How do you do the winterization of black tank flush system in 179? ------------- 2015 R-Pod 179 2013 Chevy K1500 |

You are the first to ask as far as I know. The system empties into the black tank. so it should be empty/drained already. there is a backflow preventer, but I am not sure on it's specs. I guess I would physically look to see if it was holding any water on the outboard side of the valve. ------------- |

I blew mine out with compressed air for 5 minutes using a compressor hose adapter. ------------- 2005 Dodge Durango 4.7 V8 OLD Tow Vehicle 2004 Honda Odyssey 2015 RP179 "73b" OLD 2005 Viking Saga 2480ST popup |

There is a check valve on the hose connection and a vacuum breaker inside behind the sink. That one foot section will hold water unless it is dealt with. Perhaps that is why so many people have leaks on that section besides forest river installing the vacuum breaker backwards. ------------- 2005 Dodge Durango 4.7 V8 OLD Tow Vehicle 2004 Honda Odyssey 2015 RP179 "73b" OLD 2005 Viking Saga 2480ST popup |

Is there any way to get pink stuff to it? ------------- 2015 R-Pod 179 2013 Chevy K1500 |

Yes. but I don't think it's necessary, five minutes of compressed air would dry the pipe. However, if you do not have access to a compressor then... Get a 1/2 female iron pipe by 3/4" male garden hose threaded adapter (large box store or plumbing supply). Connect that to your blue low point drain. Connect a clean garden hose from the low point drain to the black water flush. Put another gallon of antifreeze into the winterization hose under the bed and turn on the pump. It will pump it from the antifreeze bottle, through the low point, out the garden hose and into the black flush line. Also remember to close all of your faucets before doing this and open them afterwards. Always store the pod over winter with open faucets. ------------- 2005 Dodge Durango 4.7 V8 OLD Tow Vehicle 2004 Honda Odyssey 2015 RP179 "73b" OLD 2005 Viking Saga 2480ST popup |

The fresh water also has a check valve. But you can bump the little button on the center of the hose connection under pressure with pink and that will solve that too. Some disagree, but I also put a gallon in the fresh water tank to pinkify the suction line to the pump. ------------- 2005 Dodge Durango 4.7 V8 OLD Tow Vehicle 2004 Honda Odyssey 2015 RP179 "73b" OLD 2005 Viking Saga 2480ST popup |

No need to do anything to the black tank one. The valve has a gravity ball in it. What doesn't drain into your black tank when using it, falls back out the line when you're done. You'll always notice when you disconnect it that water will run back out of it. I've specifically asked Forest River this question because I was curious about mine years ago when they first launched. ------------- https://calendar.google.com/calendar?cid=cnBvZC5zcG90dGVyQGdtYWlsLmNvbQ - RPod Rallies https://www.google.com/maps/d/embed?mid=1W1foQXGtrjf8aYly1uh0b-bHPfI&hl=en_US - RPod Owner Map |

On my 177, the inlet for the tank flush is elevated above floor level. This line drops under the floor and then up to the check valve located near the bathroom sink. That entire section of line will hold water if not blown out during winterization. ------------- Brad & Laura B. Durango, CO 2014 RP177HRE |

We winterized with the pink stuff, do we still need to open all faucets over winter? Thanks, Viki ------------- Everything Happens 4 A Reason Pat & Viki McCartney 2015 171 {2McPods} 2014 F150 Pittsburgh, Pa |

Once the antifreeze is in the lines no need to worry about keeping them open or closed. ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

You've taken yours apart to look at it? On all of them that I've seen the line comes in, goes up to the valve and then drops from the valve through the floor to the tank. Things do get put together differently Pod to Pod at times though. ------------- https://calendar.google.com/calendar?cid=cnBvZC5zcG90dGVyQGdtYWlsLmNvbQ - RPod Rallies https://www.google.com/maps/d/embed?mid=1W1foQXGtrjf8aYly1uh0b-bHPfI&hl=en_US - RPod Owner Map |

On my 177, the hose port is on the slideout side, the check valve is on the door side of the pod (under shower sink). There is 5-6 feet of line that will not drain unless it is blown out during winterization. ------------- Brad & Laura B. Durango, CO 2014 RP177HRE |

The water inlet on the slide side is for the freshwater, on the door side of the Pod should be the BW flush hookup. They don't put them on the same side so people don't hookup non potable to potable and vice versa. At least that is the ONLY way I have ever seen a pod set up. ------------- |

Yuh actually spoke with the plant manager for the Dallas plant, they as often as possible on HRE's try to put them both on the off door side whereas Goshen does the opposite. Again, that line does not need winterizing the gravity check valve is the highest point in that system and even on a long hose the excess water is going to drain down and dribble out the bib where the hose connects on any model. ------------- https://calendar.google.com/calendar?cid=cnBvZC5zcG90dGVyQGdtYWlsLmNvbQ - RPod Rallies https://www.google.com/maps/d/embed?mid=1W1foQXGtrjf8aYly1uh0b-bHPfI&hl=en_US - RPod Owner Map |

The first time I tried to use the tank flush, there was no water flowing due to the check valve being installed backwards. I checked the lines routing trying to figure out the issue.
Seriously,,,,On my 177, the hose port is on the slideout side, the check valve is on the door side of the pod (under shower sink). There is 5-6 feet of line that will not drain unless it is blown out during winterization. ------------- Brad & Laura B. Durango, CO 2014 RP177HRE |

Yuh, I'm with you there, understand that yours is on the off door side. I just don't understand why you think that hose will not drain. The connection is lower than the check valve, why will yours not drain back out of the connection just like others? There's nothing to block the excess water from flowing back out the connector when you unhook. I can see that yes not every single drop might not come out, but any residual that doesn't just flow back out the connector piece will expand within the hose if it freezes and not cause any problem. Your hose would have to be completely full of water with no place left for it to expand for it to cause an issue. ------------- https://calendar.google.com/calendar?cid=cnBvZC5zcG90dGVyQGdtYWlsLmNvbQ - RPod Rallies https://www.google.com/maps/d/embed?mid=1W1foQXGtrjf8aYly1uh0b-bHPfI&hl=en_US - RPod Owner Map |

I guess I am assuming that since the hose port is elevated about a foot above floor level, the entire hose section under the floor will stay full. ( If I understand how gravity works??) Your results may vary....

Regardless, just glad your process works for you.
