now require this backflow prevention on all outside hose connections.
