I think you have posted this several times so I wanted to add this.The best thing is to have a dealer do it. You need to know if you have by-pass kits installed, depending on what you have for storage tanks they need to be drained, RV non-toxic anti-freeze needs to be added to plumbing and flushed through, water lines should be blown out along with draining so if there is a place where the water was level it gets forced out. Here is a quick info for a skyline, but it really depends on what you have for plumbing.Purchase 4-6 gallons of RV approved, non-toxic anti-freeze.2. Drain all tanks, fresh water and sewage tanks.3. Turn water heater by-pass valves to by-pass position. (The by pass valves are located near thewater heater incoming lines – an access panel may have to be removed depending upon themodel.)4. Drain water heater.5. If installed, remove water filter from assembly and discard. Install diverter if included.6. Pour an amount of RV non-toxic anti-freeze into the fresh water tank to fill the tank aboveminimum water pump operating level. (Use of a long funnel may be helpful) Add more, ifnecessary, during procedure.7. Turn on pump switch and open the cold water side of all faucet fixtures. Leave open until theanti-freeze comes out (generally, pink in color). Repeat for hot water side.8. Flush toilet until anti-freeze begins to flow into the bowl and then pour one gallon of anti-freezedown the toilet to winterize the black tank.9. Pour anti-freeze down each shower/tub, lavatory sink, and kitchen sink to fill p-traps.10. To winterize gray tank(s) pour one gallon down each related sink drain.*****Now the best thing is to post a new post and see if someone has your manual to be exact.But if you get no response, and refuse to let a dealer do it, you have a little bit of info to help you. Sorry I couldn’t find the exact method for your model.
How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
The general rule of thumb is to winterize your trailer when temperatures fall below freezing (32F degrees) over a continuous 24-hour period. Depending on where you live, you may need to winterize your travel trailer as early as September, or you may not need to winterize at all.
Two to three gallons of antifreeze is sufficient for winterizing most RVs. To do this, make sure the dump valves are closed and pour a couple of gallons of antifreeze into your freshwater tank. Then, open each cold and hot water faucet until pink antifreeze comes out.
Note: We do not recommend putting RV antifreeze in your freshwater tank while in use. If your freshwater tank is exposed to freezing temperatures, the best route is to install a heating blanket.
Cover up your RV
If your RV will be outside all winter, Dack recommends investing in a cover made especially for an RV. The cover will protect against extended exposure to ultraviolet (UV) rays that can damage the paint finish. It will also protect your vehicle from wind damage, tree sap and bird droppings.
What Does it Mean to Winterize an RV? Freezing temperatures can take their toll on more than just your rig`s water lines. Winterizing is primarily about keeping your water lines from freezing by flushing them and then adding antifreeze in certain places.
Whether you`re a seasoned veteran of the road or the new owner of a travel trailer, winterizing is an essential part of storing an RV. Taking a few preventative steps can help prevent damage to vulnerable plumbing system components.
Benefits of Using Compressed Air to Winterize
Compressed air is easy to use to blow water out of your RV`s pipes. All you have to do is connect the compressor and get started. A small air compressor can travel with you or be stored in a garage at home, so you can pull it out each fall when you`re ready to winterize.
To winterize your RV, you need to drain the water tanks and plumbing lines. All water must be removed from the camper plumbing system. Then, you must pump antifreeze into the water system to prevent freezing, cracking, and further damage from colder temperatures.
You want to dewinterize an RV when the weather consistently stays above freezing. If the temperature is still inconsistent, you risk having your pipes freeze. Just like a house, if your pipes freeze and you have water in your tanks, it could damage your RV`s water systems and lead to expensive repairs.
There are three types of RV antifreeze: ethanol, propylene glycol, and propylene ethanol. Ethanol is the cheapest of the three options; however, propylene glycol is the most popular option for RVs and boats.
Does RV antifreeze go bad? As long as it`s stored properly and the cap is tightly sealed, RV antifreeze will typically have a shelf life between 1 to 4 years but can often remain effective long after that.
Once again, there is a big difference between auto antifreeze and RV antifreeze. RV antifreeze is designed to be pumped into the plumbing system of an RV and is therefore non-toxic, like marine antifreeze. In contrast, auto antifreeze is toxic and should not be used in your boat engine.
RV antifreeze rated for and minus 75-degree F will start to freeze at about +16-degrees F. But neither will freeze (solid) to the burst point until minus 50-degree F or minus 75-degree F respectively. So, in extreme cold temperatures it`s not uncommon for the antifreeze to appear slushy.
Before you can safely use your RV`s water system for showering, washing dishes, and drinking, you`ll need to flush all traces of antifreeze.
Is It Safe to Drink from Your RV Fresh Water Tank? Yes, it`s safe to drink water from your RV fresh water tank as long as you regularly maintain and sanitize the tank and water system. Your RV fresh water tank holds fresh water for drinking, cooking, cleaning, and more.
But when winterizing an RV, what you really need is air volume, not air pressure. You`ll only be blowing out your lines at 35-50 psi — any higher may damage your plumbing.
If you`ll be bringing your grill inside for the winter, be sure to turn off your propane tank and disconnect it. If your grill will remain outdoors, you can keep the tank connected, just make sure to turn the tank off. Protect it. Unlike gasoline, propane fuel doesn`t need to be winterized.
Winter Propane Tank Storage
Covering up your propane tank with a plastic tarp will keep ice from building up on the tank and snow off of the tank, which will prevent resting and helped extend the life of your tank.
Pour one quart of special RV antifreeze into the gray and black tanks to protect the drain valves and seals. Do this through all sink and shower drains—you want antifreeze in the pipe traps as well. Add about a pint to the toilet bowl to protect its flush valve and seals.
Prevent your black water tank from freezing
You probably won`t want your black water tank to freeze again after you thaw it out. Dump a gallon of RV antifreeze into the tank via the toilet to help keep it from freezing again.
Is it Okay to Leave Your RV Plugged in All the Time? Again, the short answer about keeping your RV plugged in all the time is – no. The risks include battery damage from overcharging and frozen refrigerator coils, as most RV refrigerators need to be periodically cycled off and thawed.
Apply a Cover to Your RV We recommend buying RV covers by ADCO or Camco because both manufacturers offer a quality build and great selection. A cover will prevent snow accumulation and ice buildup on your unit`s exterior, and it will keep meltwater from creeping into the seams between panels and components of your RV.
Depending on how your unit was winterized it will need to be de-winterized, but make sure the freezing temperatures are over for the season before you do. Basically what needs to be done is to flush all of the non-toxic RV antifreeze out of the RV plumbing system.
